MEASURING MICROWAVE POWER OUTPUT USING THE IEC-705 RATING STANDARD

When determining the microwave oven’s power output using the IEC-705 rating standard, the following conditions must be met:

•When making microwave power output mea- surements, the oven is supplied with its rated line voltage, and operated at its maxi-

mum power output setting with a load of 1000 (±5) cc of potable water.

•The water is contained in a cylindrical boro- silicate glass vessel having a maximum material thickness of 1/8" and an outside diameter of approximately 7.6".

•The oven and the empty vessel are at ambi- ent temperature prior to the start of the test.

•The initial temperature of the water is 10˚C

±2˚ (50˚F). It is measured immediately be- fore the water is added to the vessel. After addition of the water to the vessel, the load is immediately placed on the center of the shelf, which is in the lowest position, and the microwave power switched on.

•The time (in seconds) for the temperature of the water to rise by a value of 10˚C ±2˚ is measured. The initial and final water tem- peratures are selected so that the maximum difference between the final water tempera- ture, and the ambient temperature, is 5˚C.

•The microwave power output (in watts) is calculated, using the following formula:

(L) 4187 (∆T)

P =

T1

L = time (in seconds).

P = microwave output power. (∆T) = temperature rise.

•Microwave power output is measured with the oven operating at full power. The mag- netron filament heat-up time (approximately 2-seconds) is not included.

•The water is stirred to equalize the tempera- ture throughout the vessel, prior to measur- ing the final water temperature.

•Stirring devices and measuring instruments are selected to minimize the addition or removal of heat.
