Foreword
This document (EN 203-2-3:2014) has been prepared by Technical Committee CEN/TC 106 “Large kitchen
appliances using gaseous fuels”, the secretariat of which is held by AFNOR.
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text or by endorsement, at the latest by June 2015 and conflicting national standards shall be withdrawn at the
latest by June 2016.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 203-2-3:2005.
The technical changes in comparison to the previous edition are:
− in 5.1.5.2, clarification on type A and type B appliances;
− revision of 5.1.101 on flexibles hoses and/or rotating connections;
− addition of a paragraph in 5.3.1 food spillage;
− revision of 5.3.2.101 on tilting boiling pans;
− addition of motorized cover in 5.3.2.102;
− revision of 5.3.2.103 on boiling pans fitted with stirrers and/or mixers;
− addition of a filling level in 5.3.101;
− revision of 6.8.2 on pressurized parts;
− revision of 7.2.101 on soundness of gas circuits;
− addition of 7.2.102 on soundness of the combustion product circuits for tilting pans;
− addition of burners with sequential controls in 7.6.2.101;
− modification of the requirements for the stability and mechanical safety of tilting parts in 7.8.3.
This European Standard specifies the test methods and safety and rational use of energy requirements for
boiling pans.
This European Standard has to be used in conjunction with EN 203-1. This document refers to Clauses of
EN 203-1:2014 or adapts Clauses by stating “with the following modification”, “with the following addition”, “is
replaced by the following” or “is not applicable” in the corresponding Clause. This European Standard adds
