1.1 本试验方法用于测定干农药制剂的分散性百分比。 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。 4.2 本试验方法可能不适用于所有干燥配方，例如含有水溶性或液体技术/农药或分离时上升到顶部的成分的配方。 4.3 本试验方法可能不适用于在干燥温度以下分解的技术。 4.4 本试验方法应一式两份。 4.5 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 dispersibility 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. 4.2 This test method may not be applicable to all dry formulations such as those containing water soluble or liquid technicals/pesticides or ingredients that rise to the top upon separation. 4.3 This test method may not be applicable to those technicals that decompose below the drying temperature. 4.4 This test method should be run in duplicate. 4.5 Products containing water soluble or volatile components may result in errors.
