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 2009T:1993 Charging valves for automotive air conditioners(HFC-134a) ¥740
    This standard specifies charging valves for automotive air conditioners using HFC-134a as refrigerant and of which design pressure is 3.5 MPa  
JRA 2010T:2012 Refrigerant service cans for automotive air conditioners ¥860
    This standard specifies simplified refrigerant service cans which are used mainly to fill refrigerants to automotive air conditioners in which HFC-134a, CFC-12 and R-1234yf are used as refrigerants.  
JRA 2018T:2012 Refrigerant service tools for automotive air conditioners(R-1234yf) ¥740
    This standard specifies refrigerant service tools for automotive air conditioners using R-1234yf as refrigerant, namely, gas-filling tool and service can valves used in refrigerant filling, etc.  
JRA 4068T:2016R Requirements of refrigerant leak detector and alarm for air conditioning and refrigeration equipment ¥2,460
    This standard specifies refrigerant service tools for automotive air conditioners using R-1234yf as refrigerant, namely, gas-filling tool and service can valves used in refrigerant filling, etc.
 
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 GL-02E: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.  
GL-20T:2016
(DRAFT)
Appropriate measures to prevent combustion against refrigerant gas leakage from the refrigerant charged equipment using particular inert gas  
    This guideline establishes the method for safely managing and preventing combustion in case of refrigerant leakage from refrigerant charged equipment that uses particular inert gas regulated in Refrigeration Safety Regulation under High Pressure Gas Safety Act but owned by high-pressure gas producers operating in the scale of 5 to less than 20 legal tons of refrigeration (other producing) that does not require reporting to the regulatory authorities.
