1.1 本试验方法涵盖了测定合成橡胶中灰分含量的试验方法。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 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。 1.4 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 这些测试主要用于裁判目的，但也可用于橡胶生产的质量控制。 4.2 橡胶的总灰分和水溶性灰分含量会影响复合硫化橡胶的性能，如吸水性、膨胀性、电性能等。

1.1 This test method covers a test method for the determination of ash content in synthetic rubber. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. 1.4 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 These tests are mainly intended for referee purposes but can also be used for quality control of rubber production. 4.2 The total and water soluble ash content of a rubber can affect the properties of compounded, vulcanized rubber such as water absorption, swell, electrical properties, etc.
