1.1 本指南涵盖了涂层粉末和粉末涂料测试程序的选择和使用。所包含的测试方法列于 表1 如果为同一特性列出了多种测试方法，则不试图表明一种方法优于另一种方法。选择要遵循的方法必须由经验和每个案例的要求以及买方和卖方之间的协议来决定。 1.2 本指南还涉及粉末涂料协会（PCI）和国际标准化组织（ISO）专门为涂料行业开发的方法。 1.3 本指南描述了通过静电喷雾、流化床或任何其他适用方法施加的涂层粉末的测试。 1.4 以国际单位制表示的值应被视为标准值。本标准不包括其他计量单位。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。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，并确定监管限制的适用性。 1.6 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====== 4.1 本指南为涂层粉末和粉末涂料测试程序的选择和使用提供了有用的总结。除非另有说明，否则它适用于热塑性和热固性涂料。根据设计，本指南并不旨在解决专门为功能性粉末涂料市场开发的测试方法或程序，即用于管道或钢筋（钢筋）的涂料粉末。关于管道和钢筋涂层粉末和粉末涂层的当前测试程序的信息，可以通过各自的ASTM小组委员会A01.05和D01.48获得。 4.2 选择要遵循的方法和解释结果必须由经验和每个案例的要求以及买卖双方之间的协议来决定。 应该指出的是，用于表征涂料粉末的许多方法，如凝胶时间（第 16 )斜流（断面 17 )，主要用于两种涂层粉末的相对比较，而不是给出可以解释为好或坏的测试值。测试结果的解释将取决于所讨论的具体应用，也通常取决于所用涂料粉末的化学性质。

1.1 This guide covers the selection and use of procedures for testing coating powders and powder coatings. The test methods included are listed in Table 1 . Where more than one test method is listed for the same characteristic, no attempt is made to indicate superiority of one method over another. Selection of the methods to be followed must be governed by experience and the requirements in each individual case, together with agreement between the purchaser and the seller. 1.2 This guide also refers to methods developed specifically for the coating powder industry by the Powder Coating Institute, PCI, and the International Organization for Standards, ISO. 1.3 This guide describes the testing of coating powders as applied by electrostatic spray, fluidized bed, or any other applicable method. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. 1.6 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 This guide provides a useful summary to the selection and use of procedures for testing coating powders and powder coatings. It is applicable to both thermoplastic and thermoset coatings, unless indicated otherwise. By design this guide does not purport to address test methods or procedures developed specifically for the functional powder coating market, those coating powders for application to pipe or reinforced steel bars (rebar). Information on current test procedures for pipe and reinforced steel bar coating powders and powder coatings can be obtained through their respective ASTM Subcommittees, A01.05 and D01.48. 4.2 Selection of the methods to be followed and the interpretation of results must be governed by experience and the requirements in each individual case, together with agreement between the purchaser and seller. It should be noted that many of the methods used for characterizing a coating powder, such as gel time (Section 16 ) and inclined flow (Section 17 ), are primarily meant for the relative comparison of two coating powders, rather than to give a test value that can be interpreted as good or bad. Interpretation of the test results will depend on the specific application in question and will also often depend on the chemistry of the coating powder used.
