NB/T 20149-2012 in English

Scope

This standard specifies the test methods, test items and sequence for the qualification of pressure transmitters important for the safety of pressurized water reactor nuclear power plants (including positive and negative gauge pressure, differential pressure and absolute pressure), as well as testing and acceptance criteria during the test. This standard is applicable to the identification of pressure transmitters in pressurized water reactor nuclear power plants. It is not applicable to the software identification of intelligent pressure transmitters. It can be used as a reference when identifying pressure transmitters in other types of nuclear power plants.
