2 Permanent Laboratory quantity / Coordinate measuring technology Prismatic workpieces Coordinate measuring machines with a calibrated measuring volume of: X = 1800 mm Y = 1000 mm Z = 600 mm Balls Large diameter to 50 mm Tactile measurement in the form of single-points measurements using a calibrated coordinate measuring machine and determination of geometric parameters defined through control geometries (single points, straight lines, planes, circles, balls, cylinders, tapers, toroids) using the evaluation software of the machine Single-point measuring can be carried out either with fixed, predefined measuring force or with extrapolation on measuring force zero. Single-point measurements in the form of Self-centring measurements are not used within the framework of the accreditation The calibration values can be determined in a multilayer process by centering in order to reduce the measurement uncertainty Substitution measurement on a calibrated machine with tactile single-point measurement capability determined using the machine method based on VDI/VDE 2617 part 7:2008 through simula-tion is specific to each task and is started through multiplication of the standard uncertainty by a coverage factor k = 2 The use of the multilayer method refers to the mean value determined simulated measurement uncertainty for bidirectional length measurement uncertainties on steel artefacts in measuring positions according to DIN EN ISO :2010 in the specified measurement volume for central styluses (zero clearance between centre of the ball center and the spindle axis): UE0 = 0,8 µm + 2, L and for measurements with lateral styluses (150 mm clearance between centre of the ball center and the spindle axis) maximum: UE150 = + 2, L 0,3 µm L = measured length Calibration in the DAkkS calibration laboratory only determined for general measurement tasks within the framework of the accreditation is specific to each task and can therefore differ significantly from the stated length measurement uncertainty The declared uncertainty which is given here is only valid as an example for the described simple measuring tasks For general measuring tasks reffered to the accreditated scope the measuring uncertainty could be significant differenty Period of validity: to Translation - Page 2 of 6
