This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free We Association, and supports the essential r
16、equirements of EU Directive(s). For relationship with EU Directive(s), see informative annex ZA, which is an integrai part of this standard. This standard applies only to type testing. Items relating to quality assurance systems, production testing and particularly certificates of conformity of awlm

27、teristics, safety specifications and rational use of energy, relevant test methods and marking of independent hotplates, including those fitted with a grill, burning liquefied petroleum gas, referred to in the body of the text as appliances. This standard covers independent hotplates, including thos
28、e fitted with a grill as defined in 3.39, used outdoors and operating with the gases indicated in 4.1 and according to the categories specified in 4.2. This standard applies to these appliances and their hctional sections whether or not the latter are independent or incorporated into an assembly. Th
29、is standard applies oniy to type testing. Appliances supplied with third family gas at pressures greater than those defined in 4.2 are outside the field of application of this standard. Appliances used in leisure vehicles and boats are outside the field of application of this standard. Independent h
30、otplate burners, whose nominal heat input is below 1,16 kW, and grills are not subject to any special requirement concerning the rational use of energy due to their low rate and their use for short periods of time. 2 Normative references This European Standard incorporates, by dated or undated refer
