1.1 本规程描述了用于评估稀释用于水应用的农药罐混合物的物理兼容性和稳定性的方法。这种做法也可适用于与液体肥料一起使用，以代替水稀释剂。 1.2 储罐混合兼容性可能受到许多变量的影响。应注意复制试验条件。本规程涉及时间、温度、水硬度、搅拌方法和搅拌程度等标准变量。 1.3 相容性很复杂，可能会受到其他变量的影响，如添加顺序、稀释水的pH值、泵切等。根据本规程的参数，结果将确定农药混合物在实验室中是否相容。 应在现场喷涂条件下确认兼容性或不兼容性。 1.4 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。 1.5 阅读并遵循特定配方的所有操作说明，并根据良好实验室惯例进行测试。 1.6 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。 1.7 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。 1.8 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 本规程适用于将一种或多种成分混合到水喷雾系统中的农药研究人员、施用者和最终用户。本规程有助于确定农药和/或肥料的水喷雾混合物的物理相容性。 4.2 本规程的目的不是确定非- 水基喷雾混合物。 4.3 测试结果应用于确定混合物成分在动态应用中的兼容性。不鼓励将静态结果插入本测试结果的预期值。

1.1 This practice describes the method for the evaluation of the physical compatibility and stability of pesticide tank mixtures diluted for aqueous application. This practice may also be adapted to use with liquid fertilizers in replacement of the water diluent. 1.2 Tank mix compatibility can be affected by many variables. Care should be taken to duplicate test conditions. This practice addresses the standard variables such as time, temperature, water hardness, method of agitation, and degree of agitation. 1.3 Compatibility is complex and can be affected by other variables such as order of addition, pH of the dilution water, pumping shear, etc. Under the parameters of this practice, the results will define whether the pesticide mixture is or is not compatible in the laboratory. Compatibility or incompatibility should be confirmed under field spray conditions. 1.4 Proper safety and hygiene precautions must be taken when working with pesticide formulations to prevent skin or eye contact, vapor inhalation, and environmental contamination. 1.5 Read and follow all handling instructions for the specific formulation and conduct the test in accordance with good laboratory practice. 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 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. 1.8 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 practice is designed for researchers, applicators, and end users of pesticides where one or more ingredients are being mixed into an aqueous spray system. The practice is useful in determining physical compatibility of aqueous spray mixtures of pesticides and/or fertilizers. 4.2 The practice is not designed to determine physical compatibility of non-aqueous based spray mixtures. 4.3 The results or the testing should be used to determine the compatibility of the mixture ingredients in dynamic applications. Interpolation of static results to the expectations of the results of this test is not encouraged.
