制冷剂汽车空调软管

[中文适用范围]： “SAE J2064 的范围涵盖用于在汽车空调系统中容纳和循环润滑剂@液态和气态 R134a 和/或 R-1234yf 制冷剂的耦合软管组件。历史上，对耦合汽车制冷剂空调组件中使用的软管的要求是包含在 SAE J2064 中。SAE J2064 已更改，以建立工厂和现场耦合软管组件的要求。SAE J3062 已发布，将这些组件中使用的软管的要求定义为自己的标准。SAE J2064 还提供了使用的必要值在 SAE J2727 移动空调系统 R-134a 和 R-1234yf 制冷剂排放表中。为了满足某些法规要求，需要经过认证的 MAC 软管组件接头。满足 SAE J3062 要求并在 J2911 中认证的软管必须是用作耦合组件的一部分。满足 SAE J3062 要求的软管并不能确保该组件满足 SAE J2064 的要求。软管组件制造商有责任确认组件符合本规范指定的验收标准。软管组件的设计应尽量减少制冷剂的渗透@系统的污染@，并在-30至125℃的温度范围内正常工作。具体施工细节由用户和供应商协商确定。在该标准发布之前生产的散装软管可能贴有“SAE J2064”标签，并且可能不符合 SAE J3062 的要求。 [外文原描述]： The scope of SAE J2064 covers coupled hose assemblies intended for containing and circulating lubricant, liquid, and gaseous R-134a, R-152a, and/or R-1234yf refrigerant in automotive air-conditioning systems. Historically, requirements for the hose used in coupled automotive refrigerant air conditioning assemblies was included in SAE J2064. SAE J2064 has been changed to establish the requirements for factory and field coupled hose assemblies. SAE J3062 has been issued to define requirements for the hose used in these assemblies into its own standard. SAE J2064 also provides the necessary values used in SAE J2727. The certified coupling of MAC hose assemblies is required in meeting certain regulatory requirements.A hose which has met the requirements of SAE J3062 and certified in SAE J2911 shall be used as part of the coupled assembly. A hose which meets the requirements of SAE J3062 does not ensure the assembly will meet the requirements of SAE J2064. It is the hose assembly manufacturer’s responsibility to confirm that the assemblies meet the specified acceptance criteria for this specification. The hose assembly shall be designed to minimize permeation of the refrigerant, contamination of the system, and to be functional over a temperature range of -30 to 125 °C. Specific construction details are to be agreed upon between user and supplier.Bulk hose produced prior to the release of this standard in 2015 could be labeled “SAE J2064” and may not meet the requirements of SAE J3062.Cross Reference: ASTMD380,J2727_202011,J2911_201612,J3062_202101,J639_202011
