Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

This document was prepared by Technical Committee ISO/TC 86, Refrigeration and air-conditioning, Subcommittee SC 8, Refrigerants and refrigeration lubricants.

This fourth edition cancels and replaces the third edition (ISO 817:2014), which has been technically revised. It also incorporates the Amendments ISO 817:2014/Amd 1:2017 and ISO 817:2014/Amd 2:2021.

The main changes are as follows:

— the scope has been expanded to include data necessary for safe applications of the refrigerants;
— the rules of toxicity safety classification to consider acute and chronic toxicity, have been incorporated into 6.1.2;
— requirements to apply for designations, safety classifications, and refrigerant concentration limits for refrigerants, including blends, and requirements to submit new or revised data for refrigerants listed in ISO 817 tables, previously located in Annex F, have been relocated to https://standards.iso.org/iso/817/ma/en/.

Any feedback or questions on this document should be directed to the user’s national standards body. A complete listing of these bodies can be found at www.iso.org/members.html.
