Electric welding equipment - Assessment of restrictions related to human exposure to electromagnetic fields (0 Hz to 300 GHz) - Part 3: Resistance welding equipment
IEC 62822-3:2023 applies to equipment for resistance welding and allied processes designed for occupational use by professionals and for use by laymen. More generally, this document covers equipment for which the welding current flows in an electrical circuit whose geometry cannot be changed and regardless of the technology of the current generator (for example LF-AC, MF-DC for spot or seam welding or capacitive discharge used for stud welding). This second edition cancels and replaces the first edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) inclusion of the uncertainties in the results of the assessment; b) simplification of the methods of exposure assessment.

Matériels de soudage électrique - Évaluation des restrictions relatives à l'exposition humaine aux champs électromagnétiques (0 Hz à 300 GHz) - Partie 3: Matériels de soudage par résistance
L'IEC 62822-3:2023 s'applique aux matériels de soudage par résistance et techniques connexes conçus pour un usage professionnel et non professionnel. Plus généralement, le présent document traite des matériels où le courant de soudage circule dans un circuit électrique dont la géométrie ne peut pas être modifiée, quelle que soit la technologie du générateur de courant (par exemple LF-AC, MF-DC pour le soudage par points ou continu, ou le soudage par décharge capacitive utilisé pour le soudage de goujons). Cette deuxième édition annule et remplace la première édition parue en 2017. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) inclusion des incertitudes dans les résultats de l'évaluation; b) simplification des méthodes d'évaluation de l'exposition.
Električna varilna oprema - Ocenjevanje omejitev z vidika izpostavljenosti ljudi elektromagnetnim poljem (od 0 Hz do 300 Hz) - 3. del: Oprema za uporovno varjenje (IEC 62822-3:2023)
Standard IEC 62822-3:2023 se uporablja za opremo za uporovno varjenje in sorodne postopke, zasnovano za uporabo pri delu strokovnjakov in laikov.
Na splošno ta dokument obravnava opremo, pri kateri varilni tok teče v električnem tokokrogu, katerega geometrije ni mogoče spremeniti ne glede na tehnologijo generatorja toka (na primer LF-AC, MF-DC za točkovno ali kolutno varjenje ali kapacitivni odvod, ki se uporablja za varjenje čepov).
Druga izdaja razveljavlja in nadomešča prvo izdajo, objavljeno leta 2017. Ta izdaja je tehnično popravljena izdaja.
Ta izdaja v primerjavi s prejšnjo vključuje naslednje pomembne tehnične spremembe:
a) vključuje negotovosti v rezultate ocenjevana;
b) poenostavlja metode ocenjevanja izpostavljenosti.
