Matériels de soudage électrique - Évaluation des restrictions relatives à l'exposition humaine aux champs électromagnétiques (0 Hz à 300 GHz) - Partie 2: Matériels de soudage à l’arc

L'IEC 62822-2:2016 s'applique aux matériels de soudage à l'arc et techniques connexes conçus pour un usage professionnel et non professionnel.

Ocena električne varilske opreme glede na omejitve izpostavljenosti delavcev elektromagnetnim poljem (0Hz . 300 GHz) - 2. del: Osnovni standard za obločno varjenje (IEC 62822-2:2016)

Ta del standarda IEC 62822 se uporablja za opremo za obločno varjenje in sorodne postopke, zasnovano za uporabo pri delu strokovnjakov in laikov.
OPOMBA 1: Tipični sorodni postopki so električno obločno rezanje in brizganje.
Ta standard določa postopke za oceno izpostavljenosti delavcev magnetnim poljem, ki ustvarijo pri obločnem varjenju. Obravnava atermične biološke vplive v frekvenčnem razponu od 0 HZ do 10 MHz in določa standardizirane preskusne scenarije.
OPOMBA 2: Splošni izraz »polje« se v tem dokumentu uporablja za »magnetno polje«.
OPOMBA 3: Za oceno izpostavljenosti električnim poljem in toplotnim vplivom se uporabljajo metode, podane v splošnem standardu IEC 62311.
Ta standard ne določa metod za oceno delovnega mesta v povezavi s tveganji zaradi elektromagnetnih polj (EMF). Vendar podatki o elektromagnetnih poljih, ki se pridobijo na podlagi uporabe tega standarda, se lahko uporabijo kot pomoč pri ocenjevanju delovnega mesta.
Za proizvode, ki jih obravnava ta standard, se lahko uporabljajo drugi standardi. Ta standard se ne uporablja za dokazovanje elektromagnetne združljivosti z drugo opremo. Ne določa nobenih varnostnih zahtev za proizvode, razen tistih, ki se posebej navezujejo na izpostavljenost delavcev elektromagnetnim poljem.
