2.GENERAL CONDITIONS FOR TESTING WATER HEATERS

(a)Measurements shall be carried out using the load profiles set out in Table 1;

(b)measurements shall be carried out using a 24-hour measurement cycle as follows:

00:00 to 06:59: no water draw-off,
from 07:00: water draw-offs according to the declared load profile,
from end of last water draw-off until 24:00: no water draw-off;

(c)the declared load profile shall be the maximum load profile or the load profile one below the maximum load profile;

(d)any heat generator designed for a water heater, and any water heater housing to be equipped with such a heat generator, shall be tested with an appropriate water heater housing and heat generator, respectively;

(e)water heaters to be classified as off-peak water heaters are energised for a maximum period of 8 consecutive hours between 22:00 and 07:00 of the 24-hour tapping pattern. At the end of the 24-hour tapping pattern the water heaters are energised till the end of the step.
