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 (<i>E<sub></sub></i><sub><i>n</i></sub>) values of 15 laboratories were within acceptable limits as per guidelines given by National Measurement Institute, Govt of India. <i>E</i><i><sub>n</sub> </i>values of 3 laboratories were found beyond the acceptable limit.
