1.1 这些试验方法涵盖了炭黑灰分含量的测定。 1.2 以国际单位制表示的数值应视为标准。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）。本标准的使用者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。 有关具体的预防说明，请参阅第节 6. 和 13 . 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《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 炭黑的灰分含量是燃烧后存在的非碳成分的量。灰分的主要贡献者是制造工艺用水和原料中的催化剂。

1.1 These test methods cover the determination of the ash content of carbon black. 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. For specific precautionary statements see Sections 6 and 13 . 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 ash content of a carbon black is the amount of non-carbon components present after combustion. Primary contributants to ash are the manufacturing process water and the catalyst in the feedstock.
