The oil temperature is measured in four corners of a rectangle inscribed within 20 mm from the edges of the
pan bottom, at the mid-height of the minimum oil level when cold.
The four temperatures are read after 3 cycles of the thermostat and it is checked that the average temperature
of the four points meets the requirement of 6.3.2.101.
The test is then continued in frying mode as follows:
The pan is filled to its minimum indicated level with oil at (20 ± 5) °C.
The oil temperature is measured at one point located at the geometric centre of the oil, 25 mm below the
surface.
After the thermostat has cut out three times in succession, it is checked that the requirement of 6.3.2.101 is
met.
7.4.2.2.102 Checking of the overheat limit device (Only for deep fat brat pans)
After each of the two tests described in 7.4.2.2.101 the thermostat is put out of action.
The maximum temperature is measured after the overheat device has operated, and it is checked that the
requirement of 6.3.2.102 is met.
