The International Institute of Ammonia Refrigeration (IIAR) is a professional society and trade association dedicated to the use of natural refrigerants, the most prevalent of which is ammonia. IIAR members embrace the safe use of ammonia because of its energy efficiency, ease of use, and wide availability. Soon celebrating 50 years as a professional society, IIAR has developed numerous standards and guidelines that are recognized by government agencies, model codes, and associated organizations in the United States and internationally. Our member library contains hundreds of technical papers on a wide array of topics regarding the use of ammonia. This session will provide a brief overview of the standards and guidelines that IIAR has developed. These materials and the development process could serve as a template for similar efforts in the ammonia energy industry.
