SAE J3062 Automotive Refrigerant Air Conditioning Hose Requirements

EUROLAB laboratory provides testing and compliance services within the scope of SAE J3062 standard. The SAE J3062 standard, developed by the Society of Automobile Engineers (SAE), covers hoses intended to contain lubricant, liquid and gaseous R-134a, R-152a or R-1234yf refrigerant and provide circulation in automotive air conditioning systems.

The hose shall be designed to minimize refrigerant penetration, contamination of the system and be functional in the temperature range of -30 to 125 °C. The specific construction details will be agreed between the user and the supplier.

Hose requirements for combined automotive refrigerant air conditioning assemblies are included in SAE J2064. SAE J3062 breaks down the requirements for the hose used in these assemblies into its own standard. SAE J2064 also provides the required refrigerant permeability values ​​used in SAE J2727.

Mobile air conditioning system refrigerant emission rates are determined and important in SAE J2727 emission charts. Certified connection of MAC hose assemblies is required to meet certain regulatory requirements.

Therefore, the scope of SAE J2064 has been changed to specify assembly requirements for factory and field-connected hose assemblies. A hose that meets the requirements of SAE J3062 may not meet the requirements of SAE J2064. Cast hose manufactured prior to the publication of this standard may be labeled "SAE J2064" and may not meet the requirements of SAE J3062.

Our organization provides automotive refrigerant air conditioning hose requirements services within the scope of SAE J3062 standard, within the framework of national and international standards, with its trained and expert staff and advanced technological equipment, among numerous test, measurement, analysis and evaluation studies.
