1.1 Scope and object
This International Standard is applicable to industrial radio- or high-frequency dielectric
heating installations used for the purpose of thermal applications such as heating.
assembly by melting, melting and drying of partially conductive or non-conductive ma-
terials, such as plastics, wood, rubber, textiles, glass, ceramics, paper, foodstuffs, etc., in
both normal and protective atmospheres, using, for example, inert gas or vacuum.
This standard relates to high-frequency dielectric heating installations in the frequency
range 1 MHz to 300 MHz for power levels of 50 W and above. Comprising high-frequency
generators and capacitors for the substance to be heated which, according to the require-
ments, may also contain the necessary mechanical devices.
The main purpose of this standard is to assist in compliance with the requirements set out
in 6.4 of IEC 519-9, when testing electro-heating power sources. It is not primarily
intended as a means of representing a potential high-frequency heating application for the
requirement of the user. Due to the large variety of dielectric heating applications, any
output power figures obtained as a result of these tests should not be taken as represent-
ing the amount of power that can be dissipated into a particular dielectric heating instal-
lation, but in certain instances the output power figures could be used as an indication of
performance.
The amount of power required to heat a product will be dependent, for example, on the
type of material, temperature and moisture and on the construction of the electrode
system.
This standard relates to equipment normaily operating under continuous rated conditions
and where the output terminals are easily accessible.
