Such tables, hwever, are f lttle value n the szng f functnal clthng r headgear, where knwledge f the nter-relatnshp between crtcal measurements f dscrete sub-grups f the ppulatn s requred. Fr example there s lttle value n the headgear desgner knwng that the 50th percentle head crcumference s 576 mm when he cannt, frm the percentle tables, determne the range f head breadths r head lengths f the 50th percentle head-crcumference subjects. Furthermre, the crrelatn between any par f head measurements relevant t headgear szng s t pr t enable that apprach t be used satsfactrly fr practcal szng purpses. Ths pr crrelatn s well llustrated at Fgs. 1 t 8 nclusve whch shw dstrbutn plts based n the 2000 R.A.F. arcrew survey 1 f head breadth aganst head length, head breadth aganst head crcumference, head length aganst head crcumference etc. t s als llustrated at Table 39 where the crrelatn ceffcents f pared head measurements are tabulated. n ths Reprt specmen sze-rlls fr arcrew headgear are presented, based n the head measurements btaned frm the 1970/1971 anthrpmetrc survey f 2000 R.A.F. arcrew. The sze-rll data are tabulated n a frm readly usable by the desgners f mltary arcrew and ther headgear. These data defne sze-rll head measurements t whch the desgners f headgear wll need t apply allwances fr helmet shell clearance etc., and t prvde apprprate nternal fttng adjustments. Fr reference purpses the percentle tables f the head measurements recrded n the 2000 R.A.F. arcrew survey, tgether wth a defntn and a phtgraph llustratng the measurng technque, are reprduced at Tables 1 t 20. These tables are preceded by the Vsual ndex at Fg. 9 t smplfy reference t the data. Fr full detals f measurng apparatus, subject psture durng measurement, defntn f anatmcal and statstcal terms etc., reference shuld be made t the Reprts publshed n the 1970/1971 Anthrpmetrc Survey f 2000 R.A.F. arcrew (A.R.C.R. & M. 3772). n addtn t the arcrew head data btaned frm the 1970/1971 survey n whch ths Reprt s based, data n a greater number f head measurements were btaned frm 500 R.A.F. arcrew n a further survey n n whch phtgrammetrc technques were used.

Arcrew Headgear Szng Mltary arcrew headgear ranges n cmplexty frm the smple head-set whch acts as a carrer f nse attenuatng earpads, telephnes and a mcrphne t the sphstcated prtectve helmet whch envelpes the cmplete head and may have t prvde r pssess any r all f the fllwng faclteg and prpertes: () nter-cmmuncatn () () (v) (v) (v) (v) (v) (x) (x) (x) (x) (x) (xv) External nse attenuatn Breathng xygen Pressure prtectn Buffet, crash mpact and penetratn prtectn Escape ar-blast prtectn Glare prtectn Brd-strke prtectn Laser prtectn Nuclear-flash prtectn Chemcal and blgcal agent prtectn Thermal cndtnng An adequate feld f vsn Lw verall weght

T meet the requrements n the abve lst, especally thse whch relate drectly r ndrectly t arcrew cmfrt, and thereby effcency, t s mprtant that the headgear prvdes an acceptable standard f ft. Althugh n certan nstances where adequate adjustments can be prvded a sngle sze may be practcable, ths s the exceptn rather than the rule. Nrmally, arcrew helmets are prvded n a range f szes and the helmet desgn s such that each sze prvdes a range f nternal adjustments t cater fr lmted varatns f certan head measurements. Such adjustments are usually acheved by nternal webbngs, packng pads etc. wthn the hard shell f the helmet. Fr ptmum ft and prtectve perfrmance t s necessary fr the headgear szng t be based accurately n the anthrpmetry f the wearer ppulatn. t s ths Reprt's purpse t prvde U.K. arcrew headgear desgners wth such data, n a readly usable frm, frm whch sze-rlls f many types f headgear may be determned Statstcal Apprach A cnventnal statstcal apprach t szng arcrew headgear has been adpted fr the szng prgrammes cvered by ths Reprt. Ths nvlves the selectn f ne r tw key measurements and the dvsn nt subgrups f the ranges f these measurements. Wthn each f these sub-grups there s a defned range f the key dmensn(s). The subsdary head measurements f all subjects fallng wthn