European foreword
This document (EN 1-2:2025) has been prepared by Technical Committee CEN/TC 46 “Fireplaces for
liquid fuels”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by November 2025, and conflicting national standards shall
be withdrawn at the latest by February 2027.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 1:1998 and EN 1:1998/A1:2007.
In relation to EN 1:1998 and EN 1:1998/A1:2007, the following technical changes have been made:
— completely revised according to the requirements of M/577;
— energy efficiency and energy class labelling and seasonal space heating efficiency added;
— requirements for environmental sustainability added.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
