Live working - Protective clothing against the thermal hazards of an electric arc - Part 1-1: Test methods - Method 1: Determination of the arc rating (ELIM, ATPV and/or EBT) of clothing materials and of protective clothing using an open arc

IEC 61482-1-1:2019 specifies test method procedures to determine the arc rating of flame resistant clothing materials and garments or assemblies of garments intended for use in clothing for workers if there is an electric arc hazard. An open arc under controlled laboratory conditions is used to determine the values of ELIM, ATPV or EBT of materials, garments or assemblies of garments. NOTE 1 The user can, if he desires, classify the arc protective performance into arc rating protection levels based on ELIM, ATPV and/or EBT values which correspond best to the different hazard and risks levels that can result from the user’s risk analysis. NOTE 2 This document is not dedicated to classifying the arc protective performance of the material and clothing into arc protection classes. Procedures determining these arc protection classes APC1 and APC2 are specified in IEC 61482 1-2, which uses a constrained arc for testing.  NOTE 3 This test method is not intended and not appropriate to evaluate whether materials or garments are flame resistant or not, as this is covered in IEC 61482-2. Other effects than the thermal effects of an electric arc like noise, light emissions, pressure rise, hot oil, electric shock, the consequences of physical and mental shock or toxic influences are not covered by this document. Protective clothing for work intentionally using an electric arc, e.g. arc welding, plasma torch, is not covered by this document. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - addition of the Incident energy limit (ELIM) as a further arc rating performance property value; - replacement of char length requirement in the scope by indication that Procedure A is applicable for testing of materials meeting the limited flame spread requirements of IEC 61482-2; - clarification of the definition and the meaning of the Stoll curve; - modification of specification of positioning of monitor sensors with respect to the electric arc as function of intended high incident energy exposure of test specimens; - modification of specifications of monitor sensor construction; - specification of black paint; - elimination of calorimeters from the chest of the mannequin; - specification for possible positioning of mannequin(s) at a height different from the centre of the electric arc and possible turning in order to adequately expose all parts of the garment or clothing which would affect performance; - more explicit description of requirements for data acquisition system; - preconditioning of the samples; - modification of requirements for apparatus and arc exposure verification by bare shots; - more explicit description of test procedures A and B, in particular the subclauses dealing with “sequence of test”, “test parameter” and “test criteria”; - addition of determination of arc rating values of garments and/or garmet assemblies. Key words: Protective Clothing, Thermal Hazards, Open Arc, Arc Rating

Arbeiten unter Spannung - Schutzkleidung gegen thermische Gefahren eines Lichtbogens - Teil 1-1: Prüfverfahren - Verfahren 1: Bestimmung der Lichtbogen-Kennwerte (ELIM, ATPV und/oder EBT) von Bekleidungsstoffen und Schutzkleidung mithilfe eines offenen Lichtbogens

Travaux sous tension - Vêtements de protection contre les dangers thermiques d’un arc électrique - Partie 1-1: Méthodes d’essai - Méthode 1: Détermination de la valeur assignée d’arc (ELIM, ATPV et/ou EBT) des matériaux pour vêtements et des vêtements de protection utilisant un arc ouvert

IEC 61482-1-1: 2019 définit des procédures d’essai permettant de déterminer la valeur assignée d’arc des matériaux pour vêtements et des articles d’habillement ou assemblages d’articles d’habillement résistant à la flamme, destinés à être utilisés dans les vêtements pour travailleurs en cas de danger d’arc électrique. Un arc ouvert dans des conditions de laboratoire contrôlées permet de déterminer les valeurs de l’ELIM, de l’ATPV ou de l’EBT des matériaux, articles d’habillement ou assemblages d’articles d’habillement. NOTE 1 L’utilisateur peut, s’il le souhaite, classer les performances de protection d’arc en niveaux de protection des valeurs assignées d’arc sur la base des valeurs ELIM, ATPV et/ou EBT qui correspondent le mieux aux différents niveaux de danger et de risque, que l’analyse du risque par l'utilisateur peut produire. NOTE 2 Le présent document n’a pas pour objet la répartition des performances de protection d’arc des matériaux et des vêtements en classes de protection d’arc. L’IEC 61482 1-2, qui utilise un arc contraint pour les essais, spécifie des procédures de détermination de ces classes de protection d’arc APC1 et APC2. NOTE 3 Cette méthode d’essai n’est ni destinée ni appropriée à l'évaluation du caractère de résistance à la flamme ou non des matériaux ou des articles d’habillement puisque cela est couvert par l’IEC 61482-2. Le présent document ne couvre pas les effets autres que thermiques d’un arc électrique, comme le bruit, les émissions lumineuses, l’augmentation de la pression, l’huile chaude, le choc électrique, les conséquences d’un choc physique ou mental ou des effets toxiques. Le présent document ne couvre pas les vêtements de protection utilisés pour réaliser des travaux utilisant intentionnellement un arc électrique, par exemple un soudage à l’arc, une torche à plasma. Cette deuxième édition annule et remplace la première édition parue en 2009. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - ajout de la limite d’énergie incidente (ELIM – Energy Limit) comme valeur de propriété supplémentaire relative à l’application de la valeur assignée d’arc; - remplacement dans le domaine d’application de l’exigence concernant la longueur de carbonisation par une indication de l’applicabilité de la procédure A pour l'essai des matériaux satisfaisant aux exigences concernant la propagation limitée de flamme spécifiées dans l’IEC 61482-2; - clarification de la définition et de la signification de la courbe de Stoll; - modification de la spécification de placement des capteurs de surveillance par rapport à l’arc électrique en fonction de l’exposition des éprouvettes d'essai à une énergie incidente élevée; - modification des spécifications de constitution des capteurs de surveillance; - spécification de la peinture noire; - suppression des calorimètres de la poitrine du mannequin; - spécification du placement possible du ou des mannequins à une hauteur différente par rapport au centre de l’arc électrique et de la rotation possible permettant une exposition appropriée de toutes les parties de l’article d’habillement ou du vêtement qui altèrent les performances; - description plus explicite des exigences concernant le système d'acquisition de données; - préconditionnement des échantillons; - modification des exigences concernant la vérification de l’appareil et de l’exposition à l’arc par des tirs à blanc; - descr

Ta dokument določa postopke preskusnih metod za določitev zaščitnega razreda pri obloku materialov za oblačila, odporna proti plamenu, in oblačila ali sklope oblačil, namenjenih za delavce, če obstaja nevarnost električnega obloka. Odprti oblok v nadzorovanih laboratorijskih pogojih se uporablja za določanje vrednosti ELIM, ATPV ali EBT materialov, oblačil ali sklopov oblačil. Drugi učinki razen toplotnih učinkov električnega obloka, kot so hrup, emisije svetlobe, dvig tlaka, vroče olje, električni udar, posledice telesnega in duševnega šoka ali strupenih vplivov, niso zajeti v tem dokumentu. Zaščitna oblačila za opravljanje dela z načrtovano uporabo električnega obloka, npr. obločno varjenje in plazemski gorilniki, niso zajeta v tem standardu.
