IEC 62598:2011适用于使用放射源（辐射计，以下简称辐射计）的电气测量系统和仪器的制造和安装。它也适用于用于上述测量系统的源外壳。本标准适用于与发电或燃料循环无关的设备。它规定了在辐射防护方面使用放射源的仪器设计的结构要求。本标准取消并取代IEC 60405。

IEC 62598:2011 applies to the manufacture and installation of electrical measuring systems and instruments utilizing radioactive sources (radiometric gauges, hereinafter called gauges). It also applies to source housings intended for use in the aforementioned measuring systems. This standard applies to equipment, which is not related to power production or to the fuel cycle. It specifies constructional requirements for the design of instruments utilizing radioactive sources in regard of radiation protection. This standards cancels and replaces IEC 60405.
