Abstract: Main variations of a new Pressure Transducer (Static) Verification Regulation JJG 860-2015 are introduced. Discussions are carried out on the selection of the test instruments and the verification methods for specific pressure transducers. The necessity of adding two new performance indicators, the zero shift and the cycle stability, is demonstrated according to some test cases. Furthermore, some improvement suggestions for this regulation are proposed.

Key words: Pressure transducer, Zero shift, Cycle stability
