This standard specifies the test methods, test items and sequence, test and acceptance criteria during the test period for the qualification of the pressure transmitter important to safety of nuclear power plants (including positive, negative gauge pressure, differential pressure and absolute pressure). This standard is applicable to the qualification of pressure transmitters for PWR nuclear power plants, not to the software qualification of intelligent pressure transmitters. The pressure transmitter of other types of nuclear power plant may refer to this standard.

Summary
This standard specifies the test methods, test items and sequences for the safety of important pressure (including positive, negative pressure, differential pressure and absolute pressure) of the PWR nuclear power plant safety test and acceptance criteria during the test. This standard is applicable to the identification of Dongli transmitter of PWR nuclear power plant. It is not suitable for the identification of intelligent pressure transmitter. Other types of nuclear power plant can be used when referring to pressure transmitter.
