This part of IEC 60519 is applicable to industrial high-frequency dielectric heating installations
for the purpose of thermal applications such as melting, drying, welding, insect extermination
and gluing of partially or non-conductive materials such as plastics, wood, rubber, textiles, glass, ceramic, paper, bamboo, foodstuffs, etc. in both normal and protective atmospheres, using for example inert gases or vacuum.
This standard relates to high-frequency dielectric heating installations with nominal frequency
in the range from 1 MHz to 300 MHz with rated useful output power greater than 50 W.
NOTE In accordance with CISPR 11, there are preferred frequencies designated by the International Telecommunication Union for use as fundamental ISM frequencies.
The voltage band according to IEC 60519-1 relates to the mains supply voltage. In some
circuits of the dielectric heating installation, the d.c., a.c. or radio-frequency voltages can have greater values (e.g. in the generator due to a built-in transformer).