each sub-grup are separately cmputed t prvde the ranges and percentle data f these subsdary measurements whch apply t the szes f headgear defned by the key r drect-cntrl measurements. Fr example, f head breadth s taken as the drect cntrl measurement, ts range frm the survey data at Table 1, s 140 mm t 180 ram. Assumng a 4-sze equal step headgear sze-rll and 100 per cent cverage f the ppulatn, the ppulatn sub-grups wll cmprse subjects havng head breadths f: Sze 1 Sze 2 Sze 3 Sze mm t 149 mm 150 mm t 159 mm 160 mm t 169 mm 170 mm t 180 mm (Measurement f the subjects n the 1970/1971 anthrpmetrc survey was t the nearest mllmetre.) Each f the abve sub-grups s then analysed t prvde the percentles and range f each subsdary head measurement n that sub-grup Selectn f Drect Cntrl Measurement Range ntervals The chce f sub-dvsns f the cntrl measurement range wll depend upn a number f factrs such as: (a) The lgstc dsadvantages f a large number f szes f headgear, (b) the degree f adjustment fr the cntrl measurement(s) whch can be prvded and/r accepted by the headgear under cnsderatn, (c) the degree f adjustment whch can be prvded fr the majr subsdary, r ndrect, cntrl measurements by the headgear under cnsderatn. Whether the sub-dvsns are based n the 100 per cent range f the cntrl measurement(s), r, fr example, the 1st t 99th percentle wll depend upn the degree f ppulatn cverage requred fr specfc frms f headgear. There are bvus dsadvantages n the use f a reduced range, n necesstatng the addtnal prvsnng f specal custm-made tems fr the excluded subjects r acceptng that sme subjects cannt be ftted. Such custm-made tems are lkely t be mpractcable, n cst grunds, fr sphstcated headgear depends fr ts manufacture upn expensve frmers. There are, hwever, equally bvus advantages n reducng the sub-dvsn ranges by caterng fr, say, the 1 st t 99th percentle r 3rd t 97th percentle ranges f the key measurement as such a reductn eases the task f the headgear desgner n terms f the headgear adjustment ranges he has t prvde fr. The chce f cntrl measurement range upn whch the sub-dvsns are based must therefre be decded by r, mre prbably, fr the headgear desgner fr the specfc tem f headgear beng cnsdered. Althugh t s bvusly desrable t be able t ft all traned men, caterng fr the full range f the cntrl measurement(s) may requre an ncreased number f sub-dvsns, and hence mre headgear szes, r, alternatvely, carser sub-dvsns necesstatng the prvsn f ncreased adjustments n the fnal headgear. As an example, frm Table 1 the 100 per cent range f head breadth s 40 mm whlst the 1st t 99th percentle range s 25.8 ram. Therefre, f fr desgn reasns a maxmum 'wthn-sze' range f 10 mm were

6 dctated, cverage f the full range f head breadths wuld requre fur szes, whereas cverage f 98 per cent f head breadths wuld requre nly three szes. Lgstcally ths s a hgh penalty t pay fr the nclusn f an addtnal 2 per cent r less f subjects. t may be justfed, hwever, n terms f verall ecnmy when cnsderng the dsprprtnate cst f specal-t-measure headgear fr subjects excluded frm the sze-rll, rejectn f expensvely traned armen fr certan peratnal rles because specal-t-rle helmets d nt ft them r, n the chemcal r bacterlgcal envrnment, falure t prvde prtectn fr 'versze' r 'undersze' persnnel. These cnsderatns have nfluenced the cntrl measurement ranges adpted fr the sze-rlls utlned n Sectn 3 f ths Reprt. The maxmum practcal cverage f the cntrl measurement ranges has been used, n sme cases the 100 per cent range where t nvlves lttle penalty, and n ther cases ranges such as the measurement range f the mnmum plus ne, tw r three men t the maxmum mnus three, tw r ne man. By ths latter means 'freak measurement' ndvduals wh wuld extend the cntrl measurement range f ncluded n the sze-rll can be mtted wth very lttle penalty. t shuld be stated that the mnmum and maxmum values f the head measurements recrded durng the 1970/1971 anthrpmetrc survey f R.A.F. arcrew, upn whch ths headgear szng prgramme s based, are nt necessarly the mnmum and maxmum values f thse measurements t be fund