1.1 本规程涵盖了用于评估汽车抛光剂性能的测试性能和仪器。本规程适用于通常称为汽车蜡、清洁蜡、上光剂等的产品。 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 本规程旨在定义待测试的特性、使用的仪器以及产品性能的比较。众所周知，汽车抛光剂的配方制定者和营销者对其产品最重要的特性或性能特征有相当大的自由裁量权。这种做法足够灵活，可以在汽车抛光定义的范围内尊重这一事实。 4.2 这种做法的方法是主观和实证的，以符合行业的基本做法，并允许测试的灵活性。

1.1 This practice covers testing properties and apparatus used in evaluating the performance of automotive polishes. This practice is applicable to products that are commonly referred to as car/auto wax, cleaner wax, polish, etc. 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 This practice is intended to define the properties to be tested, the apparatus to use, and the comparisons of product performance. It is recognized that considerable discretion exists among formulators and marketers of automotive polish on what properties or performance characteristics are most important for their products. This practice is flexible enough to honor this fact within the confines of the automotive polish definition. 4.2 The methods of this practice are subjective and empirical in order to conform to the basic practices of the industry and to allow flexibility in testing.
