Electrical apparatus for use in the presence of combustible dust Part This standard describes the safety features of these types of explosion protection techniques and specifies the installation procedures to be adopted. This standard does not apply to dusts of explosives that do not require atmospheric oxygen for combustion, or to pyrophoric substances.

When ignited they can burn rapidly and with considerable explosive force if mixed with air in the appropriate proportions. By surfaces of the apparatus that are above the minimum ignition temperature of the dust concerned.
Equipment protection by increased safety “e”. Protection by intrinsic safety ‘iD’. Click to learn more. It is most important that the correct selection and installation procedures be followed to ensure the safe use of electrical apparatus in hazardous areas.
Scame solutions for charging systems. When electrical apparatus is used in locations where combustible materials are present, it is important that suitable precautions are taken.
Specifies general requirements for the design, construction, testing and marking of electrical apparatus ied by any recognized safeguard technique for use in areas iex combustible dust may be present in quantities that could lead to a fire or explosion hazard. 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 a fire or explosion hazard.
BS EN 61241-0:2006
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.

To reduce the likelihood of ignition of the external explosive atmosphere, all such electrical apparatus should be adequately protected. All International European Italian. Several techniques are available for the explosion protection of electrical apparatus in hazardous areas.
Generally, electrical safety is ensured by the implementation of one of two considerations, i. Only in cases specifically mentioned, the requirements differ for Categories 1D, 2D and 3D. Compliance with this standard will only provide the required level of safety if the electrical apparatus is operated within its rating and is installed and maintained according to the relevant codes of practice or requirements, for example in respect of protection against overcurrents, internal short-circuits, and other electrical faults.
Your basket is empty. By discharge of an accumulated electrostatic charge. 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. 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 61241–0 divided into three zones according to the level of risk. Learn more about the cookies we use and how to change your settings.
