尤其适用于压水反应堆的仪表。特别涉及中子注量率（通量）的测量。 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。

Applicable more particularly to instrumentation for pressurized water reactors. Deals in particular with measurements of neutron fluence rate (flux). 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.
