OAR 333-112-0040: Operation of Microwave Ovens

(1) No person shall operate or direct the operation of a microwave oven that has been determined to leak microwave radiation in excess of the following limits: (a) For ovens manufactured after October 1, 1971, leakage in excess of five milliwatts per square centimeter at any point five centimeters or more from the external surface of the oven; (b) For ovens manufactured before October 1, 1971, leakage in excess of ten milliwatts per square centimeter at any point five centimeters or more from the external surface of the oven. (2) Microwave ovens shall be considered to be in compliance with section (1) of this rule if the maximum power density of microwave radiation leakage measured in the test procedures specified in OAR 333-112-0020 does not exceed the microwave radiation leakage limits specified in section (1) of this rule measured through at least one stirrer cycle.
