本SAE标准适用于带皮带驱动压缩机的车辆空调系统的制冷剂回路中售后使用的任何和所有添加剂和化学溶液，以下说明除外。本标准提供了用于确定添加剂和冲洗材料（溶液）与A/C系统材料和部件的稳定性和相容性的测试和验收标准，这些材料和部件可能用于车辆空调系统的维修或操作。 本标准没有提供添加剂、压缩机润滑剂或冲洗液有效性的测试标准；此类测试由添加剂和/或溶液制造商/供应商负责。本标准不包括电动压缩机的添加剂或冲洗材料。在电动压缩机中使用添加剂可能会导致电气短路和压缩机故障。本文件无意确定紫外线检漏染料的要求。此类染料必须满足SAE J2297对预期制冷剂的要求。 移动式空调系统的添加剂不在本标准下进行系统增强或性能测试。本标准仅表明添加剂是否与系统组件中使用的材料化学相容。 冲洗溶剂在使用时完全填充被冲洗的组件/系统，因此在100%浓度下不应损害系统组件。它们不打算作为溶剂或添加剂保留在系统中，但是，因为不可能除去所有的冲洗溶剂，所以保留了不确定的量。残留在系统中的残留物取决于许多因素，包括系统/组件配置、液体无法去除的组件盲点、溶剂的挥发性、用于去除溶剂的程序以及排空能力和程序。不存在鉴定和/或指定在遵循一个或多个程序后可以或将保留在任何给定系统中的残留溶剂的量的方法。本标准不涉及冲洗溶剂程序或其去除残留冲洗剂的有效性。

This SAE standard applies to any and all additives and chemical solutions intended for aftermarket use in the refrigerant circuit of vehicle air-conditioning systems with belt-driven compressors, except as noted below. This standard provides testing and acceptance criteria for determining the stability and compatibility of additives and flushing materials (solutions) with A/C system materials and components, that may be intended for use in servicing or operation of vehicle air conditioning systems. This standard does not provide test criteria for additive, compressor lubricant, or flushing solution effectiveness; such testing is the responsibility of the additive and/or solution manufacturer/supplier. This standard does not cover additives or flushing materials for electrically driven compressors. The use of additives with electrically driven compressors might cause electrical shorting and compressor failure. It is not the intent of this document to identify the requirements for ultraviolet leak detection dyes. Such dyes must meet the requirements of SAE J2297 for the intended refrigerant. Additives for mobile air conditioning systems are not tested under this standard for system enhancement or performance. This standard only indicates if the additive is chemically compatible with materials used in the system components. Flushing solvents, when used, completely fill the component/system being flushed and, hence, should not harm system components at 100% concentration. They are not intended to remain in the system, either as a solvent or as an additive, but, because it is not possible to remove all of the flushing solvent, an indeterminate amount remains. The residual remaining in the system depends on many factors, including system/component configuration, component blind spots where liquid cannot be removed, the volatility of the solvent, the procedure(s) used to remove the solvent, and evacuation capability and procedure. No means exists to identify and/or specify the amount of residual solvent that either can, or will, remain in any given system after the procedure(s) have been followed. This standard does not address the flushing solvent procedure or its effectiveness at removing residual flushing agent.
