5 Report on Inter Laboratory Testing Scheme Preamble: Increasing awareness on textile quality and the buyer requirements are forcing textile manufacturers and traders to test quality of textile products from reputed laboratories. Reputation of any laboratory depends upon the result it produces. The test report given by any laboratory should be precise, accurate, repeatable and reproducible. This means, a set of results obtained within a laboratory by testing a representative sample at any time interval should be comparable. And also, the result obtained over testing a representative sample in any laboratory should be comparable with that of any other laboratory and fall within the statistical tolerance limit. In other words, the laboratory should be able to generate comparable results by performing the same test The repeatability and reproducibility of any test result involves the laboratory s competence in conducting the test which involves the testing equipment, the skill and knowledge of technical manpower working in the laboratory, the testing conditions and test method adopted. In this pursuit, the laboratory has to meet a requirement of maintaining its own management system as per ISO/IEC 17025:2005,to participate in Inter Laboratory Comparison (ILC) and/or Inter Laboratory Proficiency Testing Scheme (ILPT) Inter laboratory Comparison is defined by ISO/IEC as, Evaluation of participant performance against pre-established criteria by means of inter laboratory comparisons. The goal of the Inter-laboratory Comparisons (ILC) is to provide verification of each participating laboratory s technical capability by obtaining a measurement that agrees with all other Laboratories using different make & model of testing equipment and man-power. The requirement for inter laboratory comparisons remains in place today, and has been further entrenched into metrology management systems by its incorporation in the requirements of ISO/IEC 17025:2005 Textiles Committee: Textiles Committee is a statutory body under the Ministry of Textiles, Government of India, established in the year 1963 vide an act of parliament. The Committee has set up 16 laboratories throughout the country for catering to the testing requirements of the textile trade and industry. Fourteen laboratories of Textiles Committee are accredited as per ISO/IEC 17025:2005 by National Accreditation Board for testing & calibration Laboratories (NABL), India. Laboratory at Mumbai is the first in India to get accredited in the field of Textile Testing. All the laboratories of Textiles Committee have facilities to test mechanical and chemical test parameters. Nine laboratories of Textiles Committee have Eco testing facilities. By virtue of the Act, Textiles Committee develops many test standards and also adopts many national and international standards for testing purpose. PT-Provider: The Laboratory, Textiles Committee at Mumbai conducts as PT Provider, Inter Laboratory Proficiency Testing (ILPT) schemes for the benefit of Textile Testing laboratories. The national accreditation agency, NABL nominated laboratory of Textiles Committee at Mumbai, as nodal agency Page 3 of 42

6 for two ILPT schemes. The German Standards body, Physikalisch-TechnischeBundesanstalt (PTB), Germany recognized the schemes conducted by Textiles Committee and sponsored some laboratories of SAARC countries under its Quality Infrastructure Development Project (QIDP) in SAARC countries. Apart from India, laboratories from Bangladesh, Sri Lanka, Nepal, China, Hong Kong, Vietnam and USA also participate in the ILPT schemes conducted by Textiles Committee In order to offer ILPT schemes professionally as a PT Provider, the laboratory of Textiles Committee at Mumbai has implemented the Management System in accordance with the requirements stipulated in ISO/IEC 17043: The PT Provider has conducted 19 schemes since The details are given in Table 1 Table 1 ILPT schemes conducted by the PT Provider S.No Identity of the ILPT Year Field PT items No. of test parameters No. of participants 1 TC/ILTS/MECH/01/ Mechanical Fibre, Yarn & Fabric 2 TC/ILTS/CHEM/02/ Chemical Fabric TC/ILTS/MECH/03/ Mechanical Fabric TC/ILTS/CHEM/04/ Chemical Fabric TC/ILTS/MECH/05/ Mechanical Fabric TC/ILTS/MECH/06/ Mechanical Yarn TC/ILTS/MECH/07/ Mechanical Fibre TC/ILTS/CHEM/08/ Chemical Fabric TC/ILTS/CHEM/09/ Chemical Fabric TC/ILTS/CHEM/10/ Chemical Fabric TC/ILTS/MECH/11/ Mechanical Fabric TC/ILTS/CHEM/12/ Chemical Fabric TC/ILTS/Mech-1/ Mechanical Yarn & Fabric TC/ILTS/Chem-1/ Chemical Fabric and clothing accessory 15 TC/ILTS/15/Mech-2/ Mechanical Fabric TC/ILTS/16/Chem-2/ Chemical Fabric TC/ILTS/17/Mech-3/ Mechanical Cotton Fibre, 8 24 Sewing Thread 18 TC/ILTS/18/Chem-3/ Chemical Fabric TC/ILTS/19/Chem-4/ Chemical Extract and Fabric 2 30 The Present Programme: Design: In order to assess the reproducibility of the test results being reported by the various textile testing laboratories, this Proficiency Testing Scheme for Chemical testing - TC/ILTS/18/CHEM- 3/2015 was designed. The test parameters thus covered in the present PT Scheme and suggested test methods are given in Table 2. However, participants were required to use the test method Page 4 of 42

