1.1 本指南引导用户完成建立颜色规范的过程，包括目标颜色和允许公差。它指的是适当的ASTM标准，该标准更全面地描述了过程的每个步骤，从预期开始，包括过程中的注意事项，最后以报告结束。 1.2 本指南不建议公差的数值。这些值必须由相关各方商定。 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====== 5.1 由于颜色导致的材料拒收是一种常见且昂贵的情况，客户和生产商在交易前设置具有相关公差的颜色规格非常有用。本指南讨论了该概念，并详细介绍了该过程中使用的ASTM标准。

1.1 This guide leads the user through a process for establishing color specifications, including the target color and allowable tolerances. It refers to the appropriate ASTM standards that more thoroughly describe each step of the process beginning with expectations, encompassing caveats within the process and finally concluding with reporting. 1.2 This guide does not suggest numerical values for tolerances. These values must be agreed upon by the parties involved. 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 The rejection of materials due to color is a common and expensive occurrence, and it is useful for a customer and producer to set color specifications with an associated tolerance before the transaction. This guide discusses the concept and details the ASTM standards to be used in the process.
