The SAE J2064 standard, developed by the Society of Automotive Engineers (SAE), describes the requirements for hose and hose assemblies intended to deliver liquid and gaseous R134a refrigerant in automotive air conditioning systems. The hose is designed to minimize refrigerant permeability, contamination of the system and be functional in the temperature range of minus 30 to plus 125 degrees. Custom construction details are agreed between the user and the supplier.
A hose marked J2064-R134a, J2064-R-1234yf, or J2064-R134a/R-1234yf indicates that the hose has been connected, tested, and meets the requirements of the SAE J2064 standard for marked refrigerants. A hose marked J2064 with no reference to the refrigerant indicates that it has been connected, tested and meets the requirements of R134a only. It is the responsibility of the manufacturer of the hose assembly to prove that the assemblies meet the acceptance criteria specified for this specification.
The SAE J2064 standard covers connected hose assemblies intended to contain lubricant, liquid and gaseous R134a or R-1234yf refrigerant and provide circulation in automotive air conditioning systems. This standard also provides the required values for R-134a and R-1234yf used in the SAE J2727 standard (this standard includes mobile air conditioning system refrigerant emission tables).
Thermal management refers to heating and cooling the vehicle cabin, as well as maintaining optimum engine temperature under all operating conditions. A modern thermal management system therefore consists of engine cooling and air conditioning components. Air conditioning systems naturally require hoses and hose assemblies responsible for conveying liquid and gaseous refrigerants.
Mobile air conditioning systems in the automotive industry generally use engine driven compressors with R134a refrigerant. However, R134a fluid will be discontinued in the near future. R-1234yf fluid is a new low global warming refrigerant developed to replace R134a, which has been phased out in European Union countries due to its higher global warming potential.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides R2064a refrigerant automotive air-conditioned hose testing services within the scope of SAE J134 standard, with its trained and expert staff and advanced technological equipment.
