UNE-EN IEC 62822-3:2018

This Basic Standard applies to equipment for resistance welding and allied processes

designed for occupational use by professionals and for use by laymen.

NOTE 1 Typical allied processes are resistance hard and soft soldering or resistance heating achieved by means

comparable to resistance welding equipment.

This standard specifies procedures for the assessment of human exposure to magnetic fields

produced by resistance welding equipment. It covers non-thermal biological effects in the

frequency range from 0 Hz to 10 MHz and defines standardized test scenarios.

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.

This Basic Standard does not define methods for workplace assessment regarding the risks

arising from electromagnetic fields (EMF). However, the EMF data that results from the

application of this Basic Standard can be used to assist in workplace assessment.

Other standards may apply to products covered by this standard. In particular this standard

cannot be used to demonstrate electromagnetic compatibility with other equipment. It does

not specify any product safety requirements other than those specifically related to human

exposure to electromagnetic fields.

This standard focuses on the use of coupling coefficients to assess the exposure to EMF.
