ICS 71.100.45                          MED 03

(Superseding IS/ISO 817 : 2005)

Reaffirmed 2021

NATIONAL FOREWORD

This Indian Standard which is identical with ISO 817 : 2014 ‘Refrigerants - Designation and safety classifications’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Refrigeration and Air Conditioning Sectional Committee and approval of the Mechanical Engineering Division Council.

This standard was earlier published as IS/ISO 817 : 2005 ‘Refrigerants - Designation system’. The committee has now decided to adopt this standard under dual numbering system by superseding IS/ISO 817 : 2005. After the publication of this standard IS/ISO 817 : 2005 shall be treated as withdrawn.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