n the ttal R.A.F. arcrew ppulatn. t s therefre prbable that n selectng a cntrl measurement range f, say, the 'mnmum plus three' man t the 'maxmum mnus three' man's measurements, mre than the sx subjects wuld be excluded frm the sze-rll when cnsderng the whle R.A.F. arcrew ppulatn Selectn f Subsdary Measurement Ranges n the chce f the subsdary measurement ranges t be accmmdated wthn each sze f headgear, the headgear desgner s gven sme lattude by the methd f presentatn f the sze-rll data utlned at Sectn 3. f exclusn f further subjects frm the sze-rll beynd thse whch may already have been excluded by lmtng the cntrl measurement range s undesrable, the desgner must cater n the headgear desgn fr accmmdatn f the full range f each subsdary measurement. The specmen sze-rll data d hwever allw a chce f subsdary measurement range cverng 100 per cent, 1st t 99th percentle, 2nd t 98th percentle etc., measurement f the mnmum plus ne, tw r three men t the measurement f the maxmum mnus ne, tw r three men etc., r a range chce based n values determned frm the measurement mean and the standard devatn (S.D.). Where there s a Nrmal (Gaussan) dstrbutn the fllwng apprxmatns apply: Mean _ SD = 84th t 16th percentle Mean _ SD = 90th t 10th percentle Mean SD = 93rd t 7th percentle Mean SD = 95 t 5th percentle Mean SD = 99th t 1st percentle Nte 1. Care must be exercsed n ths latter apprach as the 'wthn a sze' data presented at Tables 23 t 37 nclude many dstrbutns whch are sgnfcantly skewed. Nte 2. The percentle values gven at Tables 23 t 37 have been derved by lnear nterplatn between successve measured values. Fr thse measurements whch drectly nfluence headgear ft, the desgner must accmmdate the largest sze n the selected range f cntrl r subsdary measurements and prvde suffcent nternal webbng and/r paddng adjustment t ensure a ft n the smallest sze n the selected measurement range. Such adjustment wll f curse be addtnal t the skull/helmet shell clearance dctated by the necessary head deceleratn dstance and mpact attenuatng and lad spreadng ftments fr the largest head t be accmmdated by each helmet sze Selectn f Drect Cntrl Measurements The chce f cntrl measurement(s) upn whch the szng prgramme shuld be based depends n a number f factrs such as: (a) The head measurement(s) n whch the helmet desgn requres the greatest degree f cntrl. (b) Measurements whch can readly be nterpreted and used by the desgner n the desgn f a specfc headgear. (c) Measurements whch crrelate best wth a pared cntrl measurement and/r wth the mre mprtant f the subsdary r ndrect cntrl measurements..

7 (d) Measurements whch can readly be taken n the subject, fr headgear ssue purpses, by persnnel unacquanted wth sphstcated anthrpmetry. These factrs have been brne n mnd n the selectn f the cntrl measurements upn whch the specmen sze-rlls defned n Sectn 3 f ths Reprt are based. n a reprt f ths nature the requrements f the headgear desgner must be antcpated n chsng the cntrl measurements and the sub-dvsns f the cntrl measurement ranges used. Sme mplcatns f the use f sngle r twn cntrl measurements are cvered at Sectn 4 f ths Reprt where the results f the specmen sze-rll cmputatns are dscussed. There are, hwever, ptental dsadvantages n usng twn cntrl measurements, prmarly frm the lgstc pnt f vew. Frm the use f a sngle cntrl measurement the number f szes f headgear relates drectly t the number f cntrl measurement range ntervals selected, whereas wth twn cntrl measurements the number f szes f headgear requred wll nrmally be the prduct f the number f range ntervals fr each cntrl measurement. Thus headgear based n, say, three range ntervals f head breadth and fur range ntervals f head crcumference culd nvlve 12 szes f headgear. Ths twn cntrl measurement apprach may be justfed f the requred degree f drect cntrl n tw crtcal measurements can nly thus be btaned. Thse szng prgrammes at Sectn 3 f ths Reprt n whch twn cntrl measurements have been used have been lmted t a maxmum f sx szes, nvlvng cmbnatns f tw and three range ntervals f the tw cntrl measurements. 3.

