1.1 本试验方法涵盖了对薄膜干涉颜料进行仪器颜色测量所需的仪器要求和所需参数。本试验方法旨在涵盖建筑应用、汽车、涂料、化妆品、油墨、包装、油漆、塑料、印刷、安全和其他应用中使用的干扰颜料。 1.2 用干涉颜料着色的材料的光学行为的表征需要在多个照明和检测角度进行测量。 1.3 利用本试验方法获得的数据是定量的，适用于干扰颜料颜色的质量控制。 1.4 测量结果通常表示为反射因子、三色刺激值或CIE L*a*b*颜色坐标和色差。 1.5 评估也含有非干扰颜料的混合物时，可能不需要获得全部数据。委员会正在调查和评估该测试方法对这些材料的适用性。用户有责任确定本试验方法对其特定应用的适用性。 1.6 干扰颜料通常用于评估介质（如油漆或油墨）中的颜色和颜色外观。视在效应很大程度上取决于介质的物理和化学性质。影响颜色和颜色外观的一些特性包括车辆粘度、厚度、透明度和体积固体。一般来说，出于质量控制目的，干扰颜料最好以masstone产品形式进行评估。在某些情况下，该产品形式可能是最终产品形式，或更典型的是预期产品形式的合格模拟（如油漆缩尺），其颜色和外观与最终产品应用相关。 1.7 本标准不涉及对含有金属薄片颜料的材料进行表征的要求。试验方法中描述了含有金属薄片颜料的材料的光学特性测量 E2194年 . 1.8 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。 1.9 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。 1.10 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====== 5.1 本试验方法旨在提供从干扰颜料在特定照明和检测角度下的光谱反射率因子获得的颜色数据。 本试验方法中提供的信息基于仅用干扰颜料着色的材料的数据。 5.2 这些数据可用于验收测试、设计、研究、制造控制和质量控制。 5.3 样本必须在统计学上代表最终用途。 5.4 用户应确认本试验方法对其他材料的适用性，包括干扰颜料与吸收和散射颜料的组合。

1.1 This test method covers the instrumental requirements and required parameters needed to make instrumental color measurements of thin film interference pigments. This test method is designed to encompass interference pigments used in architectural applications, automobiles, coatings, cosmetics, inks, packaging, paints, plastics, printing, security, and other applications. 1.2 Characterization of the optical behavior of materials colored with interference pigments requires measurement at multiple angles of illumination and detection. 1.3 Data taken utilizing this test method are quantitative and are appropriate for quality control of interference pigment color. 1.4 The measurement results are usually expressed as reflectance factors, tristimulus color values, or as CIE L*a*b* color coordinates and color difference. 1.5 The totality of data taken may not be necessary for evaluating mixtures also containing non-interference pigments. The committee is investigating and evaluating the appropriateness of this test method for those materials. It is the responsibility of the users to determine the applicability of this test method for their specific applications. 1.6 Interference pigments are typically evaluated for color and color appearance in a medium, such as paint or ink. The gonioapparent effect depends strongly on the physical and chemical properties of the medium. Some of the properties affecting color and color appearance include vehicle viscosity, thickness, transparency, and volume solids. As a general rule, for quality control purposes, interference pigments are best evaluated in a masstone product form. In some cases this product form may be the final product form, or more typically a qualified simulation of the intended product form (such as a paint drawdown) that in terms of color and appearance correlates to final product application. 1.7 This standard does not address the requirements for characterizing materials containing metal flake pigments. Measurements of the optical characteristics of materials containing metal flake pigments are described in Test Method E2194 . 1.8 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.9 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. 1.10 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 This test method is designed to provide color data obtained from spectral reflectance factors at specific illumination and detection angles for interference pigments. Information presented in this test method is based upon data taken on materials exclusively pigmented with interference pigments. 5.2 These data can be used for acceptance testing, design purposes, research, manufacturing control, and quality control. 5.3 Specimens must be statistically representative of the end use. 5.4 Applicability of this test method for other materials, including combining interference pigments with absorbing and scattering pigments should be confirmed by the user.
