Protective clothing - Clothing to protect against heat and flame - Minimum performance requirements (ISO/DIS 11612:2024)

ISO 11612:2015 specifies performance requirements for protective clothing made from flexible materials, which are designed to protect the wearer's body, except the hands, from heat and/or flame. For protection of the wearer's head and feet, the only items of protective clothing falling within the scope of ISO 11612:2015 are gaiters, hoods, and overboots. However, concerning hoods, requirements for visors and respiratory equipment are not given.
The performance requirements set out in ISO 11612:2015 are applicable to protective clothing which could be worn for a wide range of end uses, where there is a need for clothing with limited flame spread properties and where the user can be exposed to radiant or convective or contact heat or to molten metal splashes.

Schutzkleidung - Kleidung zum Schutz gegen Hitze und Flammen - Mindestleistungsanforderungen (ISO/DIS 11612:2024)

Dieses Dokument legt die Leistungsanforderungen an Schutzkleidung fest, die aus flexiblen Materialien besteht und zum Schutz des Körpers des Trägers, mit Ausnahme der Hände, gegen Hitze und/oder Flammen vorgesehen ist. Die einzigen Teile von Schutzkleidung zum Schutz von Kopf und Füßen des Trägers, die in den Anwendungsbereich dieses Dokuments fallen, sind Gamaschen, Hauben und Überschuhe. Für Hauben werden jedoch keine Anforderungen an Sichtscheiben und Atemgeräte angegeben.
Die in diesem Dokument angegebenen Leistungsanforderungen sind anwendbar für Schutzkleidung, die bei zahlreichen Endanwendungen getragen werden könnte, bei denen Kleidung mit begrenzter Flammenausbreitung erforderlich ist und bei denen der Träger Strahlungswärme, konvektiver Wärme oder Kontaktwärme oder Spritzern geschmolzenen Metalls ausgesetzt sein kann.
Dieses Dokument ist nicht anwendbar für Schutzkleidung, die in anderen Internationalen Normen festgelegt ist (siehe Einleitung).

Vêtements de protection - Vêtements de protection contre la chaleur et les flammes - Exigences de performance minimales (ISO/DIS 11612:2024)

L'ISO 11612:2015 spécifie les exigences de performance relatives aux vêtements de protection fabriqués avec des matériaux souples, conçus pour protéger le corps de l'utilisateur, sauf les mains, contre la chaleur et/ou les flammes. Pour la protection de la tête et des pieds, les seuls articles d'habillement de protection relevant du domaine d'application de l'ISO 11612:2015 sont les guêtres, les cagoules et les couvre-chaussures. Toutefois, en ce qui concerne les cagoules, aucune exigence n'est donnée pour les visières et les appareils respiratoires.
Les exigences de performance fournies dans l'ISO 11612:2015 sont applicables aux vêtements de protection qui pourraient être portés pour un large éventail d'utilisations finales, où il existe un besoin de vêtements offrant des propriétés de propagation de flamme limitée et où le porteur peut être exposé à une chaleur émise par rayonnement, par convection ou par contact ou à des projections/éclaboussures de métal en fusion.
