PD IEC/TS 60079-46:2017

What is PD IEC/TS 60079-46‒ Equipment assemblies about? 

PD IEC/TS 60079-46 is a part of an international multi-series standard that covers safety requirements for explosive atmospheres. 

PD IEC/TS 60079-46 is a technical specification, that specifies requirements for the design, construction, assembly, testing, inspection, marking, documenting, and assessment of equipment assemblies for the use in explosive atmospheres under the responsibility of the manufacturer of the equipment assembly. 

PD IEC/TS 60079-46 applies 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. 

PD IEC/TS 60079-46 includes an assessment of the additional requirements for assemblies for hazardous areas and does not include requirements for non-hazardous areas. 

Note 1: PD IEC/TS 60079-46 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 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 

Who is PD IEC/TS 60079-46‒ Equipment assemblies for? 

PD IEC/TS 60079-46 on equipment assemblies, is useful for: 

• Designers of electrical equipment in an explosive atmosphere 
• Manufacturers of safety equipment in an explosive atmosphere 
• Underground mine authorities 
• Oil and petroleum gas industries 
• Industries with the explosive work atmosphere  

Why should you use PD IEC/TS 60079-46‒ Equipment assemblies? 

The safety of the personnel working in an explosive atmosphere, equipment, protective systems, or components can be achieved by eliminating hazards and/or limiting the risk. 

PD IEC/TS 60079-46 provides you with requirements for the design, construction, assembly, testing, inspection, marking, documenting, and assessment of equipment assemblies, so that the items of Ex Equipment and the interconnection of the items of equipment, form an assembly.   

PD IEC/TS 60079-46 is useful for you to verify the assemblies to assist in ensuring you that all the products are in compliance with the requirements of the IEC 60079 series at the time of initial installation at the end-user site. After the initial installation, the assembly is considered as part of the site installation in accordance with other parts of the IEC 60079 series.
