JRA standards and guidelines are hvac&r industry standards and guidelines developed by JRAIA, the Japan Refrigeration and Air Conditioning Industry
Association, and are shown as JRA and JRA-GL, respectively in the listing.


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-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.
