The latest version of the factsheet providing up to date information on refrigerant designations and safety classifications can be found HERE.
The factsheet, produced by ASHRAE in cooperation with UN Environment Programme OzonAction is updated every 6 months. The purpose is to provide an update on ASHRAE standards for refrigerants and to introduce the new refrigerants that have been awarded an “R” number (or ASHRAE designation) over the last few years and which have been introduced into the international market.
The factsheet, as well as more information on ASHRAE-UNEP joint activities and tools, is available on the ASHRAE UNEP Portal: https://www.ashrae.org/professional-development/ashrae-unep-portal
