(Main)Explosive atmospheres - Part 30-1: Electrical resistance trace heating - General and testing requirements
Explosive atmospheres - Part 30-1: Electrical resistance trace heating - General and testing requirements
IEC/IEEE 60079-30-1:2015 specifies general and testing requirements for electrical resistance trace heaters for application in explosive atmospheres with the exclusion of those for EPL Ga and Da. This standard covers trace heaters that comprise either factory or field (work-site) assembled units, and which may be series trace heaters, parallel trace heaters, trace heater pads, or trace heater panels that have been assembled and/or terminated in accordance with the manufacturer's instructions. This standard also includes requirements for termination assemblies and control methods used with trace heating systems. The explosive atmospheres referred to in this standard are those defined in IEC 60079-10-1 and IEC 60079-10-2. Annexes D and E outline the application of this standard for those users applying the Division method of area classification. This standard supplements and modifies the general requirements of IEC 60079-0, except as indicated in Table 1 (refer to Clause 1 - Scope of the document). Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of this standard takes precedence. This first edition of IEC/IEEE 60079-30-1 cancels and replaces the first edition of IEC 60079-30-1 published in 2007 and constitutes a technical revision. This edition includes the following significant changes, apart from the general revision and updating of the first edition of IEC 60079-30-1 and harmonization with IEEE Std.515, with respect to the previous edition:
- the inclusion of a minimum temperature impact test;
- the addition of a mechanical procedure in the thermal stability test;
- the inclusion of a thermal performance test to replace the thermal safety requirements;
- the inclusion of a second procedure utilizing a plate fixture for sheath temperature determination;
- the inclusion of an ultraviolet and condensation test;
- the revision and significant expansion of documentation requirements;
- the addition of Annexes covering requirements for Divisions 1 and 2;
- the addition of a table covering the applicability of requirements from IEC 60079-0;
- the addition of an Annex covering trace heater product design verification methodology (formerly located in IEC 60079-30-2);
- the further harmonization of this edition with several national standards. Please refer to the Foreword of the document for the significance of changes between IEC 60079-30-1, Edition 1.0 (2007) and IEC/IEEE 60079-30-1, Edition 1.0 (2015). Keywords: electric surface heating equipment used in explosive atmospheres, equipment protection levels Gb, Gc, Db, and Dc
Atmosphères explosives - Partie 30-1: Traçage par résistance électrique - Exigences générales et d'essais
IEC/IEEE 60079-30-1:2015 spécifie les exigences générales et d'essai des résistances électriques de traçage pour une application en atmosphères explosives, à l'exclusion de celles pour les EPL Ga et Da. La présente norme s’applique aux résistances de traçage composées d'unités assemblées en usine ou sur site (site d’exploitation) et qui peuvent être des résistances de traçage en série, des résistances de traçage en parallèle, des bandes de traçage ou des panneaux de traçage qui ont été assemblés et/ou équipés de terminaisons conformément aux instructions du constructeur.
La présente norme comprend aussi des exigences concernant les ensembles de terminaisons et les méthodes de contrôle appliquées aux systèmes de traçage. Les atmosphères explosives désignées dans la présente norme sont celles définies dans l'IEC 60079-10-1 et l'IEC 60079-10-2.
Les Annexes D et E présentent l’application de la présente norme pour les utilisateurs qui appliquent la méthode de classement des emplacements par division.
La présente norme complète et modifie les exigences générales de l'IEC 60079-0, sauf pour ce qui est indiqué au Tableau 1. Lorsqu’une exigence de la présente norme est en conflit avec une exigence de l'IEC 60079-0, l’exigence de la présente norme prévaut Cette première édition annule et remplace la première édition de l'IEC 60079-30-1 parue en 2007. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes, hormis la révision générale et la mise à jour de la première édition de l'IEC 60079-30-1 et de l'harmonisation avec la norme IEEE 515, par rapport à l'édition précédente:
• inclusion d'un essai de choc à température minimale;
• addition d'une procédure mécanique dans l'essai de stabilité thermique;
• inclusion d'un essai des performances thermiques pour remplacer les exigences de sécurité thermique;
• inclusion d'une seconde procédure utilisant un appareil à plaque pour déterminer la température de la gaine;
• inclusion d'un essai aux ultraviolets et de condensation;
• révision et extension significative des exigences de documentation;
• addition des Annexes couvrant les exigences des divisions 1 et 2;
• addition d'un tableau couvrant l'applicabilité des exigences de l'IEC 60079-0;
• addition d'une Annexe couvrant la méthode de vérification de la conception des résistances de traçage (auparavant abordée dans l'IEC 60079-30-2);
• harmonisation de la présente édition avec plusieurs normes nationales.
