Fire extinguishing media - Foam concentrates - Part 1: Specification for medium expansion foam concentrates for surface application to water-immiscible liquids
This document specifies requirements for chemical and physical properties, and minimum performance requirements of medium expansion foams suitable for surface application to water-immiscible liquids. Requirements are also given for marking.
NOTE Some concentrates conforming to this part of EN 1568 can also conform to other parts and therefore can also be suitable for application as low and/or high expansion foams.
Feuerlöschmittel - Schaummittel - Teil 1: Anforderungen an Schaummittel zur Erzeugung von Mittelschaum zum Aufgeben auf nicht-polare (mit Wasser nicht mischbare) Flüssigkeiten
Dieses Dokument legt Anforderungen an chemische und physikalische Eigenschaften und Mindestanforderungen
an die Leistungsfähigkeit von Mittelschäumen fest, die für die Aufgabe auf nicht-polare (mit
Wasser nicht mischbare) Flüssigkeiten geeignet sind. Anforderungen an die Kennzeichnung sind ebenfalls
festgelegt.
ANMERKUNG Einige diesem Teil von EN 1568 entsprechende Schaummittel können auch mit den anderen Teilen
übereinstimmen und deshalb auch für die Anwendung als Schwer- und/oder Leichtschäume geeignet sein.
Agents extincteurs - Emulseurs - Partie 1: Spécifications pour les émulseurs moyen foisonnement destinés à une application à la surface de liquides n'ayant pas d'affinité pour l'eau
La présente Norme européenne spécifie les prescriptions en matière de propriétés chimiques, physiques et de performances minimales des émulseurs moyen foisonnement convenant à une application à la surface des liquides n'ayant pas d'affinité pour l'eau. Des prescriptions concernant les marquages sont également fournies.
NOTE Il se peut que certains émulseurs conformes à la présente partie de l'EN 1568 soient également conformes à d'autres parties de cette même norme et conviennent donc à une application comme émulseurs bas et/ou haut foisonnement.
