The temperature rise on the surface of an electrical appliance
incorporating heating elements and at places in its vicinity is checked
by keeping the appliance in a suitable location inside a test corner.
The appliance is kept switched on till a steady state is attained, after
which the temperatures at its external surface and selected points in
its vicinity are checked and the temperature rise compared against the
specified maximum permissible values.
The Test Corner
consists of an enclosure made from 19 mm thick commercial ply-board
having a top, a bottom, and two sides joined together at right angles to
form one corner of a room. A number of equally spaced copper discs are
fitted on the roof, floor, and on each of the two walls of the test
corner. A thermocouple junction is soldered on to the back of each disc.
The discs are fixed flush with inner face of the ply-board.
