UNE-EN IEC 63360:2026

This document specifies the quality of gases alternative to SF6 for use in electrical power equipment.

Detection techniques, covering in-situ portable instrumentation, applicable to the analysis of gases alternative to SF6 prior to the introduction of these gases into the electrical power

equipment, are also described in this document.

Information about gases alternative to SF6 by-products and the procedure for evaluating the potential effects of gases alternative to SF6 and its by-products on human health are covered

by IEC 63359 and IEC 62271-4, their handling and disposal being carried out according to international, national and local regulations with regard to the impact on the environment and

the safety of operators.

It is the responsibility of the gas manufacturer to provide sufficient information for safe handling of gases alternative to SF6 and a risk assessment, in accordance with international, national,

and local regulations.

For gases alternative to SF6 not mentioned in this document the electrical power equipment manufacturer and/or gas manufacturer shall provide the information indicated in this document.

It is the intention of this document to include such gases alternative to SF6 in a next edition or in amendments to this edition. This document provides information to prepare risk assessment

associated with the use of gases alternative to SF6. 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, ¼l/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 alternative to SF6 for electrical power equipment are regulated, their designation and regulation origin might be found in the IEC 62474 database [1] (available at https://std.iec.ch/iec62474).

NOTE 4 Handling of gases alternative to SF6 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.
