適用范圍：This European Standard specifies the requirements, the test methods and the marking of domestic flueless spaceheaters, including diffusive catalytic combustion heaters, having a nominal heat input (Hs), not exceeding 4,2 kWburning 3rd family gases at nominal operating pressures not exceeding 50 mbar, referred to in the text as'appliances'.This European Standard is applicable to the following types of appliances:a) fixed heaters burning commercial butane and/or commercial propane;b) portable or mobile heaters burning either commercial butane, or, commercial butane and commercial propaneincluding those that incorporate a LPG container installation compartment for a transportable refillable liquefiedpetroleum LPG container.There are no specific thermal efficiency requirements appropriate to these types of appliance as:c) all the heat produced by the combustion process is released into the space to be heated;d) the requirements with regard to the combustion performance, which is a safety matter, ensure the effectiveburning of the fuel gas.It does not cover appliances incorporating electrically operated gas control systems.Annex A gives the details of the categories of appliances marketed in various countries.Requirements for appliances given in this standard assume that the supply of gas from the container will begoverned by a pressure regulator having a maximum nominal outlet pressure of 50 mbar.This European Standard does not cover LPG containers for liquefied petroleum gas neither their associatedregulator nor tubing and flexible hoses which shall comply with national requirements in force.This European Standard only covers type testing.
