1.1 本规程涵盖了带电粒子辐照材料的机械试验性能。这些试验旨在了解中子辐照对材料力学性能的影响。描述了控制测试材料、粒子束、实验技术和损伤计算的实践。应参考其他ASTM标准，尤其是实践 第521页 描述了适用于在拉伸和扭转试验模式下进行的蠕变和蠕变断裂试验的程序。 2. 1.2 在这里，“模拟”一词的广义含义是指相关中子辐照环境的近似值。一致性程度可以从差到接近准确。 目的是在中子和带电粒子辐照的一个或多个方面之间产生对应关系，从而在辐照或材料参数与材料响应之间建立基本关系。 1.3 以国际单位制表示的值应视为标准值。本标准不包括其他测量单位。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。

1.1 This practice covers the performance of mechanical tests on materials being irradiated with charged particles. These tests are designed to provide an understanding of the effects of neutron irradiation on the mechanical behavior of materials. Practices are described that govern the test material, the particle beam, the experimental technique, and the damage calculations. Reference should be made to other ASTM standards, especially Practice E521 . Procedures are described that are applicable to creep and creep rupture tests made in tension and torsion test modes. 2 1.2 The word simulation is used here in a broad sense to imply an approximation of the relevant neutron irradiation environment. The degree of conformity can range from poor to nearly exact. The intent is to produce a correspondence between one or more aspects of the neutron and charged-particle irradiations such that fundamental relationships are established between irradiation or material parameters and the material response. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
