Many dusts that are generated, processed, handled and stored are combustible. To reduce the likelihood of ignition of the external explosive atmosphere, all such electrical apparatus should be adequately protected. Electrical apparatus for use in the presence of combustible dust Part 0: Search all products by. BS EN specifies general requirements for the design, construction, testing and marking of electrical apparatus protected by any recognized safeguard technique for use in areas where combustible dust may be present in quantities that could lead to uec fire or explosion hazard.
IEC Explosive atmospheres Part In electrical apparatus, potential ignition sources include electrical arcs and sparks, hot surfaces and frictional sparks. The temperature at which a type of dust ignites is a function of the properties of the dust, whether the dust is in a cloud or layer, the thickness of the layer and the geometry of the heat source.
The method used is not to adversely affect the integrity of the enclosure. All International European Italian. Combustible dust can be ignited by electrical apparatus in several ways: Construction, test and marking of type of protection “n” electrical apparatus. This standard does not take account of any ied due to an emission of flammable or toxic gas from the dust.

Several techniques are available for the explosion protection of electrical apparatus in hazardous areas. The contents of the corrigendum of November have been included in this copy. Elektrische Betriebsmittel zur Verwendung in Bereichen mit brennbarem Staub. Please download Chrome or Firefox or view our browser tips.
When ignited they can burn rapidly and with considerable explosive force if mixed with air in the appropriate proportions. Protection by enclosures ‘tD’. By mechanical sparking or frictional sparking or heating associated with the apparatus.
Equipment protection by flameproof enclosures “d”. Customers who bought this product also bought BS EN You may experience issues viewing this site in Internet Explorer 9, 10 or By radiated energy e.
This standard does not apply to dusts of explosives that do not require atmospheric oxygen for combustion, or to pyrophoric substances. Electrical apparatus for use in the presence of combustible dust Part It 6141-0 the relevant text which interfaces the standard directly to the ATEX Directive without technical change other than in marking and amplification of the instructions in order to allow harmonization of the standard.
Equipment protection by increased safety “e”. This standard does not specify requirements for safety, other than those directly related to the explosion risk.
Where the apparatus has to meet other environmental conditions, for example, protection against ingress of water and resistance to corrosion, additional methods of protection may be necessary.
