GB/T 8993-1998 in English

本标准规定了核仪器环境条件的分级、分类、分组、严酷等级和环境试验方法。本标准适用于实验室核仪器、同位素与辐射应用核仪器、放射性探矿与选矿核仪器、医用核仪器、核反应堆仪器和辐射防护仪器。本标准规定的核仪器环境条件的分组和试验方法是制定核仪器产品标准和有关文件中的环境试验条件和试验方法的依据。核仪器在规定环境条件下的性能要求不属本标准范围，由有关产品标准规定。超出本标准规定的应用环境条件和试验方法应由用户和厂家根据有关的产品标准协商解决。本标准不适用于核电厂安全级(1E级)核仪器。不能进行整机试验的设备，可分别进行分体试验。

Scope

This standard specifies the classification, classification, grouping, severity level and environmental test methods of environmental conditions of nuclear instruments. This standard applies to laboratory nuclear instruments, isotope and radiation application nuclear instruments, radioactive mineral prospecting and mineral processing nuclear instruments, medical nuclear instruments, nuclear reactor instruments and radiation protection instruments. The grouping and test methods of nuclear instrument environmental conditions specified in this standard are the basis for formulating environmental test conditions and test methods in nuclear instrument product standards and related documents. The performance requirements of nuclear instruments under specified environmental conditions are not within the scope of this standard, and are regulated by relevant product standards. Application environment conditions and test methods beyond the provisions of this standard should be resolved through consultation between the user and the manufacturer according to the relevant product standards. This standard does not apply to nuclear instruments of safety level (level 1E) in nuclear power plants. For equipment that cannot be tested as a whole, separate tests can be performed separately.
