30、BS EN 13463-1:2009EN 13463-1:2009 (E) 5 Introduction Non-electrical equipment in accordance with this European Standard means mainly mechanical equipment. The extent of explosion protection and prevention measures applied to mechanical equipment differ from those applied to electrical equipment. Whe
31、reas common electrical equipment working within its design parameters often contains effective ignition sources, this is not true for most mechanical equipment. In most cases, the normal operation of mechanical equipment within its design parameters will not lead to ignition of an explosive atmosphe
32、re. In other words, most mechanical equipment performing its designed duty without malfunctions and with proper maintenance will not produce ignition sources in normal operation. Thus, additional protective measures that are commonly used for electrical explosion protected equipment (e.g. enclosures
33、) are not needed. Even where malfunctions have to be considered, much mechanical equipment can meet the requirements for category 2 equipment by a proper choice of well-tried constructional measures that would reduce failures causing ignition sources to an acceptably low level. Essential to this dec
34、ision is the use of the ignition hazard assessment to evaluate the potential ignition sources of mechanical equipment and under which conditions they will become effective. This is the fundamental difference to standards for electrical equipment. Copyright European Committee for Standardization Prov

36、pment intended for use in potentially explosive atmospheres in air of gas, vapour, mist and dusts. Such atmospheres can also exist inside the equipment. In addition, the external atmosphere can be drawn inside the equipment by natural breathing produced as a result of fluctuations in the equipments
37、internal operating pressure, and/or temperature. This European 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., i.e. equipment built to this European Standard will be satisfactory to any service conditions within this
38、 range unless otherwise specified. NOTE 1 The requirements of this European Standard can also be helpful for the design, construction, testing and marking of equipment intended for use in atmospheres outside the validity range stated above. In this case however, the ignition hazard assessment, ignit
39、ion 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 encounter. It should also be recognized that changes in temperature and pressur
40、e can have a significant influence on ignitability. This European Standard does not cover additional marking for equipment intended for use outside the scope of its validity such as an oxygen-enriched atmosphere. This European Standard is also applicable for the design, construction, testing and mar
41、king of components, protective systems, devices and assemblies of these products which have possible ignition sources and are intended for use in potentially explosive atmospheres. It specifies the requirements for the design and construction of equipment, intended for use in potentially explosive a
42、tmospheres 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. NOTE 2 These are given below: EN 13463-2, Non-electrical equipment for use in potentially explosive atmospheres Prote

EN 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 endangered by firedamp and/or coal dust. NOTE 3 Equipment designed and constructed in accorda
46、nce with this European Standard for a particular category may be used in areas requiring a category with a higher level of safety by the application of additional explosion prevention and/or protection methods. Such applications are not covered in this standard. NOTE 4 Such explosion prevention and/
47、or protection measures include for example inerting, suppression, venting or containment as described in EN 1127-1, for Group II equipment or for example by dilution, drainage, monitoring and shut-down as described in EN 1127-2 for Group I equipment. Such explosion protection methods are outside the
48、 scope of this European Standard.
