1.1本试验方法包括使用固特异希利回弹摆测定橡胶的冲击回弹和渗透性，见图1。 1.1.1本方法中使用的术语橡胶应指分类为热塑性弹性体、硫化（热固性）橡胶、弹性材料和多孔材料的物质。 1.2用于测定质量、力、方向、温度或尺寸的所有材料、仪器或设备应可追溯至国家标准与技术研究所或其他国际公认的平行组织。 1.3以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。国际单位制中的许多规定尺寸是从美国习惯系统直接转换而来的，以适应1975年《公制转换法》之前存在的仪器、惯例和程序。 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====== 固特异希利 3. 回弹摆用于测量橡胶化合物的回弹百分比，作为滞回能量损失的指示，滞回能量损失也可以由储能模量和损耗模量之间的关系来定义。测量的回弹百分比与滞后损失成反比。 通过测量回弹球穿透被测橡胶块的深度来确定挠度。 回弹率和挠度通常用于聚合物和复合化学品（尤其是增强材料）的质量控制测试。

1.1 This test method covers the determination of impact resilience and penetration of rubber by means of the Goodyear-Healey rebound pendulum, see Fig. 1. 1.1.1 The term rubber, used within this method, shall refer to those substances classified as thermoplastic elastomers, vulcanized (thermoset) rubber, elastomeric materials, and cellular materials. 1.2 All materials, instruments, or equipment used for the determination of mass, force, direction, temperature or dimension shall have traceability to the National Institute for Standards and Technology, or other internationally recognized organization parallel in nature. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. Many of the stated dimensions in SI are direct conversions from the U.S. Customary System to accommodate the instrumentation, practices and procedures that existed prior to the Metric Conversion Act of 1975. 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 ====== The Goodyear-Healey 3 rebound pendulum is designed to measure percent resilience of a rubber compound as an indication of hysteretic energy loss that can also be defined by the relationship between storage modulus and loss modulus. The percent rebound measured is inversely proportional to the hysteretic loss. Deflection is determined by measuring the depth of penetration of the rebound ball into the rubber block under test. Percent resilience and deflection are commonly used in quality control testing of polymers and compounding chemicals, especially reinforcing material.
