1.1 本规程为平板、镀膜和未镀膜玻璃颜色的仪器反射率测量提供了指南。（参见术语 E284年 .) 1.2 本规程特别排除荧光和彩虹色样品。 1.3 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。 1.4 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。 1.5 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 颜色测量量化了玻璃的涂层颜色，通常与涂层厚度和成分以及基板玻璃中使用的着色有关。本文件的用户定义了适用于最终用途的可接受颜色范围。 镀膜玻璃产品反射色测量的典型质量问题是涂层过程中的一致性指示，以及验证批次间的颜色一致性以供最终用户验收。 4.2 如果玻璃产品的反射颜色在不同批次之间一致，并且在商定的供应商-买方验收标准范围内，则该产品的颜色应一致，并可用于最终用途。

1.1 This practice provides guidelines for the instrumental reflectance measurement of the color of flat, coated and uncoated glass. (See Terminology E284 .) 1.2 The practice specifically excludes fluorescent and iridescent samples. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. 1.5 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 Color measurement quantifies the coating color for glass and is often related to coating thickness and composition as well as tinting used in the substrate glass. The user of this document defines an acceptable range of color appropriate for the end use. Typical quality concerns for the reflected color measurement of coated glass products are an indication of consistency in the coating process and verification of lot-to-lot color consistency for end-user acceptance. 4.2 If the reflected color of a glass product is consistent from lot-to-lot and within agreed supplier-buyer acceptance criteria, that product color is expected to be consistent and acceptable for end-use.
