IEC 63360 ED1

Fluids for electrotechnical application - Specification of gases alternative to SF₆ to be used in electrical power equipment

Scope

IEC 63360 ED1:2024 (EN) specifies the quality of gases alternative to SF6 (subsequently referred to as gases) for use in electrical power equipment.
Detection techniques, applicable to the analysis of gases prior to their introduction into the electrical power equipment, are also described in this document.
Information about gases by-products and the procedure for evaluating the potential effects of gases and its by-products on human health are covered by IEC 63359[1][1] and IEC 62271-4.
It is the responsibility of the gas manufacturer to make available sufficient information for safe handling of gases and a risk assessment.
For gases not mentioned in this document, the electrical power equipment manufacturer and/or gas manufacturer provides the information indicated in this document. It is the intention of this document to include such gases in a next edition or in amendments to this edition. This document provides information to prepare risk assessment associated with the use of gases. It is the responsibility of the user of this document to establish appropriate health and safety practices and determine the applicability of regulatory limitations prior to use.
NOTE 1 Throughout this document, the term "pressure" stands for "absolute pressure".
NOTE 2 If not otherwise specified in this document, concentration values (e.g. %, ppmv, µl/l) of gas components or contaminants are given in volume fraction at 20 °C and 100 kPa. More information on temperature and pressure dependance of mole fraction and volume fraction is given in Annex C.
NOTE 3 If gases for electrical power equipment are regulated, their designation and regulation origin can be found in the IEC 62474 database [2] (available at https://std.iec.ch/iec62474 [viewed 2024-02-19]).
NOTE 4 Handling of gases is covered by IEC 62271-4:2022.
NOTE 5 Additional information is needed from gas manufacturer and/or electrical power equipment manufacturer to perform a full risk assessment.
