3 DefInitions
For the purposes of this International Standard the following definitions apply.
storage heater
heater wttich Stores heat obtained from electric energy by charging an accumulating core before a heat demand in a room occurs, the heat being discharged at any time
3.2
minimum discharge condition
condition under which the appliance is operated, the means lot controlling the heat output. such as flaps and fans, bein9 set at the lowest position
3.3
maximum discharge condition
condition under which the appliance is operated, the means for controlling the heat output. such as flaps and fans, being set at the highest position, any boost position being ignored

3.4
average room temperature
arithmetic average of the maximum and minimum room temperatures for a setting of the ambient temperature thermostat
3.5
ambient temperature thermostat
thermostat, sensitive to the room temperature and adjustable by the user, with at least the sensing part incorporated in the heater
3.8
amplitude
difference between the maximum and the minimum room temperatures for a setting of the ambient temperature thermostat
3.7
drift
difference between the average room temperatures obtained at different charge levels for a setting of the ambient temperature thermoslat
4 Classification
4.1 According to typo
a storage heater without a direct-acting heating function;
b) storage heater with a direct-acting function manually controlled;
C) storage heater with a direci-acting function automatically controlled.
4.2 According to the control of heat output a) storage heater without heat output control;
b) storage heater with the heat output controlled by flaps or similar means; c) storage heater with the heat output controlled by a fan.
5 LIst of measurements
a) dimensions and mass (clause 7);
b) charge acceptance (clause 8):
c) room heating capability (clause 9);
d) heat retention (clause 10);
e) temperature rises of air-outlet grilles and external surlaces (clause 11):
I) temperature rises of surfaces surrounding the heater (clause 12);
g) stability of room temperature (clause 13);
h) direct-acting heating function (clause 14).
The results 01 these measurements may be given in a test report.

6 General conditions for measurements
Before carrying out the tests, the storage heater is assembled and installed in accordance with the instructions.
Unless otherwise specified, measurements ae made under the following conditions.
6.1 Supply voltage
The storage heater Is supplied at a voltage which gives rated power input under steady conditions. However, tans are supplied at rated voltage.
NOTE — Steady conditions mat not be estabhghed until the end ot lbs charging period.
Supply voltages are kept within ±1 %.
6.2 Test rooms
All tests except those of clauses 9 and 10 are carried out in a draught-free room in which the ambient temperature is maintained at 20 C ± I C. measured at a distance of approximately 2 m from the appliance and 1.5 m above the floor.
