Combustible dust can be ignited by electrical apparatus in several ways: When ignited they can burn rapidly and with considerable explosive force if mixed with air in the appropriate proportions. 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 0: This standard describes the safety features of these types of explosion protection techniques and specifies the installation procedures to be adopted. In particular, it is essential that the severity and duration of an internal or external fault be limited to values that can be sustained by the electrical apparatus without damage. 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.

By arcing or sparking of electrical parts such as switches, contacts, commutators, brushes, or the like. Areas where dust, flyings and fibres in air occur in dangerous quantities are classified as hazardous and are divided into three zones according to the level of risk.
The method used is not to adversely affect the integrity of the enclosure. By surfaces of the apparatus that are above the minimum ignition temperature of the dust concerned. 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. January Replaced By: Specifies general requirements iiec 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 a fire or explosion hazard.
Overview Product Details Many dusts that are generated, processed, handled and stored are combustible. Scame solutions for charging systems. Customers who bought this product also bought BS EN 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.
