IEC 60675 pdf free download.Household electric direct-acting room heaters – Methods for measuring performance.
NOTE 2 — If the results obtained by testing the heater as specified are considered to be misleading due to the national nominal supply voltage, the heater may also be tested at a power input corresponding to the nominal voltage of the national supply system.
Adjustment:
Controls to be set by the user are set at the maximum position.
NOTE 3 — The intention is to obtain an energy ratio of 100 %. If this cannot be obtained due to the ambient temperature thermostat cycling, even at the lowest limit of the test room temperature. this thermostat is short- circuited or otherwise rendered inoperative.
Test rooms.’
The tests of clauses 7, 8, 9, 10, 14, 15 and 16 are carried out in a draught-free room in which the ambient temperature is maintained at 23 °C ± 2 °C.
The tests of clauses 11, 12 and 13 are carried out in a room where the heat losses can be adjusted. This room is referred to as a “climatic test room” and an example is given in annex A.
Positioning of the heater:
For the measurement of clauses 8, 9 and 10, the heater is placed in a corner which consists of two walls, a floor and, if necessary, a ceiling, at right angles. The corner is made of dull- black painted plywood having a thickness of approximately 20 mm.
The heater is positioned in the corner as folio ws.
— Portable fan heaters are placed with the back 150 mm from one of the walls and away from the other wall.
— Other heaters normally placed on a floor are positioned with their back as near as possible to one of the walls and away from the other wall. However, portable heaters intended to emit heat in several directions are moved away from the wall by a distance of 300 mm.
— Heaters normally fixed to a wall are fixed to one of the walls, as near to the other wall and to the floor as is likely to occur in normal use, unless otherwise stated in the instructions for installation. A dull-black painted plywood shelf having a thickness of approximately 20 mm and a depth of 200 mm is fixed over the heater as near as possible to the top of the heater unless otherwise stated in the instructions.
— Heaters normally fixed to the ceiling are fixed to the ceiling as near to the walls as is likely to occur in normal use, unless otherwise stated in the instructions for installation.
However, built-in heaters are installed according to the instructions for installation, using dull- black painted plywood approximately 20 mm thick. The heater is installed as close as possible to a similar dull-black painted floor or ceiling, unless otherwise stated in the instructions.
7 Dimensions, mass and means of connection to the supply
The overall length, height and depth of the heater, including any knobs, handles and fixing brackets, are determined.
The dimensions are stated in millimetres, rounded up to the nearest 5 mm. The mass is stated in kilograms, rounded up to the nearest 0,1 kg.
