BS EN 13203-2:2015EN 13203-2:2015 (E) 5 Introduction The
24、 safety operation of the boiler or water heater is not covered by this standard. Safety should be proved by means of the essential safety requirements of the Gas Appliances Directive 2009/142/EC. This may be achieved by compliance with the appropriate existing harmonized standards. NOTE Useful stand
25、ards are EN 26, EN 89, EN 15502-1, EN 15502-2-1 and EN 15502-2-2. BS EN 13203-2:2015EN 13203-2:2015 (E) 6 1 Scope This European Standard is applicable to gas-fired appliances producing domestic hot water. It applies to both instantaneous and storage tank appliances; waters-heaters and combination bo
26、ilers that have: a heat input not exceeding 70 kW; and a hot water storage tank capacity (if any) not exceeding 500 l. In the case of combination boilers, with or without storage tank, domestic hot water production is integrated or coupled, the whole being marketed as a single unit. EN 13203-1 sets
27、out in qualitative and quantitative terms the performance in delivery of domestic hot water for a selected variety of uses. It also gives a system for presenting the information to the user. The present document sets out a method for assessing the energy performance of the appliances. It defines a n
28、umber of daily tapping cycles for each domestic hot water use, kitchen, shower, bath and a combination of these, together with corresponding test procedures, enabling the energy performances of different gas-fired appliances to be compared and matched to the needs of the user. Where other technologi
29、es are combined with a gas-fired boiler or a water heater to produce domestic hot water, specific parts of EN 13203 apply. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references,
30、 only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. Not applicable. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 storage tank reservoir for domestic hot
31、 water 3.2 nominal domestic hot water heat input (Qnw) value of the heat input for the production of domestic hot water stated in the instructions Symbol: Qnw Unit: kilowatt (kW) 3.3 summer mode conditions during which the appliance supplies energy only for the production of domestic hot water 3.4 w
32、inter mode conditions during which the combination boiler supplies energy for the production of domestic hot water and space heating 3.5 domestic water test temperature temperature of the delivered water at which the tests are conducted BS EN 13203-2:2015EN 13203-2:2015 (E) 7 3.6 control cycle the t
33、ime cycle for keeping components and/or the storage tank (if any) of the domestic hot water circuit at predetermined temperature level, consists of an ON duration time during which the heating of the domestic hot water (by gas energy and/or auxiliary energy) is operating, and an OFF duration time du

40、eneral test conditions 4.1 Reference conditions Unless otherwise stated, the general test conditions shall be as follows: cold water temperature: 10 C; maximum average variation over the test period: 2 K; cold water pressure: (2 0,1) bar; ambient air temperature: 20 C; maximum average variation over
41、 the test period 1 K; maximum variation during the tests 2 K; electrical supply voltage: (230 2) V (single phase). 4.2 Measurement uncertainties Except where otherwise stated in the clauses describing the tests, the uncertainties of measurements carried out shall be not greater than the maximum unce
42、rtainties indicated below. The standard deviations shall be evaluated taking account of the various sources of uncertainty: contribution from the instrument, repeatability, calibration, ambient conditions, etc. water rate: 1 %; gas rate: 1 %; time: 0,2 s; temperatures: ambient: 1 K; water: 0,5 K; ga
43、s: 0,5 K; mass: 0,5 %; gas pressure: 1 %; gas calorific value: 1 %; gas density: 0,5 %; electrical energy: 2 %. The stated measurement uncertainties relate to individual measurements. For measurements that combine a number of individual measurements, smaller uncertainties on the individual measureme
44、nts may be necessary to ensure a total uncertainty within 2 % under the steady state conditions. These uncertainties correspond to two standard deviations (2). BS EN 13203-2:2015EN 13203-2:2015 (E) 9 4.3 Test conditions 4.3.1 General Except where otherwise stated, the appliance is tested under the f
45、ollowing conditions. For combination gas boiler, the tests shall be carried out only in summer mode as defined in 3.3, and the appliance shall be set in summer mode. For all tests defined by this standard, the same adjustment of the appliance shall be maintained. 4.3.2 Test room The appliance shall
46、be installed in a well-ventilated, draught-free room (air speed less than 0,5 m/s). The appliance shall be protected from direct solar radiation and radiation from heat generators. 4.3.3 Water supply For the tests: the domestic water pressure is the static inlet pressure under dynamic conditions mea
47、sured as close as possible to the appliance; the inlet and outlet temperatures of the domestic water shall be measured in the centre of the flow and as close as possible to the appliance. The inlet temperatures shall be measured immediately upstream of the water inlet connection. Except where otherw
48、ise stated, the outlet temperatures shall be measured immediately downstream of the outlet connection or, in the case of an appliance with spout delivery, by means of an immersed temperature measuring device, e.g. a u-tube fitted at the outlet of a tube of the same length as the minimum length of th
49、e spout normally supplied together with the appliance. The hot water temperature shall be measured with a rapid response temperature sensor. “Rapid response temperature sensor“ means a measuring instrument with a response time such that 90 % of the final temperature rise, from 15 C to 100 C, is obtained within about 1 s, when the sensor is plunged into still water. 4.3.4 Steady state Steady state operating conditions shall be regarded as established when the appliance opera
