特别是涉及中子注量率、燃料温度、冷却剂温度和流量的测量设备，以及保护系统。 IEC 60231系列标准不再是最新的，IEC不会对其进行修订。目前保留这些标准是为了参考书目，因为它们过去曾用于仍在运行的核电厂的设计。

Deals more particularly with the measuring equipment for fluence rate of neutrons, fuel temperature, coolant temperature and flow, and with 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.
