42、nd textile composition (Clause 7); evenness of temperature (Clause 8); heating-up time and energy consumption (Clause 9); stability of temperature (Clause 10); effect of laundering (Clause 11); control settings (Clause 12). 6 General conditions for measurements Unless otherwise specified, measuremen

43、ts are made under the following conditions: a) Test room: The tests are carried out in a draught-free room in which the ambient temperature is maintained at 20 C 5 C. b) Supply voltage: The supply voltage is maintained at the rated voltage 1 %. When the appliance is marked with a rated voltage range

44、, the report shall state the voltage used for the test. NOTE 1 If the results obtained by testing the appliance at rated voltage are considered to be misleading due to the national supply voltage, the appliance can also be tested at a voltage corresponding to the nominal voltage of the national supp

45、ly system. BS EN 60299:2014IEC 60299:2014 IEC 2014 9 c) Arrangement of the appliance: Any detachable cover is fitted and the flexible part is placed between sheets of thermal insulation , the size of which is such that the edges extend at least 100 mm beyond the outline of the heated area. d) The th

46、ermal insulation is made of open-cell polyether having: cell count 18 + 2 per cm; specific mass 30 kg/m3+10 %; hardness between 120 N and 170 N at 40 % impression measured according to ISO 2439. The thermal insulation is supported over its entire area by a piece of plywood 20 mm thick, situated not

47、less than 300 mm above the floor. The thickness of the thermal insulation under the appliance is approximately 72 mm and over the appliance approximately no material for duvets, 7,2 mm for overblankets and wraps, 36 mm for underblankets NOTE 2 The specification of the thermal insulation is taken fro

48、m IEC 60335-2-17:2012, Annex AA. The above specified thickness of the thermal insulation is for reference; the exact thickness shall be calibrated as specified in IEC 60335-2-17:2012, Annex AA. 7 Dimensions, mass and textile composition 7.1 Dimensions The dimensions of the flexible part of the appli

49、ance and the heated area are 7.1.1determined. The dimensions of a washable detachable cover are also determined in order to 7.1.2assess the effect of laundering. The appliance is spread out without tension on a flat surface and the length and width are measured. The average values for each dimension are calculated. The dimensions are stated in millimetres (mm), rounded to the nearest 10 mm. The lengths of flexible cords are determined. 7
