1.1 本试验方法描述了测定农药乳油用水稀释时乳化自发性和乳化稳定性特征的一般程序。这种方法是对成功或失败的非定量报告。 1.2 使用农药制剂时，必须采取适当的安全和卫生预防措施，以防止皮肤或眼睛接触、蒸汽吸入和环境污染。阅读并遵循特定配方的所有处理说明，并按照良好实验室规范进行测试。 1.3 以国际单位制表示的值应被视为标准值。本标准不包括其他计量单位。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、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====== 5.1 本试验方法为评估农药乳油的乳化特性提供了指南。它定义了乳化颗粒在水中的稳定性。虽然不是绝对的，但该测试方法是衡量农业应用设备中预期乳液稳定性的一种方法。

1.1 This test method describes a general procedure for the determination of emulsification spontaneity and the emulsion stability characteristics of pesticide emulsifiable concentrates when diluted with water. This method is a nonquantitative report of success or failure. 1.2 Proper safety and hygiene precautions must be taken when working with pesticide formulations to prevent skin or eye contact, vapor inhalation, and environmental contamination. Read and follow all handling instructions for the specific formulation and conduct the test in accordance with good laboratory practice. 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 ====== 5.1 This test method provides a guide for evaluating emulsification characteristics of pesticide emulsifiable concentrates. It defines the stability of emulsified particles in water. Although not absolute, the test method is a measure of expected emulsion stability in agricultural application equipment.
