ADDITION: This European Standard specifies requirements for the construction and operating characteristics relating to the safety, rational use of energy and marking, of atmospheric commercial gas heated open burners, covered burners, non-enclosed covered burners. It also states test methods to check those characteristics. This European Standard only covers type testing. 2 Normative references ADDITION: EN 203-1:2005, Gas Heated Catering Equipment - Part
: General safety rules EN 631-1, Materials and articles in contact with foodstuffs - Catering containers. Part 1: Dimensions of containers 3.3.2.101 open burner 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 3.3.2.102 non-enclosed covered burner burner 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. All products of combustion are evacuated directly to the atmosphere, e.g. around the periphery of the plate. The burner is designed so that partial visibility of the flame is possible in normal operation. A non-enclosed burner may be: -
permanent, i.e. designed to be used only with the plate in position;
- dual purpose, i.e. designed so that it may also be used as an open burner after removal of the removable plate. 3.3.2.103 wok burner open burner for which the environment and in particular the supports to accept the cooking utensils are specifically nominated by the manufacturer 3.3.101 working surface surface on which the pans rest or the food is handled as well as the top horizontal surface of the appliance 5.1.6 Supply of combustion air and evacuation of combustion products ADDITION: Appliances shall be constructed so that, under normal conditions of use and maintenance, the supply of combustion air and the evacuation of combustion products is permanently guaranteed. Obstruction of the combustion air inlets and the evacuation of the products of combustion shall be made impossible (from the pans used).

7.4.3.101 Covering of several burners In the case of a possible covering of several burners by the same pan, a series of tests is carried out with the largest pan recommended by the manufacturer. 7.6.2.101 Open burners Each burner supplied and adjusted under the conditions of 7.6.2.1 of EN 203-1:2005, is successively
covered by the largest pan which can be placed on the appliance, similar to those defined in table 102 and figure 101. The products of combustion shall be sampled using the corresponding ring defined in table 103 and figure 102. If in this position the flame comes in contact with the ring, it is adjusted in height to avoid disturbance of the flame, and to conserve the level of sampling of CO2 similar to that defined in EN 203-1. In the case of open burners, the burners adjoining the burner under test can be covered by pans of a diameter smaller than that corresponding to the output, however, pans with the biggest possible diameter shall be used. Distance between the pans and between the pans and the rings shall be at least 1 cm.
