1.1 本试验方法包括通过在酸化浓盐溶液上提取未分解的磺化或硫酸化脂肪和其他脂肪物质，测定磺化或硫酸化油或两者样品中的总活性成分。不包括游离碱或碱结合肥皂。本试验方法源自试验方法 D500 . 注1: 仅在硫酸化油的情况下，也可通过计算估算该测定值（见 6.3 )，因为它相当于脱硫脂肪物质和中和的有机结合硫酸酐的总和。 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====== 3.1 本试验方法旨在测定磺化油和硫酸化油中所含的总活性成分。不包括游离碱和碱性肥皂。

1.1 This test method covers the determination of the total active ingredients in a sample of sulfonated or sulfated oil, or both, as it exists in the original sample by extracting the undecomposed sulfonated or sulfated fat and other fatty matter over an acidified concentrated salt solution. Free alkali or alkali bound as soap is not included. This test method was derived from Test Methods D500 . Note 1: In the case of sulfated oils only, this determination may also be estimated by calculation (see 6.3 ), as it is equivalent to the sum of the desulfated fatty matter and neutralized organically combined sulfuric anhydride. 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 ====== 3.1 This test method is intended for the determination of the total active ingredients contained in sulfonated and sulfated oils. Free alkali and alkaline soaps are excluded.