7 which is routinely adopted for the testing of regular samples. Hence, laboratories could adopt any equivalent standard or validated in-house method which is equivalent to the suggested standards.

Participants were instructed to identify the fibres in each direction separately and perform the overall blend composition of the fibres in the fabric adopting any method routinely used by them. (2) Fibre Identification and Composition by manual separation of fibres: Technical textile fabric made of Polyester in one direction and Cotton in other direction was procured from reputed trader and homogeneity test was carried out. Participants were instructed to identify the fibres in each direction separately and perform the overall composition of the fibres in the fabric adopting any method routinely used by them. (3) Colour Fastness Tests: Cotton dyed fabric was procured and homogeneity tests were carried out for different colour fastness tests viz (i) colour fastness to washing at 60 C with Soap and Soda [IS/ISO C10-(C3)], (ii) Colour fastness to light [ B02-method 3 and AATCC 16.3] and (iii) Colour fastness to Sea Water [IS 690]. Participants were required to report for washing at 60 C and Sea Water, along with Change in colour, staining on DW Multifibre Fabric, which has stripes of acetate, cotton, nylon, polyester, acrylic and wool. In case of fastness to light, Targeted Blue Wool Reference method [ B02-method 3] and Constant Exposure method [AATCC 16.3] were designed. Participants having computer colour matching system were given Page 6 of 42

9 opportunity to exhibit their competency in objective assessment by reporting Cartesian coordinates of Colour Space before and after exposure and the difference ΔE. Allotments of PT items: Allotments of PT items were done by following appropriate Sampling procedures adopted by using Random Numbers generated by computer, for Homogeneity testing, Stability testing and for distribution among participants. The remaining part of the population was kept as reserve for replacement in case of loss or damage. Henceforth, the allotted PT items can be referred as sample. Homogeneity testing: To verify the homogeneity of the prepared PT items homogeneity testing was conducted at the laboratory of Textiles Committee at Mumbai and Tirupur by the PT- Technical Manager. The procedure given in ISO 13528:2005 was followed for conducting homogeneity testing Dispatch of PT items: The Proficiency Testing items were dispatched to the respective participant laboratories on 16 th October 2015, along with the following: (a) Form for Acknowledging the receipt of PT items (b) Instructions to the participants in the Inter Laboratory Testing Scheme (c) Form for reporting test results by the participants in theinter Laboratory Testing Scheme The participant laboratories were requested to send the test results by 4 th November, However, as per request of participants and administrative reasons results were accepted after the due date. The participant laboratories were also requested to Treat the samples in the same manner as regularly tested samples and accordingly, codify the samples such that the technical staff testing them are not aware that they are meant for PT purposes; Adopt the latest test method which is routinely used by the laboratory for the testing of regular samples which may be any standard or validated in-house method; Forward (i) copy of the in-house method adopted (if applicable) for testing any parameter and also (ii) specify the standard method against which the validation has been done; and, Forward photo copy of Scope of accreditation certificate as a proof of accreditation for the test method adopted (applicable to accredited laboratories only). The participants were informed that, in the absence of proof of accreditation, the participant s value will not be considered for arriving at Assigned Value for the concerned test parameter, although, performance of the participant will be evaluated for this parameter. Further, it was also informed that the test results that may be inappropriate for statistical evaluation, for example, gross errors, miscalculations and transpositions may be excluded for calculation of summary statistics and performance evaluation of participants.

