1.1 本试验方法包括在剪切速率为12时测定涂料、清漆和相关产品的粘度 000秒 −1 。 1.2 快速干燥的色漆和清漆可能无法用该试验方法得出可重复的结果。在高温下进行的测量也可能由于挥发物的损失和干燥而导致精度差。 1.3 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。 1.4 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。 1.5 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 通过该试验方法获得的粘度值提供了材料在高剪切条件下的流动特性信息，类似于在涂刷过程中遇到的情况（见试验方法 D4958 )、喷涂、静电盘或辊涂。 4.2 该试验方法适用于所有油漆和清漆，无论它们是否具有牛顿性质。然而，由于高剪切粘度计的固定部件和旋转部件之间的间隙很窄，该试验方法对于通过试验方法测定的具有更精细颜料分散体的涂料来说更具可重复性 D1210 。

1.1 This test method covers the determination of the viscosity of paints, varnishes, and related products at a rate of shear of 12 000 s −1 . 1.2 Paints and varnishes that dry very rapidly may not give reproducible results with this test method. Measurements made at elevated temperatures may also give poor precision due to loss of volatiles and to drying. 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 ====== 4.1 The viscosity value obtained by this test method gives information about the flow properties of the material under high-shear conditions similar to those encountered during application: brushing (see Test Method D4958 ), spraying, electrostatic disk, or roll coating. 4.2 This test method is suitable for all paints and varnishes whether they are Newtonian in behavior or not. However, due to the narrow gap between the stationary and rotary parts of high-shear viscometers, this test method is more reproducible for paints having finer pigment dispersions as determined by Test Method D1210 .