As recrded at Sectn 2.4, these tables prvde the headgear desgner wth a chce f subsdary measurement ranges frm whch the mst apprprate ranges fr partcular applcatns may be selected. The penaltes ncurred by dfferng chces f subsdary measurement ranges, n terms f the number f subjects r percentage f the specfed grup ppulatn excluded by the sze-rll, can als be determned frm Tables 23 t 37.

The prs and cns f these appraches fr such headgear are dscussed n Sectn 4 f ths Reprt. t may reasnably be argued that the ffteen appraches t headgear szng cvered by ths Reprt shuld have been analysed prr t ts draftng and nly the few szng appraches gvng the better theretcal slutns ncluded. Hwever, the authr beleves that the headgear desgner shuld be prvded wth the full facts and thus be free t adpt cmprmse slutns whch best meet hs wn partcular requrements rather than thse f the theretcan. The statstcal data presented at Tables 23 t 37, whlst nt gvng the headgear desgner a cmprehensve cverage f all pssble appraches t headgear szng, at least antcpate the majrty f queres whch wuld prbably be psed were he t be presented wth a sngle 'theretcally best' slutn t headgear szng General 4. Dscussn Fr cnvenence f dscussn f the relatve merts f the sze-rlls cvered by ths Reprt sme f the data f the mre mprtant measurements frm Tables 23 t 37 have been summarsed at Table 38. Fr cmparatve purpses nly, that table lsts the 2nd and 98th percentle values and range f selected measurements applcable t each sze wthn each f the cnsdered sze-rlls. The presentatn f the 2nd t 98th percentle range s a purely arbtrary chce fr data cmparsn purpses whch avds pssble nfluences n the subsdary measurement ranges by 'freak' subjects at the range extremes. t s pnted ut, hwever, that the headgear desgner may, f necessty, have t cver ranges f subsdary measurements greater than the 2nd t 98th percentle: that pnt has been cvered at Sectn 2.4 f ths Reprt. f ranges f subsdary measurements ther than the 2nd t 98th percentle are t be utlsed, reference shuld be made t the full sze-rll data at Tables 23 t 37 t check whether the bservatns made n ths dscussn sectn stll apply. t shuld be nted that Table 38 lsts the 2nd t 98th percentle values f the sx measurements whch are used as cntrl measurements fr sme sze-rlls but are subsdary measurements n ther sze-rlls. Where these partcular measurements are used fr sze-rll cntrl,.e. where shwn astersked (*) at Table 38, ther full sub-grup ranges as stated at the tp f Tables 23 t 37 shuld be used by the headgear desgner, as the subsdary measurement data at thse tables have been cmputed frm the full sub-grup ranges f the cntrl measurement(s). These cntrl sub-grup ranges are fr cnvenence als lsted n Sectn 3 f ths Reprt. The desgner f a specfc frm f headgear may have verrdng reasns fr selectng a certan cntrl, r par f cntrl, dmensn(s) and/r tarff f headgear szes. Fr these reasns the fllwng sectns n whch the relatve merts f the varus appraches dealt wth n ths Reprt are utlned can, at best, nly serve as a brad gude. Fr example, n sme current strke arcraft mnmal helmet wdth s f crtcal mprtance n enablng the wearer t btan a maxmum vsual feld wth the sde f the head/helmet cmbnatn n cntact wth the arcraft canpy. Smlarly, n sme nstances excessve helmet (fre-aft) length mght be an embarrassment by pstnng the subject's head n an unnatural atttude aganst the arcraft seat headrest. The reasnng supprtng the chce f the wde ranges f the cntrl measurements adpted are utlned at Sectn 2.3 f ths Reprt and fr certan headgear applcatns t may justfably be argued that these ranges are unnecessarly r unecnmcally wde. Hwever, n a Reprt f ths type t s nt pssble t prvde data cverng all pssble requrements as regards chce f verall cntrl measurement(s) range. Alternatve cntrl measurement range data can f curse be determned frm the cmputer banked data f requred. An nstance f the pssble shrtcmngs f the use f a wde ttal range f cntrl measurements s ndcated at Table 25 Part 1 and Table 25 Part 6, where thse tw szes n that sze-rll nvlve nly 33 and 37 subjects frm the 2000 survey ppulatn respectvely. Such small numbers f subjects, 1.65 per cent and 1.85 per cent f the arcrew survey ppulatn, mght be thught barely t justfy the prvsnng f thse szes f headgear. T prvde nfrmatn frm whch the practcal effect n the cnsdered sze-rlls data f the crrelatn ceffcents f pared head measurements can be deduced, Table 39 s ncluded whch tabulates the crrelatn ceffcents f all subsdary measurements wth relatn t the cnsdered cntrl measurements.

