What is BS EN 61922 – High-frequency induction heating installations about?
BS EN 61922 is an International Standard 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.).
BS EN 61922 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).
Loads as described in BS EN 61922 may be used in compliance assessment of electromagnetic compatibility according to CISPR 11.
Electronic systems of power measurement are commercially available, but care must be taken in their application because accuracy cannot be guaranteed, particularly at higher frequencies. These instruments require high current transformers and voltage transformers for the output power measurements, and they also are subject to errors at higher frequencies. These methods require expert knowledge for successful application and therefore are not detailed in BS EN 61922.
Who is BS EN 61922 - High-frequency induction heating installations for?
BS EN 61922 on induction heating installations is useful for:
Why should you use BS EN 61922 - High-frequency induction heating installations?
An induction through-heating installation is more complex than an induction melting furnace, as it includes more heating manners, varieties, and sizes.
The guidance in BS EN 61922 provides you with definitions, tests loads and descriptions of tests for the evaluation of the power output of the generator for induction heating installations.
The main purpose of BS EN 61922 is to provide the test methods for the determination of output power of industrial high-frequency induction heating power sources.
If you are a manufacturer of induction heating installations, compliance with BS EN 61922 testing can demonstrate whether the generator is fit for purpose and contributed to the overall performance of heating installations. As a result, you can ensure your products are safe, reliable and effective when in use.
