ÖNORM EN 1710

When drafting this European Standard, it has been assumed that equipment and components are: designed in accordance with good engineering practice, taking account of expected shocks,vibrations and failure modes; of sound mechanical and electrical construction; made of materials with adequate strength and of suitable quality; free from defects and are kept in good repair and working order, e.g. so that the required dimensions remain within permissible tolerance despite wear. 1 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 machinery and components placed on the market by a single supplier for use in mines susceptible to explosive atmospheres of firedamp and/or combustible dust (at atmospheric conditions as defined in EN 1127-2). NOTE 1 This European Standard deals only with the ignition protection of mining machinery and manufacturers will need 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 will need 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, reference will need to be made to 4.1 in either EN 60079-0:2004 or EN 13463-1:2001. NOTE 3 The definition of equipment is contained in EN 13463-1. The definition of assembly can be found the ATEX guidelines, published by the European Commission. Equipment complying with the relevant clauses of this European 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 f (...abbreviated)