The 2nd t 98th percentle ranges and values f subsdary measurements are very smlar fr all three sze-rlls and adptn f sze-rlls B r C n preference t sze-rll A (three szes) culd nly be justfed f very clse cntrl f head crcumference s requred r the asscated margnal reductn f head-breadth and head-length ranges, whch ccur wth ncrease f the number f szes based n head-crcumference cntrl, s mprtant. Frm Table 38 Parts! and 2 t s apparent frm the data lsted aganst sze-rlls D, E, F and G that nly a requrement fr very clse cntrl f head breadth (sze-rlls D and E) r head length (sze-rlls F and G) wuld justfy adptn f the three-sze rll, reference E, n preference t the tw-sze rll, reference D, based n head breadth r the three-sze rll, reference G, n preference t the tw-sze rll, reference F, based n head length. Of the sngle cntrl dmensn sze-rlls wth three szes (sze-rlls referenced A, E and G based n head crcumference, head breadth and head length respectvely) whch can be drectly cmpared there s lttle dfference n the 2nd and 98th percentle values r ranges gven at Table 38 Parts l and 2 fr the nn-cntrl, r subsdary, measurements. Thus chce f the cntrl measurement t be adpted by the headgear desgner wuld depend upn the relatve mprtance f cntrl f head crcumference, head breadth r head length. f frm a sngle measurement cntrl sze-rll, lmtatn f the measurement ranges f head crcumference, head breadth and head length are requred, there s sme advantage n adptng head crcumference as the szng cntrl. Ths advantage des nt hwever extend t the subsdary measurements where the 98th percentle values and 2nd t 98th percentle ranges fr sze-rlls A, E and G are very smlar fr cmparable sze-rll szes. t s pnted ut that whlst head crcumference s a cnvenent measure fr helmet fttng and ssue purpses, head length and head breadth are lkely t be f mre mprtance t the headgear desgner n defnng a rgd-helmet-shell prfle wthn whch the apprprate maxmum head crcumference and the requred harness webbngs, packng pads etc., must be accmmdated. t s essental that the rgd shells f crash helmets accmmdate the maxmum subject head breadths and head lengths f the ntended ppulatn sub-grups n addtn t skull/shell clearance fr mpact attenuatng and lad spreadng devces and/r materals and nse-attenuatng earpads. The adptn f ether sze-rll E (three-sze head-breadth cntrl) r sze-rll G (three-sze head-length cntrl) naturally nvlves the accmmdatn f greater head crcumference ranges than apply t sze-rll A whch s based n head crcumference cntrl. There s, hwever, cnsderable evdence frm current nservce mltary headgear that these greater head-crcumference ranges can be adequately catered fr Twn Cntrl Measurement Sze-Rlls The twn cntrl sze-rlls cvered by ths Reprt are: Head crcumference/head breadth--fur szes (sze-rll H) Head crcumference/head length--fur szes (sze-rll J) Head breadth/head length--fur szes (sze-rll K) Head breadth (3)/head length (2)---sx szes (sze-rll L) Head length (3)/head breadth (2)--sx szes (sze-rll M) Head breadth/mentn t vertex--fur szes (sze-rll N) Head breadth/mentn t back f head--fur szes (sze-rll O) Head breadth/mentn t back f head mnus head length--fur szes (sze-rll P). Nte 1. The fgure n brackets ( ) after each measurement at sze-rlls L and M abve ndcates the number f range sub-dvsns used. Nte 2. Sze-rlls N, O and P are ncluded prmarly fr pssble applcatn t 'encapsulatng' headgear n whch the mentn (chn) s enclsed wthn the hard shell f the helmet. These sze-rlls, whch nclude a mentn lcatn measurement as ne f the cntrl measurements, are further dscussed at Sectn 4.5. A cmparsn f the 2nd and 98th percentle values and range data at Table 38 Parts 3 and 4 fr sze-rlls referenced K, L and M ndcates that there s lttle practcal advantage n usng the sx-sze-rlls L r M n 10

