7 Test procedure
7.1 Environmental conditions
7.2 Heating Temperature
12 7.2.1 The thermometers to measure temperature are attached at the selected measuring points. Each thermometer with copper disk is fixed by means of thin adhesive tape to not place between the test specimen and the thermometer.
7.2.2 The test specimen is covered with a sheet of thermal insulation. The cover sheet has a thickness of (7 ± 1) mm. The size of the cover sheet is such that the edges extend at least 20 mm beyond the outline of the heating area of the test specimen.
7.2.3 Check the temperature of specimens is constant at the environment temperature (20,0 ± 2,0) C.
7.2.4 -Turn on the heating device of the test specimen and measure the temperature of each measuring point at intervals of at least 1 min.
7.2.5 The measurement duration is at least 2 h. The temperature is checked at (10 ± 1) min, (30 ± 1) min, 1 h ± 1 min and 2 h ± 1 min.
7.2.6 Calculate the average maximum and minimum value of the measured values from 6 measuring points.
7.2.7 The test specimen is turned off and cooled down. Repeat the test twice from 7.2.3 to 7.2.7.
7.2.8 The heating temperature of the specimen is determined as the average value of the three tests. The results are presented up to one decimal place.
7.2.9 When relevant, repeat 7.2.3 to 7.2.8 for each other potential settings of the heating mode.
7.3 Power consumption for heating
13 7.3.1 The measuring device for power consumption is connected to the test specimen.
7.3.2 Test procedure from 7.2.1 to 7.2.4 is conducted.
7.3.3 The measurement duration is at least 2 h. Power consumption of heating is calculated from starting time to (10 ± 1) min, (30 ± 1) min, 1 h ± 1 min and 2 h ± 1 min.
7.3.4 The test specimen is turned off and cooled down. Repeat the test twice.
7.3.5 The power consumption of heating is determined as the average value of the three tests. The results are expressed in whole-number units.
7.3.6 When relevant, repeat 7.3.2 to 7.3.5 for each other potential settings of the heating mode.
