1.1 本实施规程描述了建立公差和根据规定标准评价样品颜色和光泽的程序。该实践适用于非荧光不透明样本。 1.2 本实践并不表明公差的范围，但给出了如何设置公差的指导。对于产品规格，样品与规定标准之间的公差应由买卖双方商定。 1.3 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.4 本国际标准是根据《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世界贸易组织技术性贸易壁垒委员会发布的建议。 ======意义和用途====== 5.1 颜色规格以颜色空间中的精确位置为中心。相应地，光泽规格以光泽标度上的精确位置为中心。因为很难重复地达到这些精确的位置，所以有必要指定买卖双方都能接受的公差。本实践详细介绍了实现这一目标的过程。

1.1 This practice describes a procedure for establishing tolerances and evaluating the color and gloss of specimens with respect to specified standards. This practice is appropriate for nonfluorescent opaque specimens. 1.2 This practice does not indicate the extent of tolerances, but gives guidance on how they can be set. For product specification, the tolerances between specimens and the specified standard should be agreed upon between the purchaser and the seller. 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 Color specifications are centered around exact positions in color space. Correspondingly, gloss specifications are centered around an exact position on the gloss scale. Because it is difficult to achieve these exact positions repeatedly, it is necessary to specify tolerances that are acceptable to both the buyer and the seller. This practice details the procedure for accomplishing this goal.
