Performance Standards for Microwave Ovens
Authors not listed
The standard sets a microwave leakage limit of 1 milliwatt per square centimeter at 5 centimeters from the oven surface before sale and 5 milliwatts per square centimeter thereafter.
Plain English Summary
The standard applies to microwave ovens manufactured after October 6, 1971 that operate at frequencies from 890 megahertz to 6,000 megahertz. It requires two safety interlocks, one concealed, and mandates that failure of any single component cannot disable all interlocks. Compliance is tested with the oven at maximum output heating 735 milliliters of tap water at 20° ± 5 centigrade. Manufacturers must provide service instructions with warnings about microwave radiation exposure.
Why This Matters
The test instrument must reach 90 percent of its steady-state reading within 3 seconds and have a detector aperture of 25 square centimeters or less with no dimension exceeding 10 centimeters. Leakage is measured through at least one stirrer cycle at the location of greatest microwave leakage. Measurements are taken with the door fully closed and with the door fixed in any other position that allows the oven to operate. A concealed interlock must not be operable by any body part or a rod 3 millimeters or greater in diameter and 10 centimeters long.
Exposure Information
Specific exposure levels were not quantified in this study. Duration: null
