1.1 本规范涵盖称为海绵橡胶和膨胀橡胶的柔性多孔橡胶产品，但不适用于乳胶泡沫橡胶或硬质多孔橡胶。开/闭式泡沫产品的基材可以由合成、天然或再生橡胶或混合物制成，并且可以包含其他聚合物或化学品，或两者，可以通过有机或无机添加剂进行改性。这些弹性材料具有与硫化橡胶相似的特性，即（1）通过交联（硫化）从热塑性状态转换为热固性状态的能力，或（2）在拉伸或拉长时，或两者兼而有之时，其原始形状的实质性恢复。 1.2 尺寸太小，无法切割标准试样的挤压或模制形状很难用这些方法进行分类或测试，通常需要特殊的测试程序。 1.3 如果本通用规范的规定与特定产品的详细规范或测试方法的规定相冲突，应以后者为准。参考本规范中的测试方法时，应特别说明所需的一个或多个特定测试。 1.4 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。 1.5 以下安全隐患警告仅适用于本规范的测试方法部分: 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。 注1: ISO 6916-1与本规范类似。 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》中确立的国际公认标准化原则制定的。

1.1 This specification covers flexible cellular rubber products known as sponge rubber and expanded rubber, but does not apply to latex foam rubber or ebonite cellular rubber. The base material for an open/closed cellular product may be made of synthetic, natural, or reclaimed rubber, or a mixture, and may contain other polymers or chemicals, or both, which may be modified by organic or inorganic additives. These elastomeric materials have properties similar to those of vulcanized rubber, namely (1) the ability to be converted from a thermoplastic to a thermosetting state by crosslinking (vulcanization) or (2) the substantial recovery of their original shapes when strained or elongated, or both. 1.2 Extruded or molded shapes of sizes too small for cutting standard test specimens are difficult to classify or test by these methods and will usually require special testing procedures. 1.3 In case of conflict between the provisions of this general specification and those of detailed specifications or test methods for a particular product, the latter shall take precedence. Reference to the test methods in this specification should specifically state the particular test or tests desired. 1.4 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. 1.5 The following safety hazards caveat pertains only to the test methods portions of this specification: 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. Note 1: ISO 6916-1 is similar to this specification. 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.
