1.1 这些试验方法包括确定变形量随时间的变化（蠕变试验），以及测量材料在恒定温度下承受恒定张力时，当存在足够的力（断裂试验）时发生断裂的时间。它还包括测试设备的基本要求。有关帮助确定理想测试次数和持续时间的信息，请参考产品规范。 1.2 这些测试方法列出了测试报告中应包含的信息。其目的是确保将所有有用且随时可用的信息传输给相关方。报告受到特别关注，原因如下: (1) 不同公认程序的结果差异显著；因此，识别使用的方法很重要； (2) 后期建立重要变量的研究往往因发表的报告中缺乏详细信息而受到阻碍； (3) 长期测试的性质往往使重新测试不切实际，同时也使其难以保持在某些受控变量的建议变化范围内。详细报告允许传输测试结果，而不暗示未达到的控制程度。 1.3 不包括缺口试样的试验。这些测试在实践中得到了解决 E292年 . 1.4 不包括短时条件下的试验。测试方法中介绍了这些测试方法 E21 . 1.5 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。 1.6 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、健康和环境实践，并确定监管限制的适用性。 1.7 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《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 适当解释的断裂试验提供了材料极限承载能力随时间变化的测量值。蠕变试验测量有限变形的承载能力。这两个测试在定义材料的承载能力方面相互补充。在选择材料和设计高温下使用的零件时，使用的测试数据类型将取决于负载标准- 更好地定义材料服务有用性的承载能力。

1.1 These test methods cover the determination of the amount of deformation as a function of time (creep test) and the measurement of the time for fracture to occur when sufficient force is present (rupture test) for materials when under constant tensile forces at constant temperature. It also includes the essential requirements for testing equipment. For information of assistance in determining the desirable number and duration of tests, reference should be made to the product specification. 1.2 These test methods list the information which should be included in reports of tests. The intention is to ensure that all useful and readily available information is transmitted to interested parties. Reports receive special attention for the following reasons: (1) results from different, recognized procedures vary significantly; therefore, identification of methods used is important; (2) later studies to establish important variables are often hampered by the lack of detailed information in published reports; (3) the nature of prolonged tests often makes retest impractical, and at the same time makes it difficult to remain within the recommended variations of some controlled variables. A detailed report permits transmittal of test results without implying a degree of control which was not achieved. 1.3 Tests on notched specimens are not included. These tests are addressed in Practice E292 . 1.4 Tests under conditions of short times are not included. These test methods are addressed in Test Methods E21 . 1.5 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. 1.6 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. 1.7 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. ====== Significance And Use ====== 4.1 Rupture tests, properly interpreted, provide a measure of the ultimate load-carrying ability of a material as a function of time. Creep tests measure the load-carrying ability for limited deformations. The two tests complement each other in defining the load-carrying ability of a material. In selecting material and designing parts for service at elevated temperatures, the type of test data used will depend on the criterion of load-carrying ability that better defines the service usefulness of the material.
