Non-Metallic Automotive Air-Conditioning Refrigerant Line Assembly Requirements
The Scope of the standard will cover non-metallic line assembly requirements intended for containing and circulating lubricant, liquid and gaseous R-134a and /or R-1234yf refrigerant in automotive air-conditioning systems. The standard will also provide the necessary values used in SAE J2727 Mobile Air Conditioning System Refrigerant Emission charts for R-134a and R-1234yf.
Rationale: A new standard is required to identify the requirements and refrigerant permeation values for SAE J2727. The use of non-metallic tube material is unique and is not addressed in SAE J2064 Coupled Refrigerant Automotive Air-Conditioning Hose Assembly Requirements.
