1 Scope This document provides the quality of gases alternative to SF 6 (subsequently referred to as gases) for their re-use in electrical power equipment after recovery and if applicable reclaiming (e.g., during maintenance, repair, overhaul or at the end-of-life). The re-use criteria consider technical and environmental concerns. This document covers the same gases as listed in IEC 63360 . For gases not mentioned in this document, the electrical power equipment manufacturer and/or the gas manufacturer provide 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. Procedures for recovering and reclaiming of used gases are described in IEC 62271‑4:2022 . NOTE 1     Reclaiming procedures of gases can be done by either reclaiming the complete gas or by separating the most valuable components from the gas. Gas analysis techniques for checking the quality of the gas are described in this document. It is the responsibility of the gas manufacturer and/or the electrical power equipment manufacturer to provide sufficient information for safe handling of gases and to provide a risk assessment. It is the responsibility of the user of the electrical power equipment to establish appr...