10 Compilation of the Test Results: In order to maintain the confidentiality of the participants of the PT Scheme, the individual participants were given Code numbers which are generated by using computer. Subsequently, the test results reported by the participants were tabulated and statistically analyzed for the basic statistics viz., Mean, Median, Mode, Maximum, Minimum, Standard Deviation, etc., While doing so, test results were checked for inappropriate for statistical evaluation, for example, gross errors, miscalculations and transpositions Determination Assigned Value: To ensure the measurement traceability, only accredited participants are considered for evaluating the Assigned Values. Thus due weightage is given to the accredited participants. That is, this weightage is given only when the participant had submitted their Scope of accreditation along with test results and accredited for the specific test in which the ILPT is conducted. However, when sufficient number of accredited participants is not available for any test, Assigned Value is derived from the consensuses from all participants for that parameter. Initially, the robust average and the standard deviation of values reported by the accredited laboratories (in respective tests) were determined for each parameter in accordance with the procedure given in ISO 13528: Subsequently, robust Z Score were calculated on the basis of the above. The test results of those laboratories which were found to be outliers (Z score more than +3 or less than -3) were deleted and Robust Average of the remaining expert laboratories was again calculated. This Robust average is treated as the assigned value for the concerned parameter In case of Ordinal test results, Mode of the values reported by accredited participant laboratories for that test is considered as Assigned Value. The Assigned Value of both the parameters thus arrived are given in Table 4. Determination of Standard Deviation for Proficiency Assessment (σ): The robust average and the robust standard deviation (σ 1 )of all qualified values reported by the participants were calculated for each of the test separately in accordance with the procedure given in ISO 13528:2005. Subsequently, the between-samples standard deviation (S S ) of homogeneity testing data was compared with the standard deviation of all the participants. If S S 0.3 σ 1, then the sample is considered as homogenous and the robust standard deviation of all the participants is treated as Standard Deviation for Proficiency Testing. That is σ= σ 1 If S S > 0.3 σ 1, then the sample is considered as heterogeneous and Standard Deviation for Proficiency Assessment is calculated by adding allowance for heterogeneity of the sample as stipulated in ISO 13528:2005, by using the formula Page 8 of 42

12 Evaluation of Participants: The performance of the individual participant was evaluated by adopting Robust Z score technique given in ISO 13528:2005, as per the following formula: Z x X where x is the test result reported by the individual participant; X is the Assigned Value and σ is the standard deviation of the Proficiency Assessment. In case of Ordinal test results the deviation of participant result by more than ½ grade compared to Assigned Value is taken as unsatisfactory (and outliers) and all other results are taken as satisfactory. Test wise performance evaluation is given in Annexure Interpretation of Comment: Table 5: Interpretation of comment Range of Laboratory Quantitative Results Z - Score 2 Satisfactory 2 < Z - Score < 3 Straggler Z - Score 3 Outlier Ordinal Results Reported Value Assigned Value ½ grade or 0.5 rating Reported Value - Assigned Value > ½ grade or 0.5 rating Satisfactory Outlier Outliers and Stragglers: Overall performance of all the participants is good. Stragglers and Outliers are very rare and far. The Outlier and Straggler Analysis is given in Table 6. General Advise to the participants on the performance: If a participant is found to be Outlier, necessary corrective action should be taken after thorough investigation of the root cause of the problem. Other (ADDITIONAL) Evaluation: Three participants (18007, and 18038) had carried out percentage composition of fibres in Group-2 by chemical dissolution method instead of manual separation. The results reported by these participants are evaluated separately and the evaluation is also included in this report. Page 10 of 42
