Scope

This Standard specifies the minimum allowable values of energy efficiency, efficiency
grades, test methods and inspection rules for household and similar microwave ovens
(hereinafter referred to as microwave ovens).
This Standard applies to microwave ovens of maximum rated input power 2 500 W
and below, including combination microwave ovens, which heat materials and foods in
the chamber with the electromagnetic energy of ISM frequency band, 2450 MHz, and
resistive electrical heating elements.
This Standard does not apply to commercial microwave ovens, industrial microwave
ovens and microwave ovens with range hoods.
NOTE ISM frequency band is the electromagnetic frequency range which was decided by the
International Telecommunications Union (ITU) and adopted in the standard numbered CISPR
11.The standard was developed by the International Special Committee on Radio Interference
(CISPR).
