16、by March 1998. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports the essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative annex ZA, which is an integral p
17、art of this standard. This standard applies only to type testing. Items relating to quality assurance systems, production testing and particularly certificates of conformity of auxiliary equipment are not covered by this standard. Particular attention should be paid to the suitability of non-metalli
18、c materials used in the construction of these appliances. A European Standard specifying Requirements for rubber materials for seals and diaphragms for gas appliances and equipment has been prepared by CEN/TC 108 (EN 549). A European Standard for Flexible hose, tubing and assemblies for use with pro

28、ferred to in the body of the text as appliances. This standard covers independent hotplates, including those 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
29、 and their functional sections whether or not the latter are independent or incorporated into an assembly. This standard applies only 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. Appli
30、ances used in leisure vehicles and boats are outside the field of application of this standard. Independent hotplate 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
31、 short periods of time. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequen

It may be one of two types: non-aerated burner, in which the air for combustion is entrained entirely at
38、 the burner outlet; aerated burner, in which part of the air for combustion, termed primary air, is entrained by the gas flow and mixed before the burner outlet. The remainder of the air, termed secondary air, is drawn in after the burner outlet. 3.7 ignition burners Small burners whose flame is des
39、igned to light another burner. They are called pilots in this standard. 3.8 covered burners Hotplate burners where the pans being heated are screened from direct flame contact by the interposition of a surface on which they rest. A covered burner may be: permanent, that is designed to be used only w
