BS EN IEC 62822-3 applies to equipment for resistance welding and allied processes designed for occupational use by professionals and for use by laymen.
BS EN IEC 62822-3 specifies procedures for the assessment of human exposure to magnetic fields produced by resistance welding equipment.
BS EN IEC 62822-3 covers non-thermal biological effects in the frequency range from 0 Hz to 10 MHz and defines standardized test scenarios.
NOTE 1 Typical allied processes are resistance hard and soft soldering or resistance heating achieved by means comparable to resistance welding equipment.
NOTE 2 The general term "field" is used throughout this document for "magnetic field".
NOTE 3 For the assessment of exposure to electric fields and thermal effects, the methods specified in the Generic Standard IEC 62311 or relevant basic standards apply.
BS EN IEC 62822-3 on electric resistance welding equipment is useful for:
BS EN IEC 62822-3 helps the users with the guidelines for the assessment of restrictions related to human exposure to electromagnetic fields (0 Hz to 300 Hz).
BS EN IEC 62822-3 specifies the occupational use for professionals for equipment like resistance welding, arc welding, and allied processes.
BS EN IEC 62822-3 provides guidance on the use of coupling coefficients to assess the exposure to EMF.
