8、SO 9513 specifies that measurement uncertainty is to be stated. DIN EN ISO/IEC 17025 and the DAkkS-DKD-5 Guideline state that conformity can only be assumed if measurement uncertainty has been taken into account, that is, the error including uncertainty must lie within the given limits. Previously -

9、 when uncertainty did not have to be taken into account - it was sufficient to comply with the actual technical limits of the standard. Taking uncertainty into account may affect the classification of existing extensometer systems because the maximum permissible values have not been modified. One pr

10、actical means of taking uncertainty into account without negatively affecting the classification results is to use the newly defined criteria with permissible values of uncertainty given in Table A.1. In this way the entire range of the actual technical limits can still be applied. The DIN Standards

47、ystems involves a comparison of the readings given by the extensometer with known variations in length provided by a calibration apparatus.NOTE 1 The user can define the displacement range(s) over which the calibration is to be performed. In this way, the performance of the extensometer system can b

Hence, it would be appropriate, in this case, to concentrate the calibration on the centre portion of the operating range.The calibration process compares the known displacement from the calibration device with the output of the extensometer system. This output can range from manual readings of high precision dial gauges to the displacement indicat
