Standard Test Method for Rubber Chemicals—Density 橡胶化学品密度的标准试验方法
发布日期: 2021-11-01
1.1 本试验方法涵盖了在加工和制造过程中用作橡胶添加剂的固体化学品密度的测定。其旨在测定橡胶化学品本身的密度,而不是测定橡胶中化学品的有效密度。 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 橡胶化学品的密度用于计算橡胶化合物体积,该体积用于确定橡胶产品的成本。密度也可用作原材料控制工具。
1.1 This test method covers the determination of the density of solid chemicals used as rubber additives during processing and manufacture. It is intended for determining the density of the rubber chemical itself and not for the determination of the effective density of the chemical in a 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 The density of a rubber chemical is used for calculating the rubber compound volume, which is used to determine the cost of a rubber product. The density may also be used as a raw material control tool.
