BS EN 13463-1:2009 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
atmosphere can be drawn inside the equipment by natural breathing produced as a result of fluctuations in the
equipment?s internal operating pressure, and/or temperature.
BS EN 13463-1:2009 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 BS EN 13463-1:2009 will be
satisfactory to any service conditions within this range unless otherwise specified.
NOTE 1 The requirements of BS EN 13463-1:2009 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, ignition protection provided, additional testing (if necessary), manufacturer?s technical
documentation and instructions to the user, should clearly demonstrate and indicate the equipment?s suitability for the
conditions it may encounter. It should also be recognized that changes in temperature and pressure can have a significant
influence on ignitability.
BS EN 13463-1:2009 does not cover additional marking for equipment intended for use outside the scope
of its validity such as an oxygen-enriched atmosphere.
BS EN 13463-1:2009 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.
BS EN 13463-1:2009 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. BS EN 13463-1:2009 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 - 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-electrical equipment for use in potentially explosive atmospheres - Protection by
constructional safety (c)
EN 13463-6, Non-electrical equipment for use in potentially explosive atmospheres - Protection by control
of ignition sources (b)
EN 60079-2, Electrical apparatus for explosive gas atmospheres - Pressurised 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 functional 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
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, monitoring and shutdown
as described in EN 1127-2 for Group I equipment. Such explosion protection methods are outside the scope of this
European Standard.
NOTE 5 Although the normal atmospheric conditions above give a temperature range for the atmosphere of - 20 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.
