ANSI/ASHRAE Standard 34-2022 (Supersedes ANSI/ASHRAE Standard 34-2019) Includes ANSI/ASHRAE addenda listed in Appendix J 1. PURPOSE 1.1 This standard is intended to establish a simple means of referring to common refrigerants instead of using the chemical name, formula, or trade name. It establishes a uniform system for assigning reference numbers, safety classifications, and refrigerant concentration limits to refrigerants. The standard also identifies requirements to apply for designations and safety classifications for refrigerants and to determine refrigerant concentration limits 2. SCOPE 2.1 This standard provides an unambiguous system for numbering refrigerants and assigning composition-designating prefixes for refrigerants. Safety classifications based on toxicity and flammability data are included along with refrigerant concentration limits for the refrigerants. This standard does not imply endorsement or concurrence that individual refrigerant blends are suitable for any particular application Committee Chair Dr Sarah Kim Webmaster Mr Ivan Rydkin Upcoming Society Conferences ASHRAE 2024 Annual Conference June 22-26, 2024 Indianapolis, IN Information for Applicants SSPC 34 Applications for consideration at the 2024 Indianapolis Annual Meeting are due by May 17,2024 to the Senior Manager of Standards .
