1.1 本试验方法包括通过测量下落质量的垂直回弹来测定固体橡胶的冲击回弹性。 1.2 本试验方法不适用于多孔橡胶或涂层织物的试验。 1.3 测试方法中描述了通过回弹摆对橡胶的冲击回弹性和穿透性的标准测试方法 D1054 . 1.4 以SI单位表示的值应被视为标准。括号中给出的值仅供参考。 1.5 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。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法规限制的适用性。 1.6 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》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 4.1 弹性是橡胶的动态模量和内部摩擦的函数。它对温度变化和柱塞的穿透深度非常敏感。因此，通常不能从另一种类型的回弹仪器的结果预测来自一种类型的回弹仪器的弹性值。 4.2 该测试方法用于材料的开发和比较。它可能与最终用途性能没有直接关系。

1.1 This test method covers the determination of impact resilience of solid rubber from measurement of the vertical rebound of a dropped mass. 1.2 This test method is not applicable to the testing of cellular rubbers or coated fabrics. 1.3 A standard test method for impact resilience and penetration of rubber by a rebound pendulum is described in Test Method D1054 . 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 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. 1.6 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 Resilience is a function of both dynamic modulus and internal friction of a rubber. It is very sensitive to temperature changes and to depth of penetration of the plunger. Consequently, resilience values from one type of rebound instrument may not, in general, be predicted from results on another type of rebound instrument. 4.2 This test method is used for development and comparison of materials. It may not directly relate to end-use performance.
