1.1 本试验方法包括使用市售设备测定电泳浴或超滤液样品的电导率。 1.2 以国际单位制表示的数值应视为标准。本标准中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）。本标准的使用者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 电涂层浴的导电性是由于浴中存在来自载体的离子物质，以及以可离子化的酸、碱、盐或这些物质的组合形式存在的杂质。过量离子杂质的存在对电涂涂料的应用和性能是有害的。该测试适用于研究、生产、质量控制和电泳浴过程控制。 4.2 测试方法中描述了测定水电导率的其他相关方法 D1125美元 。

1.1 This test method covers the determination of the electrical conductivity of electrocoat baths or ultrafiltrate samples using commercially available equipment. 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 conductivity of electrocoat baths results from the presence of ionic species in the bath, which come from the vehicle and from the presence of impurities present as ionizable acids, bases, salts, or combinations of these. The presence of excessive amounts of ionic impurities is detrimental to the application and performance properties of electrocoating paints. The test is suitable for use in research, production, quality control and electrocoat bath process control. 4.2 Other related methods for determining the electrical conductivity of water are described in Test Methods D1125 .
