Live working - Protective clothing against the thermal hazards of an electric arc - Part 1-1: Test methods - Method 1: Determination of the arc rating (ATPV or EBT50) of flame resistant materials for clothing

IEC 61482-1-1:2009 specifies test methods to measure the arc thermal performance value of materials intended for use in heat- and flame-resistant clothing for workers exposed to the thermal effects of electric arcs and the function of garments using these materials. These test methods measure the arc thermal performance value of materials which meet the following requirements: less than 100 mm char length and less than 2 s afterflame after removal from flame, when tested in accordance with ISO 15025, procedure B (bottom-edge ignition) on the outer material, and the char length measured using a modified ISO method as described in Annex A. These methods are used to measure and describe the properties of materials, products, assemblies or garments, in response to convective and radiant energy generated by an electric arc in open air under controlled laboratory conditions. The materials used in these methods are in the form of flat specimens for method A and garments for method B. Method A is used to determine the arc rating of materials and material assemblies when tested in a flat configuration. Method B is used to measure garment response, not arc rating, to an arc exposure including all the garment findings, sewing thread, fastenings, fabrics and other accessories when tested on a male mannequin torso. Method B is also used for accident replication.

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 caractéristique d'arc (ATPV ou EBT50) de matériaux résistant à la flamme pour vêtements

La CEI 61482-1-1:2009 spécifie les méthodes d'essai pour mesurer la valeur de performance thermique d'arc des matériaux destinés à être utilisés pour les vêtements résistant à la chaleur et à la flamme, pour les travailleurs exposés aux arcs électriques, ainsi que le rôle des vêtements utilisant ces matériaux. Ces méthodes d'essai mesurent la valeur de performance thermique d'arc des matériaux qui répondent aux exigences suivantes: longueur de carbonisation inférieure à 100 mm et durée de combustion inférieure à 2 s après le retrait de la flamme lors de l'essai du matériel de dessus, selon la méthode B (allumage par le bord inférieur) de l'ISO 15025, et la longueur de carbonisation mesurée selon une méthode ISO modifiée décrite à l'Annexe A. Ces méthodes sont utilisées pour mesurer et décrire les propriétés des matériaux, des produits et des assemblages ou des articles d'habillement, en réponse à l'énergie de convection et à l'énergie rayonnante générées par un arc électrique à l'air libre dans des conditions contrôlées de laboratoire. Les matériaux utilisés dans ces méthodes ont la forme d'éprouvettes plates pour la méthode A et d'articles d'habillement pour la méthode B. La méthode A est utilisée pour déterminer la caractéristique d'arc de matériaux et d'assemblages de matériaux lors de l'essai en une configuration plane. La méthode B est utilisée pour mesurer une réponse d'un article d'habillement, et non la caractéristique d'arc, à une exposition à l'arc, y compris toutes les fournitures de confection, le fil de couture, les fermetures, les tissus et les autres accessoires lors d'un essai sur un torse de mannequin mâle. La méthode B est aussi utilisée à des fins de reconstitution d'un accident.
