Organization: IEC
Publication Date: 1 July 2004
Status: inactive
Page Count: 108
ICS Code (Electrical apparatus for explosive atmospheres): 29.260.20
scope:

This part of IEC 61241 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.

This standard is supplemented or modified by the following parts of IEC 61241 concerning specific types of protection:

- Part 1: Protection by enclosures 'tD'

- Part 2: Protection by pressurization 'pD' (under consideration)

- Part 11: Intrinsically safe apparatus 'iD'

- Part 18: Protection by encapsulation 'mD'

NOTE IEC 61241-14 gives guidance on the selection and installation of the apparatus. Apparatus within the scope of this standard may also be subjected to additional requirements in other standards - for example, IEC 60079-0.

The application of electrical apparatus in atmospheres which may contain explosive gas as well as combustible dust, whether simultaneously or separately, requires additional protective measures.

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. The method used is not to adversely affect the integrity of the enclosure.

This standard does not apply to dusts of explosives that do not require atmospheric oxygen for combustion, or to pyrophoric substances.

This standard is not applicable to electrical apparatus intended for use in underground parts of mines as well as those parts of surface installations of such mines endangered by fire damp and/or combustible dust.

This standard does not take account of any risk due to an emission of flammable or toxic gas from the dust.

intended Use:

The manufacturer shall specify in the documents submitted according to 23.2 the entries intended for use with cable or conduit, their position on the apparatus and the maximum number permitted.
