BS EN 15181:2017 EN 15181:2017 (E) 6 1 Scope This European Standard specifies the metho

26、d of test for determining the gas energy consumption in gas-fired domestic ovens when they are being used in one or more of the oven cooking modes defined in 3.1. It applies to the gas-fired domestic ovens which are capable of utilizing gases of group H or group E, possibly after conversion accordin

27、g to instructions for use. This European Standard applies to these gas-fired domestic ovens, whether they are separate appliances or component parts of domestic cooking appliances. This European Standard also applies to domestic appliances that can utilize gas and/or electrical energy to provide hea

28、t for cooking when the ovens are utilizing gas energy to provide heat for cooking, but not when electric energy is used to provide any or all of the heat for cooking in the oven. It is not applicable to: microwave combination ovens; small cavities ovens (3.2); oven cavities not provided with devices

29、 to detect and control the temperature for the preparation of food; cooking modes others than defined in 3.1.1 and 3.1.2; ovens connected to a chimney in which the gas energy for cooking provides, by design, also space and/or water heating; appliances designed for use with gases of the third family

30、only. This European Standard is concerned neither with safety nor with overall performance requirements. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

39、le. The instructions for use regarding installation of the oven shall be followed. Prior to every test, the whole appliance (this includes the material and the insulation) shall be at ambient temperature. In multiple cavity appliances, each oven cavity shall be measured separately. Only the cavity m

40、easured shall be switched on. In case an oven has several cooking modes as described in Clause 3, the manufacturer can choose the variant to be tested. This shall be reported (see Clause 8). Unless otherwise specified, measurements are conducted under the following conditions: 5.2 Ambient temperatur

41、e The tests are carried out in a substantially draught-free room in which the ambient temperature is maintained at (23 2) C during the complete test. Prior to the measurement the whole appliance (this includes the material and the insulation) shall be at ambient temperature of (23 2) C. A change in

42、the ambient temperature of the room during the test could affect the results. Care should be taken during the test to ensure that the ambient temperature is as steady as possible. This ambient temperature is measured at a point that is at the same height as the centre of the calculated oven volume o

43、f the oven cavity and at a distance of 0,5 m diagonally from one of the front edges of the appliance; see Figure 1. The measurement of the ambient temperature shall not be influenced by the oven itself or by any other appliance. Dimensions in millimetres Key 1 top view 2 oven 3 thermocouple Figure 1

The primary air adjuster, if any, shall be adjusted according to the technical instructions. Th

45、e appliance is then supplied with G 20, with a composition of at least 95 % methane, at a pressure of 20 mbar. 5.4 Electrical supply The supply voltage shall be maintained at 230 V 1 %. The supply frequency shall be at 50Hz 1 %. 5.5 Load The load for test 7.2 shall be a brick with two holes for temp

46、erature measurements as shown in Annex A. Before using it for the first time a new brick shall be dried in forced air circulation in an oven of about 50 l volume at 175 C for three hours. No more than two bricks shall be dried at the same time in the same oven. The mass m d of the completely dry bri

47、ck without thermocouples shall be measured within 5 min after removal from the oven and shall be noted in grams. The dry mass m d shall be in accordance with the dry mass specified in Annex A. The brick shall be identified with a reference number for accurate calculation of the water absorption acco

Place markings 32 mm from the measuring point of the two thermocouples with steel tube and insert the thermocouples into the holes until the marking matches with the surface of the brick. The thermocouples shall be fixed to ensure that the measuring points remain at a depth of 32 mm

49、during the whole test procedure. The weighing machine should be protected from the effects of the hot brick. The thermocouples may be fixed by means of a droplet of silicon glue at the surface of the brick or by other suitable means. Care should be taken, that the measuring point is the first contact point of the two thermowires. Between test series, the brick should be stored in a refrigerator, preferably not soaked with water. The brick soaking water should be kept away (to reduce dissolving processes); i.e. re-use of the brick sto
