Measurement Procedure.)
Note: The door on a microwave oven is designed to act
as an electronic seal preventing the leakage of
microwave energy from oven cavity during cook
cycle. This function does not require that door be
air-tight, moisture (condensation)-tight or light-
tight. Therefore, occasional appearance of
moisture, light or sensing of gentle warm air
movement around oven door is not abnormal and
do not of themselves indicate a leakage of
microwave energy from oven cavity.
