BS EN 60079-18:2009 Explosive atmospheres. Equipment protection by encapsulation "m"

BS EN 60079-18 gives the specific requirements for the construction, testing and marking of electrical equipment, parts of electrical equipment and Ex components with the type of protection encapsulation “m” intended for use in explosive gas atmospheres or explosive dust atmospheres.

BS EN 60079-18 applies only for encapsulated electrical equipment, encapsulated parts of electrical equipment and encapsulated Ex components where the rated voltage does not exceed 11 kV.

The application of electrical equipment in atmospheres, which may contain explosive gas as well as combustible dust simultaneously may require additional protective measures.

BS EN 60079-18 does not apply to dusts of explosives, which do not require atmospheric oxygen for combustion, or to pyrophoric substances

BS EN 60079-18 does not take account of any risk due to an emission of flammable or toxic gas from the dust.

This standard supplements and modifies the general requirements of BS EN 60079-0. Where a requirement of this standard conflicts with a requirement of BS EN 60079-0, the requirement of this standard shall take precedence.
