BS EN 60079-13:2017 PDF Download

BS EN 60079-13:2017 is a standard that provides requirements for the design, construction, assessment, verification, and marking of rooms used to protect internal equipment in explosive atmospheres. The standard covers different scenarios, such as rooms located in Zone 1 or Zone 2 explosive atmospheres without an internal source of gas/vapour release and protected by pressurization, rooms located in Zone 2 explosive atmospheres with or without an internal source of gas/vapour release and protected by artificial ventilation, rooms located in non-hazardous areas with an internal source of gas/vapour release and protected by artificial ventilation, and rooms located in explosive atmospheres with an internal source of gas/vapour release and protected by both pressurization and artificial ventilation.

The term "room" in this standard refers to single rooms, multiple rooms, a complete building, or a room within a building. The standard also includes requirements for safety devices and controls to establish and maintain artificial ventilation, purging, and pressurization.

BS EN 60079-13:2017 applies to rooms used in explosive gas atmospheres requiring different equipment protection levels and combustible dust atmospheres. However, it does not specify methods for ensuring air quality for personnel or protection of rooms using inert or flammable gases. These cases may require additional engineering standards, procedures, and practices.

This standard supplements and modifies the general requirements of IEC 60079-0, with the requirements of BS EN 60079-13:2017 taking precedence in case of conflicts. The standard also includes a table that identifies specific clauses or subclauses of IEC 60079-0 that are excluded or modified in BS EN 60079-13:2017. Maintenance recommendations are contained in Annex A until they can be included in IEC 60079-17.
