Although they are not covered by this standard, the requirements of this standard are applicable to appliances that may be used inside habitations which, in addition, shall have a heat input not exceeding 4,2 kW and comply with EN 449. These appliances are for use exclusively with gases of the third family as defined in Clause 4. This European standard applies to appliances that have a nominal heat input not exceeding 17 kW (based on the gross calorific value); – fixed or, – movable, including those which comprise a housing for a transportable and rechargeable liquefied petroleum gas cylinder.

This European standard does not cover LPG containers for liquefied petroleum gas, neither their associated regulator nor tubing and flexible hoses which shall comply with national requirements in force. This European standard does not lay down any specific requirements for the thermal efficiency of this type of appliances, but the requirements relating to combustion, which is a safety matter, ensure that the gas fuel will burnefficiently. However a method to measure the performance is described in informative Annex C. This standard does not apply to appliances covered by EN 416-1, EN 419-1, EN 449, EN 461 and EN 521.