12 preference t the fur-sze-rll K. The nly justfcatn fr s dng wuld be t prvde a clser degree f cntrl f head breadth (sze-rll L) r clser cntrl f head length (sze-rll M), bth f whch measurements have three range sub-dvsns n ther respectve sze-rlls. The 2rd and 98th percentle values and range data frm Table 38 Parts 1, 2, 3 and 4 fr sze-rlls H (head crcumference/head breadth), J (head crcumference/head length) and K (head breadth/head length), each f whch cnssts f a rll f fur szes, can be drectly cmpared. Such a cmparsn shws lttle practcal dfference between the values, r ranges, fr equvalent szes f the subsdary measurements fr the three rlls. The desgner's chce f tw cntrl measurements frm head crcumference, head breadth and head length fr a fur-sze-rll wuld depend upn the tw measurements ver whch the greatest degree f cntrl (.e. the smallest measurement ranges r 'wthn sze' maxma) are requred. There are generally cnsderable dfferences n the 2nd t 98th percentle ranges and f 98th percentle values, fr equvalent rll szes, f any ne f these three measurements dependng upn whether r nt t s ncluded as a cntrl measurement. Cnsderng brefly the pssble use f the fur-sze-rlls N, O and P fr szng cnventnal prtectve helmets,.e. thse nt ncludng the chn wthn the hard helmet shell, t s apparent frm a study f the data at Table 38 that such an apprach wuld mpse penaltes n the frm f ncreased 'wthn sze' ranges f head crcumference and head length althugh nt havng a sgnfcant effect n the range values f the subsdary measurements when cmpared wth the ther szng appraches. t s perhaps wrth ntng that the 'wthn sze' pupl t vertex 2rd t 98th percentle ranges are smewhat smaller wth sze-rll N (head breadth/mentn t vertex cntrl) and sze-rll P (head breadth/mentn t back f head mnus head length cntrl) than wth any f the ther twn cntrl sze-rlls cnsdered n ths Reprt Cmparsn f the Merts f Twn Cntrl and Sngle Cntrl Measurement Sze-Rlls The fllwng bservatns are made n the 2nd t 98th percentle range data and thse actual percentle values tabulated at Table 38 Parts 1, 2, 3 and 4. A cmparsn f the data fr the fur-sze-rll reference B, based n the sngle cntrl f head crcumference, wth the fur-sze-rlls based n twn cntrl measurements and referenced H (head crcumference/head breadth cntrl) J (head crcumference/head length cntrl) and K (head breadth/head length cntrl) ndcates that: () As s t be expected, the 2nd t 98th percentle range f head crcumference s less wth sze-rll B, where the ttal measurement range s dvded nt fur sub-grups, than wth sze-rlls H and J where the head crcumference cntrl measurement s dvded nt tw sub-grups. () The 2nd t 98th percentle ranges f head crcumference are cnsderably less wth sze-rlls B, H and J where that measurement serves as a cntrl, than wth sze-rll K where head crcumference s nt a cntrl measurement. () Twn cntrl sze-rlls H and K whch nclude head breadth as a cntrl measurement have smaller 2rd t 98th percentle ranges f that measurement than sze-rlls B and J where head breadth s nt a cntrl. Hwever, t s perhaps wrth ntng that there s lttle dfference n ths measurement percentle range fr szerlls B and J whch are based n sngle and twn cntrl measurements respectvely. (v) Twn cntrl sze-rlls J and K whch nclude head length as a cntrl measurement have smaller 2nd t 98th percentle ranges f that measurement than sze-rlls B and H where head length s nt a cntrl measurement. (v) The 2rd t 98th percentle data n subsdary measurements (.e. thse nt used fr sze-rll cntrl) fr sze-rlls reference B, H, J and K shw n supprt fr adptng the twn cntrl sze-rlls n preference t the sngle cntrl sze-rll. Any decsn t adpt a twn-cntrl sze-rll wuld appear t be dependent upn the degree f need fr clse cntrl f tw partcular measurements. A smlar cmparsn f the data at Table 38 fr the sx-sze-rlls referenced C, L and M n whch sze-rll C s based n head crcumference as a sngle cntrl, sze-rll L s based n the twn cntrls head breadth (three range ntervals) and head length (tw range