1.1 本试验方法包括比较水乳液地板抛光剂中乳化颗粒沉积的薄膜（或固体）的颜色。它基于使用三刺激色度计（如Hunter色差计）进行的发光反射率测量。 2. 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====== 5.1 从滤纸上夸张的干燥抛光膜的反射率测量获得的白度指数可以用作这种膜的颜色的测量。 5.2 白度指数可用于预测抛光膜对地板基材的潜在变色效果。 5.3 当用标准样品抛光剂进行颜色比较时，白度指数在规范中应该很有用。

1.1 This test method covers comparing colors of films (or solids) deposited from the emulsified particles in water emulsion floor polishes. It is based upon luminous reflectance measurements made with tristimulus colorimeters such as the Hunter Color Difference Meter. 2 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 ====== 5.1 Whiteness index obtained from reflectance measurements on exaggerated dried polish films on filter paper can be used as a measurement of the color of such films. 5.2 Whiteness index may be useful in predicting the potential discoloring effect of polish films on flooring substrates. 5.3 Whiteness index should be useful in specifications when color comparisons are made with a standard sample polish.
