scope:

This European Standard specifies the explosion protection requirements for the construction and marking of equipment that may be an individual item or form an assembly. This includes machines and systems formed by interconnected combinations of separately assessed equipment and components placed on the market by a single manufacturer and also components intended for use in mines susceptible to explosive atmospheres of firedamp and/or combustible dust. NOTE 1 - This European Standard deals only with the ignition control aspects of mining machinery and manufacturers have to take account of all other relevant EU Directives relating to the construction of machines e.g. the consolidated Machinery Directive 98/37/EC. Additionally, manufacturers have to take account of any national legislation in the country where they intend to market their equipment. NOTE 2 - Where the flammable gas in the atmosphere is not predominantly methane, a reference is required to 4.1 of EN 60079-0:2004 or EN 13463-1:2001. NOTE 3 - The definition of �equipment� is contained in EN 13463-1. Equipment complying with the relevant clauses of this standard is considered to meet the requirements for equipment of Group I - Category M2. This European Standard also deals with the prevention of ignitions of explosive atmospheres caused by burning (or smouldering) of combustible material such as fabric fibres, plastic O�rings, rubber seals, lubricating oils or greases used in the construction of the equipment if such items could be an ignition source. For example, the mechanical failure of rotating shaft bearings can result in frictional heating that ignites its plastic retaining ring, plastic seal or lubricating grease.
