1.1 本试验方法包括从溶剂可还原涂料中分离颜料，并根据总颜料和分离的载体的非挥发性测定结果计算颜料百分比。 注1: 该试验方法已被证明适用于大多数溶剂可还原涂料，但含有严重渗出颜料或炭黑等颜料的涂料除外，这些颜料很难或不可能离心。 1.2 以国际单位制表示的值应视为标准值。本标准不包括其他测量单位。 1.3 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。 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《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====== 3.1 本试验方法描述了从溶剂可还原涂料中快速分离颜料的方法。 3.2 涂料生产商和消费者使用该测试方法进行产品验收和过程控制。

1.1 This test method covers the separation of pigment from solvent-reducible paints and the calculation of the percent pigment from the results of nonvolatile determinations on the total paint and the separated vehicle. Note 1: This test method has been proven to be applicable to most solvent-reducible paints, the exception being those paints containing severely bleeding pigments or pigments such as carbon black that are very difficult or impossible to centrifuge. 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 ====== 3.1 This test method describes a rapid method for separating pigment from solvent-reducible paints. 3.2 This test method is used by paint producers and consumers for product acceptance and process control.
