Microwave Leakage Limit
Microwave heating equipment shall be designed, constructed and operated to provide adequate protection against radiation hazards due to microwave leakage.
All equipment where accessibility to the applicator by a part of the human body is possible to be provided with means of access. Such means of access may be omitted if other types of protective measures such as doors or barriers are arranged with required interlocking.
On the basis of current knowledge and pending he conclusions of work under way in different countries, the microwave leakage power density shall not exceed a power density of 50 W / m2 (5 mW / cm2) at any accessible location 0.05 m from any portion of the equipment under conditions designated as "normal operations". In addition, the microwave leakage shall not exceed a power density of 100 W / m2 at any accessible location 0.05 m from any portion of the equipment under conditions designated as "abnormal operations".These levels shall not be exceeded at any point located at distances greater than 0.05 m.