ntervals) and sze-rll M s based n head length (three range ntervals) and head breadth (tw range ntervals) shws, as wth the prevus cmparsn f fur-sze-rlls, lttle s t be ganed frm adptng twn measurement cntrl unless clse drect cntrl f tw measurements s essental. Whlst generally the subsdary measurement ranges are, sze fr sze, f the same rder, sme subsdary measurements have a reduced 2nd t 98th percentle range n the sngle cntrl sze-rll reference C. A further cmparsn f sngle- versus twn cntrl measurement sze-rlls may be made by studyng the Table 38 data n sze-rlls E and L and n sze-rlls G and M. Sze-rll E s a three-sze-rll based n head breadth as a sngle cntrl and sze-rll L s a sx-sze-rll based n twn cntrls, three range ntervals f head breadth and tw range ntervals f head length. Sze-rll G s a three-sze-rll based n head length as a 11

13 sngle cntrl and sze-rll M s a sx-sze-rll based n twn cntrls, three range ntervals f head length and tw range ntervals f head breadth. Frm ths cmparsn f pars f sngle and twn cntrl measurement sze-rlls, n whch the cmmn cntrl measurement s dvded nt three range ntervals, there s lttle evdence f any practcal advantage accrung frm the ntrductn f the secnd cntrl measurement apart frm the expected clser cntrl f the ranges f tw rather than ne measurement. Ths Reprt has assumed a practcal lmt f sx szes fr the twn cntrl sze-rlls cnsdered. Whlst t may be argued that ncreasng the twn cntrl sze-rlls t nne, 12 r 16 szes mght prve advantageus n cmparsn wth sngle cntrl sze-rlls f equvalent numbers f szes, there s lttle evdence, apart frm prvdng smaller ranges and magntude f the cntrl measurements, that ths wuld be the case wth the many ther subsdary measurements whch the headgear desgner may have t cnsder Szng Cntrl Measurements fr Encapsulatng Headgear n whch the Mentn (Chn) n ncluded wthn the Helmet Shell Fr purpses f analyss and cmparsn, all the sze-rlls cvered by ths Reprt nclude data whch prvde nfrmatn n the pstn f the mentn (chn) relatve t vertex (tp f head), back f head, and vertcal plane f brw lne (chn recessn r prtrusn frm brw lne). Sze-rlls referenced N, O and P, each f whch are twn cntrl sze-rlls, nclude a mentn lcatn measurement as ne f the cntrl measurements. The cntrl measurements f the fur-sze-rlls referenced N, O and P are : Sze-rll N---head breadth/mentn t vertex Sze-rll O--head breadth/mentn t back f head Sze-rll P head breadth/mentn t back f head mnus head length (chn recessn/prtrusn frm brw lne). Reference t the 2nd and 98th percentle data at Table 38 shws that use f sze-rlls N, O r P mpses penaltes by ncreasng the ranges f head crcumference and head length t be catered fr. Aganst these penaltes must be weghed the cnsderably reduced mentn lcatn measurement ranges where any f these s used as a cntrl measurement, and an asscated reductn f sme f these same measurements where they are nt cntrl measurements. Apart frm the abve mentn lcatn measurements, head crcumference and head length, the 2nd t 98th percentle ranges f all ther subsdary measurements fr sze-rlls N, O and P are very smlar t thse f the ther twn cntrl fur-sze-rlls. An exceptn t ths s the reduced pupl t vertex ranges asscated wth sze-rlls N and P. The use f sze-rlls N, O r P may be justfed by the headgear desgner f cntrl f mentn pstn, fr example fr lcatn n a padded hard-shell chn-cup, s an essental feature f the helmet desgn r f unnecessary dwnward r frward prtrusn f the chn-cup s undesrable. f such requrements are nt essental, cnsderatn shuld be gven t usng alternatve sze-rlls n whch a mentn lcatn measurement s nt utlsed as a cntrl measurement. t s apprecated that the takng f mentn lcatn measurements f the subject fr helmet fttng purpses wuld requre the servces f sklled persnnel and the use f a smple measurng rg. Hwever t s current practce n mltary avatn n the U.K. t emply sklled persnnel fr the fttug f all prtectve headgear.

