1.1 本试验方法用于通过仪器失重技术快速测定非挥发性（固体）含量的重量百分比。它并不意味着替代试验方法 第2369页 . 1.2 该测试方法主要适用于质量控制实验室和制造环境，在这些环境中，先前表征的材料将针对不同批次或批次进行重复测试。 1.3 本试验方法可用于水性和溶剂性树脂、中间体和成品油漆。该测试方法可能不适用于所有类型的涂层。 1.4 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。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如有）。 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，并确定监管限制的适用性。 注1: 没有类似或等效的ISO标准。 1.6 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 本试验方法旨在用作快速质量控制、验收和评估试验。大多数材料的结果在五到十五分钟内得到。由于调整了仪器参数以产生与试验方法相同的结果 第2369页 当对同一材料的不同批次或批次进行大量测量时，使用该仪器方法确定涂层测试的最佳条件所花费的时间和精力非常宝贵。此外，测量和计算的自动化应能减少训练有素的操作员犯下的错误。

1.1 This test method is used to obtain rapid determination of the weight percent nonvolatile (solids) content via instrumental loss in weight technology. It is not meant as a replacement for Test Method D2369 . 1.2 This test method is principally intended for quality control labs and manufacturing environments where previously characterized materials will be tested repeatedly for different batches or lots. 1.3 This test method can be used for waterborne and solventborne resins, intermediates and finished paint products. This test method may not be applicable to all types of coatings. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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. Note 1: There is no similar or equivalent ISO standard. 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 ====== 5.1 This test method is intended for use as a rapid quality control, acceptance, and assessment test. Results are obtained in five to fifteen minutes on most materials. Since the instrument parameters are adjusted to produce the same results as Test Method D2369 , which takes over one hour to run, the time and effort expended on determining the optimal conditions for testing a coating with this instrumental method is valuable when numerous measurements are going to be made on different lots or batches of the same material. Also, the automation of the measurement and the calculations should lead to fewer mistakes being made by less-trained operators.
