Anotation

IEC TS 60079-46:2017 specifies requirements for the design, construction, assembly, testing, inspection, marking, documenting and assessment of equipment assemblies for use in explosive atmospheres under the responsibility of the manufacturer of the equipment assembly. The requirements of this document apply to individual items according to the IEC 60079 series or ISO 80079 series that comprise the assembly and that have individual certificates. These individual items are then integrated as part of the equipment assembly. Also included are requirements to address aspects for the assembly which may be beyond the certificates of the individual items forming the assembly. The scope of this document includes assessment of the additional requirements for assemblies for hazardous areas and does not include requirements for non-hazardous areas. It is assumed that compliance with other electrical or mechanical requirements that are applicable for non-hazardous areas will be verified by either the same or different party in addition to the requirements of this document. This document does not apply to: - equipment which is covered, in its entirety, by one or more IEC 60079 and ISO 80079 equipment types of protection; - pressurized rooms, “p”, in accordance with IEC 60079-13, artificial ventilation for the protection of analyzer(s) houses in accordance with IEC TR 60079-16, and other standards addressing specific Ex assemblies; - installation at the end-user site under the scope of IEC 60079-14; - classification of the hazardous area; - equipment assemblies for mines susceptible to firedamp (Group I applications); - inherently explosive situations and dust from explosives or pyrophoric substances (for example explosives manufacturing and processing); - rooms used for medical purposes; - electrical installations in areas where the hazard is due to flammable mist. The specification is only intended to provide validation for the initial supply of an assembly. Keywords: equipment assemblies for use in explosive atmospheres IEC TS 60079-46:2017 specifie les exigences relatives a la conception, a la construction, a l’assemblage, aux essais, aux inspections, au marquage, a la documentation et a l’evaluation des assemblages d’appareils destines a etre utilises en atmospheres explosives, sous la responsabilite du fabricant de l’assemblage d’appareils. Les exigences du present document s’appliquent aux elements individuels conformement aux series IEC 60079 ou ISO 80079 qui composent l’assemblage et qui disposent de certificats individuels. Ces elements individuels sont ensuite integres en tant que partie de l’assemblage d’appareils. Sont egalement incluses des exigences concernant des aspects de l’assemblage qui peuvent aller au-dela des certificats des elements individuels formant l’assemblage. Le domaine d’application du present document inclut l’evaluation des exigences supplementaires applicables aux assemblages pour des emplacements dangereux et ninclut pas d’exigences pour les emplacements non dangereux. Il est suppose que la conformite a d’autres exigences electriques ou mecaniques applicables pour des emplacements non dangereux sera verifiee par la meme partie ou par une autre partie, en complement des exigences du present document. Le present document ne s’applique pas: - aux appareils qui sont couverts, dans leur integralite, par un ou plusieurs modes de protection d’appareils conformes a l’IEC 60079 et a l’ISO 80079; - aux salles a surpression interne, «p», conformes a l’IEC 60079-13, a la ventilation artificielle pour la protection des batiments pour analyseur(s) conforme a l’IEC TR 60079 16, et a d’autres normes traitant d’assemblages Ex specifiques; - a l’installation sur le site de l’utilisateur final, qui releve du domaine d’application de l’IEC 60079-14; - au classement de l’emplacement dangereux; - aux assemblages d’appareils pour les mines grisouteuses (applications du Groupe I); - aux situations intrinsequement explosives et aux poussieres issues de substances explosives ou pyrophoriques (la fabrication et le traitement d’explosifs, par exemple); - aux salles utilisees a des fins medicales; - aux installations electriques situees dans des emplacements ou le danger provient dun brouillard inflammable. La specification est destinee uniquement a assurer la validation de la fourniture initiale dun assemblage.
