1.1 这些测试方法包括通过测定无机颜料含量的不挥发物含量来表征电泳槽。 1.2 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。 1.3 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====== 4.1 不挥发物含量和颜料含量分别是对电泳涂料中总固体和无机颜料固体的测量。除了生产质量控制外，这些性能对于将电泳槽保持在最佳范围内也很重要。 4.2 指南中描述了测定油漆和油漆相关材料不挥发物含量的其他试验方法 D2832 .

1.1 These test methods cover the characterization of electrocoat baths through the determination of nonvolatile content of inorganic pigment content. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 ====== 4.1 The nonvolatile content and pigment content are measures of total solids and inorganic pigment solids, respectively, in electrocoat paints. In addition to production quality control, these properties are important in maintaining electrocoat baths in the optimum range. 4.2 Other test methods for determining nonvolatile content of paint and paint related materials are described in Guide D2832 .
