1.1 本试验方法涵盖了石油蜡中溶剂可提取物的测定。 1.2 以国际单位制表示的数值应视为标准。 1.2.1 例外-- 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====== 5.1 蜡中的溶剂可提取物可能对其若干性能产生显著影响，如强度、硬度、柔韧性、耐磨损性、摩擦系数、膨胀系数、熔点和染色特性。这些效果是可取的还是不可取的取决于蜡的预期用途。

1.1 This test method covers the determination of solvent extractables in petroleum waxes. 1.2 The values stated in SI units are to be regarded as standard. 1.2.1 Exception— 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 ====== 5.1 The solvent extractables in a wax may have significant effects on several of its properties such as strength, hardness, flexibility, scuff resistance, coefficient of friction, coefficient of expansion, melting point, and staining characteristics. Whether these effects are desirable or undesirable depends on the intended use of the wax.
