27、09 EN 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. Whereas common ele
28、ctrical 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 atmosphere. In other wo
29、rds, 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) are not neede
30、d. 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 decision is the us
31、e 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. BS EN 13463-1:2009 EN 13463-1:2009 (E) 6 1 Scope This European Stand
32、ard specifies the basic method and requirements for design, construction, testing and marking of non-electrical equipment 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 atmos
33、phere can be drawn inside the equipment by natural breathing produced as a result of fluctuations in the equipments 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 t
34、o + 60 C., i.e. equipment built to this European Standard will be satisfactory to any service conditions within this 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
35、 in atmospheres outside the validity range stated above. In this case however, the ignition hazard assessment, ignition protection provided, additional testing (if necessary), manufacturers technical documentation and instructions to the user, should clearly demonstrate and indicate the equipments s
36、uitability for the conditions it may encounter. It should also be recognized that changes in temperature and pressure 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
37、 oxygen-enriched atmosphere. This European Standard is also applicable for the design, construction, testing and marking 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
38、specifies the requirements for the design and construction of equipment, intended for use in potentially explosive atmospheres 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. N
39、OTE 2 These are given below: EN 13463-2, Non-electrical equipment for use in potentially explosive atmospheres Protection by flow restricting enclosure (fr) EN 13463-3, Non-electrical equipment for use in potentially explosive atmospheres Protection by flameproof enclosure (d) EN 13463-5, Non-electr

41、ed enclosures “p“ (Protection by pressurization described in EN 60079-2 can also be used for non-electrical equipment.) 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 fun
42、ctional in atmospheres endangered by firedamp and/or coal dust. NOTE 3 Equipment designed and constructed in accordance 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
43、and/or protection methods. Such applications are not covered in this standard. NOTE 4 Such explosion prevention and/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, monitor
44、ing and shut- down as described in EN 1127-2 for Group I equipment. Such explosion protection methods are outside the scope of this European Standard. BS EN 13463-1:2009 EN 13463-1:2009 (E) 7 NOTE 5 Although the normal atmospheric conditions above give a temperature range for the atmosphere of - 20
45、C to + 60 C the ambient temperature range for the equipment is - 20 C to + 40 C unless otherwise specified and marked, see 6.2.2. 2 Normative references The following referenced documents are indispensable for the application of this document.
