JRA (Standard of the Japan Refrigeration and Air Conditioning Industry Association)
JRA standards are established and published with a view to realizing quality improvement, rational production, simple and fair trade, as well as rational use or consumption, of products and components relating to refrigeration and air conditioning, through proper and rational standardization of those products and components.


JRA 2007E-1990 Charging Valves for Automotive Air Conditioners(R12) ¥1,100
    This standard specifies charging valves for automotive air conditioners which use R12 refrigerant and of which design pressure is 3 MPa.  
JRA 2009E-1991 Charging Valves for Automotive Air Conditioners(HFC-134a) ¥1,100
    This standard specifies charging valves for automotive air conditioners which use R134a refrigerant and of which design pressure is 3.5 MPa.  
JRA 2010E-1994 Refrigerant Service Cans for Automotive Air Conditioners ¥1,100
    This standard specifies simple, non-refillable refrigerant service cans which are mainly used in the market to charge automotive air conditioners with R134a or R12.  
JRA 4068T:2016R Requirements of refrigerant leak detector and alarm for air conditioning and refrigeration equipment ¥2,460
    This standard has been established for the standardization of the specifications for refrigerant leak detectors and alarms that are compliant with Refrigeration Safety Regulation under High Pressure Gas Safety Act and detectors and alarms that are non-compliant with the said regulations for greater ease in use for air conditioning and refrigeration equipment manufacturers, installation service operators and users and hence the wider promotion of the standards in the marketplace without any confusion.
 
JRA-GL (Guideline of the Japan Refrigeration and Air Conditioning Industry Association)
JRA guidelines are established and published to give technical guidance on products, components, practices and services relating to refrigeration and air conditioning.


JRA GL02E-1994 Guideline of Water Quality for Refrigeration and Air Conditioning Equipment ¥6,000
    This guideline provides water quality standards for cooling water, chilled water and mid-range temperature water supplied to refrigeration and air conditioning equipment, as well as the water quality control methods, with the purpose of maintaining, or preventing deterioration of, performance, efficiency and service life of those equipment.
