1.1本试验方法涵盖了评估核电站所用涂层寿命辐射耐受性的标准程序。本试验方法适用于涂层服务水平I、II和III。 1.2以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 ====意义和用途====== 本试验方法旨在提供一种统一的试验，以评估核电设施中使用的涂层在设施寿命内的辐射暴露（包括DBA期间的辐射）的适用性（仅适用于涂层服务水平为I的区域）。 特定工厂辐射暴露可能超过或低于本标准7.2中规定的量。如果被许可方设计依据要求，使用的伽马剂量可能会超过实际预期电站伽马剂量，以计算β剂量。二级和三级区域（一级安全壳外）的涂层预计暴露在较低的累积辐射剂量下。

1.1 This test method covers a standard procedure for evaluating the lifetime radiation tolerance of coatings to be used in nuclear power plants. This test method is applicable to Coating Service Levels I, II, and III. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. ====== Significance And Use ====== This test method is designed to provide a uniform test to assess the suitability of coatings, used in nuclear power facilities, under radiation exposure for the life of the facilities, including radiation during a DBA (Coating Service Level I areas only). Specific plant radiation exposure may exceed or be less than the amount specified in 7.2 of this standard. If required by the licensee design basis, the gamma dose used may exceed the actual anticipated plant gamma dose to account for beta dose. Coatings in Level II and III areas (outside primary containment) are expected to be exposed to lower accumulated radiation doses.
