This International Standard establishes a method of classification of the information and command functions for nuclear power plants, and the I&C systems and  equipment that provide those functions, into categories that designate the importance to safety of the function. The resulting classification then determines relevant design criteria. The design criteria are the measures of quality by which the adequacy of each function in relation to its importance to plant safety is ensured. In this standard, the criteria are those of functionality, reliability, performance, environmental durability (including seismic) and quality assurance (QA).
