文摘

We report the performance of calibration laboratories in the pneumatic pressure region (0 to 5) MPa through a recently conducted inter-laboratory comparison. Six NABL (National Accreditation Board for Testing and Calibration Laboratories) accredited laboratories participated in the program. The proficiency testing program was organized and piloted by CSIR-National Physical Laboratory. The program started in June 2010 and was completed in October 2011. The artifact used was a high precision pressure dial gauge. The reference values were generated by the pilot laboratory. The deviations for each participating laboratory were estimated against the reference pressure values and the compatibility of the results was calculated using the conventional method. Out of the total measurements made, all but two were found to be in good agreement with the reference values. The normalized error values (E n) of five laboratories out of the total six were found well within?±?1 over the entire pressure range.
