1.1 本指南涵盖了确定影响电泳涂料性能的重要参数的试验方法的选择。 1.2 涉及的测试方法包括 D4370 , D4399 , D4584 ，以及 D5145 . 1.3 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====== 3.1 本指南说明了在电泳浴中保持油漆可接受性能的推荐测试程序。在整个浴槽操作过程中，必须确定几个关键参数。当出现偏离规范的情况时，必须调整这些参数。 3.2 电泳浴的测试方法是独特的，因为水性样品的不挥发物含量在8%至25%之间。在取样和测量某些参数时，必须持续搅拌。

1.1 This guide covers the selection of test methods for determination of the important parameters that affect the performance of electrocoating paints. 1.2 The test methods involved are D4370 , D4399 , D4584 , and D5145 . 1.3 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 ====== 3.1 This guide indicates test procedures recommended for the maintenance of acceptable performance of the paint in an electrocoating bath. Several critical parameters must be determined throughout the operation of the bath. These parameters must be adjusted when deviations from the norm occur. 3.2 The test methods for electrocoat baths are unique, as the aqueous samples have a nonvolatile content between 8 % and 25 %. Constant agitation must be present when the samples are taken and during the measurement of some of the parameters.
