Guidelines for the checking and treatment of sulphur hexafluoride (SF6) taken from electrical equipment and specification for its re-use

Concerns the re-use of sulfur hexafluoride (SF6) after removal from electrical equipment (for maintenance, or at the end of life). This standard recommends procedures for reclaiming used SF6 and for restoring its quality to an acceptable level, which would allow the filling of new or existing electrical equipment. This standard provides guidance to operational and maintenance personnel for the testing and safe handling of used SF6 . The main changes with respect to the previous edition are listed below: - updating of standard as it relates to environmental issues, storage and analytical methods; - addition of specification for the re-use of gas; - inclusion of a regeneration process for sulfur hexafluoride taken from electrical equipment.

Lignes directrices relatives au contrôle et au traitement de l'hexafluorure de soufre (SF6) prélevé sur le matériel électrique et spécification en vue de sa réutilisation

Concerne l'hexafluorure de soufre (SF6) que l'on retire du matériel électrique (pour la maintenance ou en fin de vie) en vue de sa réutilisation. La présente norme recommande des procédures pour la régénération du SF6 usagé et pour la restauration de sa qualité à un niveau acceptable, afin de permettre le remplissage de nouveaux matériels électriques ou de matériels déjà existants. La présente norme fournit des lignes directrices pour que le personnel d'exploitation ou de maintenance réalise des essais ou traite le SF6 usagé en toute sécurité. Les modifications principales par rapport à l'édition précédente sont indiquées ci-dessous: - mise à jour des questions environnementales, de stockage et des méthodes analytiques; - addition de spécification pour la réutilisation du gaz; - incorporation du processus de régénération de l'hexafluorure de soufre prélevé sur le matériel électrique.

GUIDELINES FOR THE CHECKING AND TREATMENT OF SULFUR HEXAFLUORIDE (SF6) TAKEN FROM ELECTRICAL EQUIPMENT AND SPECIFICATION FOR ITS RE-USE
FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearl
