DIN EN 61922:2003-04

The document is applicable to industrial radio- or high-frequency induction heating installations used for the purpose of thermal applications (e. g. for surface hardening, welding, soldering, melting, forging, zone refining of semiconductors, etc.). This standard relates to high-frequency induction heating installations in the frequency range up to 300 MHz for power levels of 500 W and above, comprising high-frequency generators and inductors together with necessary mechanical devices for charge handling (e. g. hardening machines).
