1.1 本试验方法用于测定干农药制剂的悬浮百分比。 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、健康和环境实践，并确定监管限制的适用性。 有关具体的预防说明，请参阅第节 7. . 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《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====== 4.1 本试验方法专为干燥配方设计，但不限于这些材料。 4.2 本试验方法的任一选项（参见第节 8. )可用于确定悬浮性百分比。 4.3 本试验方法可能不适用于所有干燥配方，例如那些含有液体或可溶性技术/农药或成分的配方，这些成分在分离时会上升到顶部。 4.4 本试验方法可能不适用于含有在试验条件下分解成分的配方。 4.5 如果发生絮凝，本试验方法可能不会给出可重复的结果。 4.6 本试验方法应一式两份。 4.7 含有水溶性或挥发性成分的产品可能会导致错误。

1.1 This test method is used to determine the percent suspensibility of dry pesticide formulations. 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. For specific precautionary statements see Section 7 . 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 This test method is designed specifically for dry formulations, but need not be restricted to these materials. 4.2 Either option of this test method (see Section 8 ) may be used to determine the percent suspensibility. 4.3 This test method may not be applicable to all dry formulations such as those containing liquid or soluble technical/pesticides or ingredients that rise to the top upon separation. 4.4 This test method may not be applicable to formulations containing ingredients that decompose under the test conditions. 4.5 This test method may not give reproducible results if flocculation occurs. 4.6 This test method should be run in duplicate. 4.7 Products containing water soluble or volatile components may result in errors.
