Safety in electroheat installations - Part 9: Particular requirements for high-frequency dielectric heating installations HD 491.9 S1:1991

Scope

This standard is applicable to industrial high-frequency heating installations for the purpose of thermal applications such as assembly by melting melting and drying of partially or non-conductive materials such as plastics, wood, rubber, textiles, glass, ceramics, paper, foodstuffs, etc, in both normal and protective atmpospheres, using for example inert gases or a vacuum * This standard is to be read in conjunction with IEC Publication 519-1: Safety in Electroheat Installations, Part 1:General Requirements * This standard related to high-frequency dielectric heating installations, in the range 1 MHz to 300 MHz with output power greater than 50 W comprising high-frequency generators and capacitors for the charge to be heated which, according to the requirements, may also contain the necessary mechanical devices (In accordance with CISPR Publication 11: Limits and methods of measurement of radio interference characteristics of industrial, scientific and medical (ISM Radio-frequency equipment (excluding surgical diathermy apparatus) there are preferred frequencies for industrial scientific and medical purposes * If other international or national regulations apply, they shall also be met CISPR Publications also give guidance regarding radio-interference suppression
