1.1本规范规定了用于制备样品以评估各种基材上的涂层和衬里的尺寸、成分、表面处理和涂层应用变量。 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。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 4.1本规范规定了核电站涂层和衬里测试用试样制备的统一要求。 4.2用户可自行决定在制备待测试样品时使用本标准，以评估可能应用于其他类型发电厂或其他工业设施的涂层和衬里系统的性能属性。 4.3本指南的用户必须确保涂层工作不仅符合本指南，而且符合被许可方的工厂特定质量保证计划和许可承诺。

1.1 This specification defines the size, composition, surface preparation, and coating application variables for preparing samples for evaluating coatings and linings over various substrates. 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. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 4.1 This specification provides uniform requirements for the preparation of test samples used for testing of coatings and linings to be used in nuclear power plants. 4.2 At the users discretion, this standard may also be used when preparing samples to be tested for the purpose of assessing performance attributes for coating and lining systems that may be applied in other types of power plants or for other industrial facilities. 4.3 Users of this guide must ensure that coatings work complies not only with this guide, but also with the licensee’s plant-specific quality assurance program and licensing commitments.
