1.1 本试验方法包括通过手动筛分和机器筛分方法测定肥皂和其他洗涤剂的粒径。 1.2 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。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 试剂和材料有材料安全数据表。使用前检查其危险性。 ====意义和用途====== 3.1 本试验方法确保肥皂和洗涤剂的粒径符合与密度和包装等有关的规范。它还提供了一种控制潜在危险极低粒径材料数量的方法。

1.1 This test method covers the determination of the particle size of soaps and other detergents by hand sieving and machine sieving methods. 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 and health practices and determine the applicability of regulatory limitations prior to use. Material Safety Data Sheets are available for reagents and materials. Review them for hazards prior to usage. ====== Significance And Use ====== 3.1 This test method assures that the particle size of soaps and detergents conforms to specifications having to do with density and packaging, among others. It also offers a means of controlling the amount of potentially hazardous very low particle size material.
