DEFINITION

Classification: 34/245

MATERIAL TREATED BY ELECTROMAGNETIC ENERGY:

(under the class definition) Subject matter in which a physical substance or object is subjected to electrical power or radiation extending across the entire range of frequencies from 10[supscrpt]23[end supscrpt] cycles per second to 0 cycles per second or corresponding wavelengths from 10[supscrpt]-13[end supscrpt] cm to infinity to remove moisture from the substance or object.

(1) Note. Where the energy is not applied to the object or material, but is used for generating heat energy that is transferred to the material or object, see other subclasses of this class or other appropriate heating classes.
