24、 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 utilising gases of group H or group E, possibly after conversion according to manufacturers instructions. It applies to these gas-fired domestic ovens, w

25、hether they are separate appliances or component parts of domestic cooking appliances. It also applies to domestic appliances that can utilise gas and/or electrical energy to provide heat for cooking when the ovens are utilising gas energy to provide heat for cooking, but not when electric energy is

26、 used to provide any or all of the heat for cooking in the oven. It is not applicable to: microwave combination ovens; small cavity ovens (3.2); ovens without adjustable temperature control; cooking modes others than defined in 3.1.1 and 3.1.2; ovens connected to a chimney in which the gas energy fo

27、r cooking also, by design, provides space and/or water heating; appliances designed for use with gases of the third family only. This standard is concerned neither with safety nor with performance requirements. 2 Normative references The following referenced documents are indispensable for the appli

33、ens oven with the following dimensions related to the usable volume: both width and depth 175 C for three hours. No more than two bricks shall be dried at the same time in the same oven. The mass md of the completely dry brick without thermocouples shall be measured within 5 min after removal from t

34、he oven and shall be noted in grams. The dry mass mdshall 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 according to 7.2.2. Place markings 32 mm from the measuring point of the two therm

35、ocouples 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 during the whole test procedure. NOTE 1 The weighing machine should be protect

36、ed from the effects of the hot brick. NOTE 2 The thermocouples may be fixed by means of a droplet of silicon glue at the surface of the brick or by other suitable means. NOTE 3 Care should be taken that the measuring point is the first contact point of the two thermowires. NOTE 4 Between test series

37、 the brick should be stored in a refrigerator, preferably not soaked with water. The brick soaking water should be kept (to reduce dissolving processes); i.e. re-use of the brick storage water. A brick that has already been soaked in water needs at least eight hours to dry out as described above. NO

38、TE 5 Due to the porosity of the brick care should be taken that the holes of the brick are not enlarged if the thermocouples are removed and reinserted. NOTE 6 A brick can be used for about 20 tests when handled with normal care. 5.6 Instrumentation Air temperature measurements in the empty oven are

39、 made with a thermocouple with a welded point (not with a black copper plate), class 1, type K. Room temperature measurements are made with a thermocouple, class 1, type T. NOTE 1 Other types of thermocouple may be used for the measurement of room temperatures provided they are known to provide equi

40、valent or better accuracy and reproducibility than a type T. Temperature measurements in the load are made with two thermocouples with 1 mm steel tube diameter, class 1, according to EN 60584-2. The thermocouple shall be accurate to + 1,5 K. NOTE 2 The steel tube of the thermocouple eases the insert

41、ion of the thermocouple into the brick. See also NOTE 2 in 5.5.

The determination of the heat input and the consumption shall be made at an accuracy as defined in EN 30-1-1:2008, Subclause 7.3.1.2.1.1. The equipment used shall be capable of measuring the following parameters with the specified accurac

43、ies: Auxiliary electrical energy within + 1,5 % or + 10 Wh of the measured value, whichever is the greater; Voltage within 0,5 %; Frequency within 0,5 %; Mass within 3 g; Time within 5 s. 5.7 Positioning of the appliance The appliance shall be installed according to the manufacturers instructions an

44、d in accordance with 7.1.3.2 of EN 30-1-1:2008, EN 30-1-2:1999 and EN 30-1-4:2002, as applicable. 5.8 Auxiliary electrical energy The auxiliary electrical energy as defined in Subclause 3.4 is measured during the brick test (Subclause 7.2.3). The measurement is taken over the same period of time as

45、the gas consumption measurement at the temperature Ti.2 of Table 1. 6 Useful oven volume The useful oven volume is measured in accordance with 3.4.3.12 of EN 30-1-1:2008. The useful volume is rounded to the nearest whole litre. 7 Energy consumption and time 7.1 Measurement of oven temperature The ov

46、en temperature of each cooking mode as appropriate (see Clause 3) shall be measured separately. During the test only one cooking mode (see Clause 3) shall be used. The air temperature in the empty oven is measured with a thermocouple according to 5.6 fixed to the grid which is delivered with the ove

47、n and placed in the oven in a way that the welded point of the thermocouple is located at the centre of the useful volume of the oven with a distance of at least 30 mm from the grid. 7.2 Energy consumption and time for heating a load 7.2.1 Purpose The purpose of this test is to measure the energy co

48、nsumption and the time for heating a load. The load is a water saturated brick as defined in 7.2.2 which simulates both the thermal properties and the water content of food (e.g. meat).
