R-1234yf and R744 Design Criteria and Certification for OEM Mobile Air Conditioning Evaporator and Service Replacements

2018-10-02
WIP
J2842
The intent of this standard is to establish a framework to assure that all evaporators for R-744, R-1234yf, and R-445A mobile air conditioning (MAC) systems meet appropriate testing and labeling requirements. SAE J639 requires vehicle manufacturers to perform assessments to minimize reasonable risks in production MAC systems. The evaporator (as designed and manufactured) shall be part of that risk assessment and it is the responsibility of the vehicle manufacturer to assure all relevant aspects of the evaporator are included. It is the responsibility of all vehicle or evaporator manufacturers to comply with the standards of this document at a minimum. (Substitution of specific test procedures by vehicle manufactures that correlate well to field return data is acceptable.) As appropriate, this standard can be used as a guide to support risk assessments.

A/C Compressor Oil Separator Effectiveness Test Standard

2018-03-06
WIP
J3112
This SAE Standard establishes the test conditions and reporting method for quantifying refrigerant circuit oil circulation rate (OCR) reduction effectiveness of mobile air conditioning compressors using R-134a and R-1234yf refrigerants that include oil separators and/or other design features for the purpose of reducing the OCR in the refrigerant circuit.

PWM HVAC Blower Controller and BLDC Motor Controller Efficiency Assessment

2017-07-10
CURRENT
J3109_201707
The intention of this standard is to establish a framework to measure the efficiency of PWM HVAC Blower Controllers and Brushless DC Motor Controllers and define a usage based overall efficiency. This result can then be used by vehicle OEMs to demonstrate compliance towards requirements or benchmarks established by regulatory agencies.

Non-Metallic Automotive Air-Conditioning Refrigerant Line Assembly Requirements

2017-05-01
WIP
J3143
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.

Coupled Automotive Refrigerant Air-Conditioning Hose Assemblies

2015-08-28
CURRENT
J2064_201508
The Scope of SAE J2064 covers coupled hose assemblies intended for containing and circulating lubricant, liquid and gaseous R134a 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 Mobile Air Conditioning System Refrigerant Emission charts for R-134a and R-1234yf. 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 J2911 must be used as part of the coupled assembly.

Automotive Refrigerant Air-Conditioning Hose Requirements

CURRENT
J3062_201506
The Scope of SAE J3062 covers hose intended for containing and circulating lubricant, liquid and gaseous R134a and/or R-1234yf refrigerant in automotive air-conditioning systems. The hose 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 the user and supplier. Requirements for the hose used in coupled automotive refrigerant air-conditioning assemblies had been included in SAE J2064. SAE J3062 separates requirements for the hose used in these assemblies into its own standard. SAE J2064 also provides the necessary values used in SAE J2727 Mobile Air-Conditioning System Refrigerant Emission charts for R-134a and R-1234yf. Mobile air-conditioning system refrigerant emissions rates are established in SAE J2727 Emission charts and are important.

R134a Refrigerant Automotive Air-Conditioned Hose

2011-02-04
HISTORICAL
J2064_201102
This SAE Standard covers hose and hose assemblies intended for conducting liquid and gaseous R134a and/or R-1234yf refrigerant in automotive air-conditioning systems. The hose 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. A hose marked “J2064 - R134a”, “J2064 - R-1234yf” or “J2064 - R134a/R-1234yf” signifies that it has been coupled, tested, and has met the requirements of SAE J2064 for the marked refrigerant(s). A hose marked “J2064” without any reference to refrigerant signifies that it has been coupled, tested, and has met the requirements of SAE J2064 for R134a only. It is the hose assembly manufacturer’s responsibility to see that the assemblies meet the specified acceptance criteria for this specification.
