BS EN 50519:2010 Assessment of workers' exposure to electric and magnetic fields of industrial induction heating equipment
BS EN 50519 is a European Standard which specifies procedures for assessment of electric, magnetic and electromagnetic fields produced by industrial and professional induction heating equipment.
It does not apply to household appliances.
Example induction heating applications:
- melting;
- zone-melting;
- heating before hot forming;
- heating by tunnel-inductor;
- hardening / coaxial transformer handheld devices;
- tube welding;
- tube annealing;
- hardening;
- soldering;
- hard-soldering /brazing;
- bonding;
- annealing;
- metal-strip and wire heating;
- tempering;
- sintering;
- shrinking.
BS EN 50519 covers the frequency range up to 30 MHz taking into account the specific characteristics of industrial and professional induction heating equipment and its usage.
BS EN 50519 may also be used for assessment regarding the requirements of
Directive 2004/40/EC [1] on the minimum health and safety requirements regarding the exposure of workers to the risks arising from physical agents (electromagnetic fields), provided that no other relevant field sources are present in close proximity. If other field sources are present, additional assessment according to EN 50499:2008 is necessary.
BS EN 50519 does not cover protective measures for people with active implants.
