1.1 本实施规程描述了评估稀释用于水性施用的农药罐混合物的物理相容性和稳定性的方法。该实践也可适用于与液体肥料一起使用以代替水稀释剂。 1.2 罐混合相容性会受到许多变量的影响。应注意重复测试条件。该实践涉及标准变量，如时间、温度、水硬度、搅拌方法和搅拌程度。 1.3 相容性是复杂的，并且可能受到其他变量的影响，例如添加顺序、稀释水的pH、泵送剪切等。在本实践的参数下，结果将确定农药混合物在实验室中是否相容。相容性或不相容性应在田间喷雾条件下确认。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 阅读并遵循特定制剂的所有处理说明，并根据药物非临床研究质量管理规范进行检测。 1.6 以SI单位表示的值将被视为标准值。本标准不包括其他计量单位。 1.7 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。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法规限制的适用性。 1.8 本国际标准是根据国际公认的标准化原则制定的世界贸易组织技术性贸易壁垒委员会。 ======意义和用途====== 4.1 这种做法是为农药的研究人员、施用者和最终用户设计的，其中一种或多种成分被混合到水性喷雾系统中。该实践可用于确定农药和/或肥料的水性喷雾混合物的物理相容性。 4.2 该实践不是为了确定非水基喷雾混合物的物理相容性而设计的。 4.3 结果或测试应用于确定混合物成分在动态应用中的相容性。不鼓励将静态结果插值到本测试结果的预期中。

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.
