2-2. Judgement
The value of resistance should be applied to the value
specified below.
3. Microwave Leakage Test
3-1. Warning
1) DO NOT place your hands into any suspected
microwave leakage field unless the safe density level is
known.
2) Always start measuring of an unknown field to assure
safety for operating personnel from microwave energy.
3) Slowly approach the unit under test until the radiometer
reads and appreciable leakage from the unit under test.
4) Care should be taken not to place the eyes in direct line
with the source of microwave energy.
3-2. Method
The power density of the microwave leakage emitted by the
microwave oven should not exceed 1mW/cm
2
at any point
50mm (2 in). or more away from the external surface of the
oven as measured prior to acquisition by a purchaser and
there after once the oven is in use, 4mW/cm
2
at any point
50mm (2 in) or more away from the external surface of the
oven, checks to be made around the whole of the door seal
and on each of the main unit surface.
Measurements should be made with the oven operating at
its maximum output and containing a load of 275 ±15
milliliters of tap water initially at 68±9 ˚F (20±5 ˚C) placed
within the cavity at he center of the load carrying surface
provided by the manufacture. The water container should
be a low from 600 milli-liters beaker having an inside
diameter of approximately 85mm (3-11/32 in.) and made of
an electrically nonconductive material such as glass or
plastic.
3-3. Procedures
1) Prepare 600cc glass or plastic container.
2) Pour 275±15 milliliters of tap water initially at 68±9˚F
(20±5˚C) in the container.
3) Place it at the center of the tray and set it is a cavity.
4) Operate oven.
5) Measure the microwave leakage using a Narda 8100 or
similarly approved microwave leakage meter after a few
minutes operation.
