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.
