DIN EN 13203-2:2015-08 EN 13203-2:2015 (E) 5 Introduction The safety operation of the boiler o
28、r 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 standards are EN 26, EN 89, EN 15502-1
29、, EN 15502-2-1 and EN 15502-2-2. DIN EN 13203-2:2015-08 EN 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 boilers that have: a heat inpu
30、t 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 out in qualitative and quant
31、itative 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 number of daily tapping cycle
32、s 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 technologies are combined with a gas-f
33、ired 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, only the edition cited appl
34、ies. 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 water 3.2 nominal domestic

44、ions 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 the test period 1
45、 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 uncertainties indicate
46、d 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; gas: 0,5 K; mass: 0,
47、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 measurements may be necessa
48、ry to ensure a total uncertainty within 2 % under the steady state conditions. These uncertainties correspond to two standard deviations (2).
