scope:

This standard provides the nuclear power industry methods for assuring that nuclear safety-related instrument channels satisfy acceptable calibration, response time, and other factors affecting the performance of the instrument channel. This standard applies only to those instrument channels whose primary sensors measure pressure, differential pressure, temperature, or neutron flux. Primary flow elements are addressed by other standards.

Purpose

The purpose of this standard is to provide guidance to the nuclear power industry in demonstrating acceptable performance of safety-related instrument channels.
