Clause 3 of EN 203-1:2021 applies with the following additions:
3.101 Terminology referring to type of appliances
3.101.1
open burner
appliance with hot plate burner for which the pan is heated directly by the flame and the products of
combustion are evacuated directly to atmosphere without following a specific way
3.101.2
non-enclosed covered burner
appliance with burner, designed so that partial visibility of the flame is possible in normal operation, and for
which the pan or the foodstuffs being heated is screened from direct flame contact by the interposition of a
surface on which they rest and where all products of combustion are evacuated directly to the atmosphere
(e.g. around the periphery of the plate)
Note 1 to entry: A non-enclosed covered burner may be:
— permanent, i.e. designed to be used only with the plate in position;
