1.1 这些试验方法包括母料中炭黑含量的测定，以及乳液SBR炭黑混合物，但也适用于其他聚合物。包括三种测试方法: 章节 惰性气氛热解 3- 10 真空热解 11– 17 热重分析仪 18- 24 注1: 这些试验方法中使用的命名法符合规程 D1418 。 1.2 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。 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。 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 如果惰性（CO 2. )大气和确定性 注2 )已知炭黑含量的炭黑是可用的。 注2: 可通过在研磨机上小心添加准确量的橡胶和炭黑来制备确定的黑色母料。 另一种选择是彻底混合一定量的黑色母料，并使用先前确定的测定方法测定炭黑。

1.1 These test methods cover the determination of the amount of carbon black in a masterbatch and cover emulsion SBR-carbon black mixtures, but may be applicable to other polymers. Three test methods are included: Sections Inert Atmosphere Pyrolysis 3 – 10 Vacuum Pyrolysis 11 – 17 Thermogravimetric Analyzer 18 – 24 Note 1: The nomenclature used in these test methods is in accordance with Practice D1418 . 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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 carbon black content of an unvulcanized black or oil-black SBR masterbatch may be determined by this test method if an inert (CO 2 ) atmosphere and a determinate (see Note 2 ) of known carbon black content are available. Note 2: Determinate black masterbatch may be prepared by careful addition of exact amounts of rubber and carbon black on a mill. An alternative would be a thorough blending of a quantity of black masterbatch and determination of the carbon black by use of a previously established determinate.