Cncnusns () The specmen sze-rlls utlned n ths Reprt, whlst by n means cmprehensve n ther cverage f all pssble appraches, shuld prvde the desgner f mltary arcrew and ther types f headgear wth a,uller apprecatn f the relatnshp between the varus head measurements and the advantages and dsadvantages f the varus szng appraches fr specfc frms f headgear. () By prvdng quanttatve data fr 20 head measurements n each f the specmen sze-rlls at Tables 23 t 37 the nfrmatn n any sze-rll that meets the desgners requrements may be used drectly fr desgn purpses. () Whlst the verall cntrl measurement(s) ranges, frm whch the subsdary measurements data have been cmputed, have been determned by the authr, cnsderable lattude n the chce f subsdary measurement ranges has been prvded by the methd f presentatn f these data n Tables 23 t 37. (v) The penaltes ncurred n terms f the number, r percentage, f the 2000 arcrew survey ppulatn nt cvered by the specfc cntrl measurement ranges and selected subsdary measurement ranges fr any sze-rll may be determned readly frm the data prvded. 12

14 (v) The theretcal tarff f ndvdual szes f headgear wthn any f the cnsdered sze-rlls can be determned frm Tables 23 t 37. (v) The prmary am f ths Reprt s t prvde the headgear desgner wth numercal data n head measurements pertanng t varus appraches t headgear szng upn whch he can make judgement n the best practcal apprach t hs partcular prblems. Ths s regarded as a mre useful apprach than prvdng the desgner wth a theretcally best statstcal slutn t headgear szng whch may nt be the best practcal apprach fr all frms f prtectve headgear. (v) As the desgner's chce f methd f headgear szng may be determned by many factrs such as type f headgear, custmer's stpulatns regardng certan measurement cntrls, sze-rll tarff etc., n specfc recmmendatns regardng chce f sze-rll can be made. Hwever, brad gude lnes whch arse frm the presented data and the dscussn at Sectn 4 f ths Reprt ndcate that: (a) Sngle cntrl measurement sze-rlls shuld be used n preference t twn cntrl sze-rlls wherever practcable and, unless precse cntrl f head breadth r head length s requred, the best cmprmse slutn s t use head crcumference as the sngle-cntrl measurement n preference t head breadth r head length. (b) Wth sngle cntrl measurement sze-rlls an ncrease n the number f szes n the rll generally nly decreases the 'wthn sze' range and magntude f the cntrl measurement and has lttle practcal effect n the magntude r ranges f the subsdary measurements. Therefre, cnsstent wth meetng the cntrl measurement requrements, the mnmum number f szes shuld be adpted. (c) The advantage f usng twn cntrl measurement sze-rlls s a clse cntrl f tw head measurements rather than ne. Hwever, wth the arbtrary practcal lmt f a sx-sze-rll adpted n ths Reprt, the advantages are n sme cases margnal and shuld be gven serus cnsderatn befre adptn n preference t a sngle cntrl measurement sze-rll. (d) The use f twn cntrl measurement sze-rlls des nt generally reduce the magntude r range f subsdary measurements t be accmmdated when cmpared wth sngle cntrl sze-rlls f an equal number f szes. (e) There s lttle evdence that an ncrease n the number f szes f twn cntrl measurement sze-rlls t 9, 12, r 16 szes.e. thr~e r fur sub-grups f ether cntrl measurement, wuld have any majr effect n the subsdary measurement ranges t be accmmdated. t wuld f curse decrease the ranges and magntude f the cntrl measurements but at cnsderable lgstc and fnancal cst. (f) The use f twn cntrl measurement sze-rlls whch nclude ne mentn (chn) lcatn measurement may be justfed fr encapsulatng headgear n whch the chn s ncluded wthn the helmet hard shell.
