The corresponding position of the adjusting device or the corresponding value of the burner pressure is noted. The burner is then cooled prior to proceeding to the following test in accordance wi

For the fi

34、, the test will be carried out using a pan with the next lower diameter (260 mm, 240 mm or 220 mm), containing the corresponding quantity of water (6,1 kg, 4,8 kg or 3,7 kg). In that case the burner heat input will be adjusted to 2,36 kW, 1,98 kW or 1,64 kW respectively, to 2 %, using the method des

35、cribed in EN 301-1:2008+A3:2013, 7.3.1.2.1.1 a). The initial temperature of the water t1shall be (20 1) C, and the temperature at the time of extinction of the burner shall be (90 1) C. The maximum temperature t2observed after extinction of the burner (final temperature expressed in degrees Celsius)

36、 is measured. The temperature sensor is placed in the centre of the volume of water and the temperature is measured using a sensor, the measurement uncertainty of which is less than 0,1 C. The burner is pre-heated under the following conditions: the burner is operated for 10 min at its nominal heat

37、input or at the input adjusted according to Table 1, in the adjustment position defined and noted in 5.1.1; whatever the nominal heat input is the burner is covered with the 220 mm diameter pan containing 3,7 kg of water. Once preheating is completed the 220 mm diameter pan is withdraw and immediate

38、ly afterwards is replaced by the pan used for the efficiency test. The measurement of the gas consumption then begins and stops after the extinction of the burner, the pan staying in place. The efficiency is calculated using the formula: 100theoricgas burnergas burnerEEEE= BS EN 30-2-1:2015EN 30-2-1

46、ith 5.2.1, the pan corresponding to the nominal heat input of the burner being tested containing the corresponding mass of water, is placed at the most appropriate point on the hot plate. NOTE For this test, footnote a of Table 1 is not applicable. The smallest number of pans of the largest possible

47、 diameter, selected from Table 1, and containing the corresponding masses of water are placed on the remaining surface area, if any, of the hot place. The temperature is determined in the same manner as for an uncovered burner: the initial water temperature t1being 20 C 1 C, the final temperature t2

48、for each pan is the highest temperature observed after extinction of the burner, which takes place as soon as the water temperature of any of the pans reaches 90 C 1 C. The test is carried out at the nominal heat input, with the burner adjusted in accordance with 5.1.1. The efficiency is the ratio o

49、f the sum of the quantities of heat absorbed by the pans and the water which they contain and the quantity of heat consumed at the burner (see formula in 5.2.1). This first test is carried out starting from cold, a second test is carried out, starting from hot. It is assumed that the hot plate is hot when the water contained in the largest pan used for the efficiency test, used on its own, has been brought to boiling point. When the plate is hot, the pans are withdrawn. The test is then carried out under the same condi
