30、European Standard has been prepared by Technical Committee CEN/TC 305, Potentially explosive atmospheres Explosion prevention and protection, the Secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text o
31、r by endorsement, at the latest by May 2002 and conflicting national standards shall be withdrawn at the latest by May 2002. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association and supports essential requirements of
32、 EU Directive(s). For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this standard. Annexes A and C are normative. Annexes B and D are informative. This standard includes a bibliography. According to the CEN/CENELEC Internal Regulations, the national standa
33、rds organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

35、ded for use in potentially explosive atmospheres in air of gas, vapour, mist and dusts. This standard is valid for atmospheres having pressures ranging from 0,8 bar to 1,1 bar and temperatures ranging from 20 C to +60 C. Such atmospheres can also exist inside the equipment. The external atmosphere c
36、an be drawn inside the equipment by natural breathing, produced as a result of fluctuations in the equipments internal operating pressure and/or temperature. This standard can also be helpful for the design, construction, testing and marking of equipment intended for use in atmospheres outside the v
37、alidity range stated above but in this case, the ignition risk assessment, ignition protection provided, additional testing (if necessary), manufacturers technical documentation and instructions to the user, should clearly demonstrate and indicate the equipments suitability for the conditions it may
38、 encounter. NOTE 1 This standard does not cover additional marking for equipment intended for use outside the scope of its validity such as an oxygen-enriched atmosphere. It specifies the requirements for the design and construction of equipment, intended for use in potentially explosive atmospheres
39、 in conformity with all categories of Group I and II. This European Standard can be supplemented by European Standards concerning the specific types of ignition protection currently in preparation. NOTE 2 These standards are given below: prEN 13463-2, Non-electrical equipment for use in potentially
40、explosive atmospheres Protection by flow-restricting enclosure (fr). prEN 13463-3, Non-electrical equipment for use in potentially explosive atmospheres Protection by flame-proof enclosure (d). prEN 13463-4, Non-electrical equipment for use in potentially explosive atmospheres Protection by inherent
41、 safety (g ). prEN 13463-5, Non-electrical equipment for use in potentially explosive atmospheres Protection by constructional safety (c). prEN 13463-6, Non-electrical equipment for use in potentially explosive atmospheres Protection by control of ignition sources (b). prEN 13463-7, Non-electrical e
42、quipment for use in potentially explosive atmospheres Protection by pressurization (p). prEN 13463-8, Non-electrical equipment for use in potentially explosive atmospheres Protection by liquid immersion (k). EN 50303, Group I, category M1 equipment intended to remain functional in atmospheres endang
43、ered by firedamp and/or coal-dust. NOTE 3 Where it is impracticable to avoid all effective sources of ignition, explosion protection can also be achieved by, e.g. inerting, suppression, venting or containment as described in EN 1127-1 for Group II equipment or for example by dilution, drainage, moni
44、toring and shut-down as described in prEN 1127-2 for Group I equipment. Such explosion protection methods are outside the scope of this standard. NOTE 4 This European Standard specifies methods of controlling the risk of ignition of explosive atmospheres by equipment. These cannot be sufficient for
45、some types of powder-handling equipment that create a dust cloud inside an enclosure during normal operation. In such cases, one or more of the protective systems described in 6.5 of EN 1127-1:1997 should be adopted. The means adopted for limiting the effects of ignitions in mining systems are descr
46、ibed in 6.5 of prEN 1127-2:2001. Equipment protected in this way is outside the scope of this standard.
