Lays down additional standard requirements concerning neutron flux measurements, temperature measurements, measurements on the coolant, and the protection system. The IEC 60231 series of standards is no longer up-to-date and will not be revised by IEC. The standards are maintained for the time being for bibliographical purposes and because they were used in the past for the design of nuclear power plants which are still in operation.
