CONTAINER TEST
TO TEST A CONTAINER FOR SAFE MICROWAVE OVEN USE: Fill a microwave safe cup with cool
water and place it in the microwave oven alongside the empty container to be tested; heat one (1)
minute at P10 (HIGH). If the container is microwave oven safe (transparent to microwave energy), the
empty container should remain comfortably cool and the water should be hot. If the container is hot, it
has absorbed some microwave energy and should NOT be used. This test cannot be used for plastic
containers.
