Abstract: Proficiency testing of pressure measurement was carried out among 21 laboratories using digital pressure calibrator. Total 178 pressure measurements (pressure range, 7-70 MPa) were recorded at 10 equally spaced pressure points. Normalized error (En) values of 15 laboratories were within acceptable limits as per guidelines given by National Measurement Institute, Govt of India. En values of 3 laboratories were found beyond the acceptable limit.
