Standard Test Method for Pigment Content of Water-Emulsion Paints by Low-Temperature Ashing 低温灰化法测定水乳液涂料中颜料含量的标准试验方法
发布日期: 2022-07-01
1.1 本试验方法涵盖了水基涂料的颜料含量测定程序。它仅适用于温度低于500℃时不会分解或减重的颜料 °C。此类颜料包括大多数金属氧化物、硅酸盐和大多数无水无机盐。 1.2 许多水性涂料含有颜料和有机着色剂,这些颜料和着色剂在这个温度下会失去水分或分解。应仔细检查残余灰烬的颜色或纹理变化,以确定是否存在可能表明颜料变化的情况,从而导致错误的结果。 因此,当将本试验方法应用于含有未知颜料成分的样品时,应小心。 1.3 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。 1.4 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。 1.5 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====== 3.1 本试验方法由油漆生产商和消费者用于产品过程控制和产品验收。
1.1 This test method covers a procedure for the pigment content determination of water-based paints. It is applicable only to pigments that do not decompose or lose weight at temperatures below 500 °C. Such pigments include most metal oxides, silicates, and a majority of anhydrous inorganic salts. 1.2 Many water-based paints contain pigments and organic colorants that lose water of hydration or decompose at this temperature. The residual ash should be carefully inspected for changes in color or texture that could indicate a pigment alteration and hence lead to erroneous results. Caution should therefore be exercised when applying this test method to samples containing unknown pigment compositions. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. 1.5 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 is used by paint producers and consumers for product process control and for product acceptance.
