19、cation of an identical text or by endorsement, at the latest by May 2000, and conflicting national standards shall be withdrawn at the latest by May 2000. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and sup
20、ports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this standard. According to the CENLENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this
21、European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Page 5 EN 509 : 1999 1 Scope This European Standard specifies the requirements and te
22、st methods for the construction, safety, and marking of decorative fuel effect gas appliances not exceeding a nominal heat input of 20 kW, (based on the net calorific value), thereafter referred to as appliances. This standard is applicable to appliances that are designed to simulate a solid fuel fi
23、re and incorporate a natural draught burner with or without an ignition burner. The appliances are for decorative purposes only and are not heating appliances. This standard is applicable to type BAS, as described in 4.2.2, decorative fuel effect gas appliances that are designed to be installed with
24、in a non-combustible builders opening or a non- combustible fireplace recess. in addition, this standard is applicable to decorative fuel-effect gas appliances that are designed to be installed under a non-combustible canopy which may be independent or integral with a flue box, for which additional
25、requirements are specified in annex C. This standard is not applicable to: - catalytic combustion appliances; - appliances in which the supply of combustion air andor the evacuation of products of combustion is achieved by mechanical means. This standard is only applicable to appliances which are in
26、tended to be type tested. Matters related to quality assurance systems, tests during production and to certificates of conformity of auxiliary devices are not dealt with by this standard. Requirements concerning the rational use of energy have not been included in this European Standard because the
27、appliances are for decorative purposes. 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 refere
28、nces, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

33、Decorative fuel effect gas appliances 3.1.1 decorative fuel effect gas fire (see figure 1): An appliance designed to simulate a solid fuel appliance for decorative purposes and intended to be installed so that the products of combustion pass unrestricted from the firebed to the chimney or flue. 3.1.
34、2 working surfaces: These include those parts of an appliance which, due to the nature of the appliance, have temperatures exceeding the limits specified in 6.4.1. Examples are: - Bricks, refractories, imitation fuel; - Fire fronts; - Fire baskets; - Canopies, burners, burner trays and bracketry. Wo
35、rking surfaces do not include that part of any surface within 25 mm of parts that have to be touched or removed during normal operation of the appliance. 3.2 Gases 3.2.1 reference conditions: - for calorific values, temperature: 15 OC; - for gas and air volumes dry, brought to 15 “C and an absolute
36、pressure of 1 013,25 mbar. Page 8 EN 509 : 1999 3.2.2 calorific value: The quantity of heat produced by the combustion, at a constant pressure of 1 O1 3,25 mbar, of unit volume or mass of gas, the constituents of the combustible mixture being taken at reference conditions and the products of combust
37、ion being brought back to the same conditions. A distinction is made between: - the gross calorific value in which the water produced by combustion is assumed to be condensed: Symbol: H, - the net calorific value in which the water produced by combustion is assumed to be in the vapour state; Symbol:
38、 H, Units: either: - megajoules per cubic metre (MJ/m3) of dry gas at the reference conditions; or - megajoules per kilogram (MJkg) of dry gas. EN 437: 19931 3.2.3 relative density: The ratio of the masses of equal volumes of dry gas and dry air at the same conditions of temperature and pressure. Sy
39、mbol: d 32.4 Wobbe index: The ratio of the calorific value of a gas per unit volume and the square root of its relative density under the same reference conditions. The Wobbe index is said to be gross or net according to whether the calorific value used is the gross or net calorific value. Symbol: g
40、ross Wobbe index: W, net Wobbe index: Wi Units: either: - megajoules per cubic metre (MJ/m3) of dry gas at the reference conditions, or - megajoules per kilogram (MJkg) of dry gas. EN 437: 19931 Page 9 EN 509 : 1999 3.2.5 test pressures: Gas pressures used to verify the operational characteristics o
41、f appliances using combustible gases. They consist of normal and limit pressures. They are expressed in millibar (mbar). NOTE: 1 mbar = 100 Pa. 3.2.6 normal pressure: The pressure under which appliances operate in .nominal conditions, when they are supplied with the corresponding reference gas. Symb
42、ol: pn. 3.2.7 limit pressures: Pressures representative of the extreme variations in the appliance supply conditions. Symbols: maximum pressure: pmax minimum pressure: Pmin 3.2.8 pressure couple: Combination of two distinct gas distribution pressures applied by reason of the significant difference e
43、xisting between the Wobbe indices within a single family or group in which: - the higher pressure corresponds only to gases of low Wobbe index; and - the lower pressure corresponds to gases of high Wobbe index. EN 437: 19931 3.3 Appliance construction 3.3.1 The gas circuit 3.3.1.1 inlet connection:
44、The part of the appliance intended to be connected to the gas supply. 3.3.1.2 mechanical joint: A connection device assuring soundness in an assembly of several parts, generally of metal. NOTE: For example the following: - cone seated joints; - torroidal sealing rings (O rings); Page 10 EN 509 : 199
45、9 - flat joints; - metal to metal joints. 3.3.1.3 gus circuit: The part of the appliance that conveys or contains the gas between the appliance gas inlet connection and the burner( s). 3.3.1.4 gus restrictor: A non-adjustable device which is placed in the gas circuit so as to create a pressure drop
46、and thus reduce the gas pressure at the burner to a predetermined value for a given supply pressure and rate. 3.3.1.5 gus rate adjuster: A component intended for the manufacturer or installer to set the gas rate to each burner at a predetermined value according to the supply conditions. The adjustme
47、nt may be progressive (screw adjuster) or discontinuous (changing restrictors). The adjuster of an adjustable governor is regarded as a gas rate adjuster. The action of setting this device is called setting the gas rate. 33.1.6 gus rate control: A component allowing the user to open or close the gas
48、 supply to one or more burners. It may also be used to adjust the gas rate of certain burners to a predetermined value, called the reduced rate. This device may be a tap. 3.3.1.7 injector: A component that admits the gas into a burner. 33.1.8 start-gas: The initial quantity of gas ignited to give a
49、flame which is used to ignite the main burner. It may be discharged through a separate ignition burner or part of the main burner. 33.2 Burner 3.3.2.1 main burner: A burner which assures the function of the appliance. It is usually called simply “burner“. 33.2.2 pun burner: A main burner which utilizes a particulate medium (e.g. sand) for the distribution of gas over a defined area. 3.3.2.3 ignition burner: A separate burner intended to light the main burner. 3.3.2.3.1 permanent ignition burner: An ignition burner that operates continuously throughout the whole peri
