Electric welding equipment - Assessment of restrictions related to human exposure to electromagnetic fields (0 Hz to 300 GHz) - Part 3: Resistance welding equipment
IEC 62822-3:2017 applies to equipment for resistance welding and allied processes designed for occupational use by professionals and for use by laymen. This document 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.
Einrichtungen zum Widerstandsschweißen - Bewertung elektrischer Schweißeinrichtungen in Bezug auf Begrenzungen der Exposition von Personen gegenüber elektromagnetischen Feldern (0 Hz - 300 GHz) - Teil 3: Grundnorm für Widerstandsschweißeinrichtungen
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 62822-3:2017 s'applique aux matériels de soudage par résistance et techniques connexes conçus pour un usage professionnel et non professionnel. Le présent document spécifie les procédures d'évaluation de l'exposition humaine aux champs magnétiques générés par les matériels de soudage par résistance. Il couvre les effets biologiques non thermiques dans la plage de fréquences comprises entre 0 Hz et 10 MHz et définit des scénarios d'essai normalisés.
Električna varilna oprema - Ocenjevanje omejitev z vidika izpostavljenosti človeka elektromagnetnim poljem (od 0 Hz do 300 Hz) - 3. del: Oprema za uporovno varjenje (IEC 62822-3:2017)
Ta del standarda IEC 62822 se uporablja za opremo za uporovno varjenje in sorodne postopke, zasnovano za uporabo pri delu strokovnjakov in laikov.
OPOMBA 1: Običajni povezani procesi so uporovno trdo ali mehko spajkanje ali uporovno gretje, ki se doseže na način, primerljiv z opremo za uporovno varjenje.
Ta dokument določa postopke za oceno izpostavljenosti delavcev magnetnim poljem, ki jih ustvari oprema za uporovno varjenje. 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 ali zadevnih osnovnih standardih.
Ta dokument ne določa metod za oceno delovnega mesta v povezavi s tveganji zaradi elektromagnetnih polj (EMF). Vendar se podatki o elektromagnetnih poljih, ki se pridobijo na podlagi uporabe tega osnovnega standarda, lahko uporabijo kot pomoč pri ocenjevanju delovnega mesta.
Za proizvode, ki jih obravnava ta dokument, se lahko uporabljajo drugi standardi. Tega dokumenta zlasti ni mogoče uporabljati 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.
Ta dokument se osredotoča na uporabo koeficientov spajanja za ocenjevanje izpostavljenosti elektromagnetnim poljem.
