Fire extinguishing media - Foam concentrates - Part 4: Specification for low expansion foam concentrates for surface application to water-miscible liquids
This document specifies requirements for chemical and physical properties, and minimum performance requirements of low expansion foams suitable for surface application to water-miscible liquids. Requirements are also given for marking.
IMPORTANT — In this part of the document, the fire performance is tested using acetone and isopropanol as the fuel, which also forms the basis for the performance classification. However, there are a large number of water-miscible liquids, which have more or less different properties to acetone and isopropanol. It has been shown by tests using other fuels that the performance of various foams can differ considerably. Examples of such fuel is Methyl Ethyl Ketone (MEK). It is therefore essential that the user checks for any unfavourable or unacceptable loss of efficiency when the foam is used against fires in any other water-miscible fuels than acetone and isopropanol resepectively. The fire test conditions and procedure given in J.2 can be used in order to achieve results comparative with acetone and isopropanol resepectively and related requirements.
It is also essential for the user to note, that other fuel depths and methods of application than those specified in I.2, can cause considerable loss of efficiency and these matters should be carefully considered by the user when assessing the suitability for particular applications.
NOTE Some concentrates conforming to this part of EN 1568 can also conforms to other parts and therefore can also be suitable for application as medium and/or high expansion foams.
Feuerlöschmittel - Schaummittel - Teil 4: Anforderungen an Schaummittel zur Erzeugung von Schwerschaum zum Aufgeben auf polare (mit Wasser mischbare) Flüssigkeiten
Dieses Dokument legt Anforderungen an chemische und physikalische Eigenschaften und Mindestanforderungen
an die Leistungsfähigkeit von Schwerschäumen fest, die für die Aufgabe auf mit Wasser
mischbare, brennbare Flüssigkeiten geeignet sind. Anforderungen an die Kennzeichnung sind ebenfalls
festgelegt.
WICHTIG - In diesem Teil der Europäischen Norm wird die Löschwirksamkeit mit Aceton und
Isopropanol als Brennstoffe geprüft, die ebenfalls auch als Grundlage für die Einteilung in
Löschleistungsstufen verwendet werden. Es gibt jedoch eine große Anzahl von wassermischbaren
(polaren) Flüssigkeiten, die gegenüber Azeton bzw. Isopropanol mehr oder weniger unterschiedliche
Eigenschaften aufweisen. Es wurde bei Prüfungen unter Verwendung anderer Brennstoffe
nachgewiesen, dass verschiedene Schaummittel in ihrer Löschleistung beträchtlich abweichen
können. Beispiel für einen solchen Brennstoff ist Methyl-Ethyl-Keton (MEK). Es ist daher von
Bedeutung, dass der Anwender beim Einsatz von Schaum gegen Brände mit jedem anderen
wassermischbaren (polaren) Brennstoff als Azeton bzw. Isopropanol diese auf unvorteilhaften oder
unannehmbaren Wirksamkeitsverlust überprüft. Es können die in J.2 angegebenen Bedingungen und
Verfahren der Brandprüfung angewendet werden, um Ergebnisse zu erreichen, die mit Azeton bzw.
Isopropanol und zugehörigen Anforderungen vergleichbar sind.
Es ist für den Anwender auch von Bedeutung, dass er beachtet, dass andere, von I.2 abweichende,
Brennstofftiefen und Aufgabeverfahren einen beträchtlichen Wirkungsverlust verursachen können, und diese
Faktoren sollten vom Anwender sorgfältig beachtet werden, wenn er die Eignung für eine besondere Aufgabe
bewertet.
ANMERKUNG Einige diesem Teil von EN 1568 entsprechende Schaummittel können auch mit den anderen Teilen
übereinstimmen und deshalb für die Anwendung als Mittel- und/oder Leichtschäume geeignet sein.
Agents extincteurs - Emulseurs - Partie 4: Spécifications pour les émulseurs bas foisonnement destinés à une application à la surface de liquides ayant une affinité pour l'eau
La présente Norme européenne spécifie les prescriptions en matière de propriétés chimiques, physiques et de performances minimales des émulseurs bas foisonnement convenant à une application à la surface des liquides ayant une affinité pour l'eau. Des prescriptions concernant les marquages sont également fournies.
IMPORTANT — Dans cette partie de la norme européenne, les performances au feu sont contrôlées en utilisant de l'acétone comme combustible, ce qui constitue également la base de la classification des performances. Il existe toutefois un grand nombre de liquide ayant une affinité avec l'eau dont les propriétés sont plus ou moins différentes de celles de l'acétone. Des essais effectués avec d'autres combustibles ont également permis de démontrer que les performances des diverses mousses pouvaient varier de façon considérable. L'alcool isopropylique et la méthyléthylcétone (MEK) sont des exemples de ces combustibles. Il est donc essentiel que l'utilisateur vérifie que la mousse ne présente pas une perte d'efficacité défavorable ou inacceptable lorsqu'elle est employée pour des feux impliquant des combustibles autres que l'acétone ayant une affinité avec l'eau. Les conditions d'essai au feu et le mode opératoire donnés en J.2 peuvent être utilisés pour obtenir des résultats comparatifs avec l'acétone et les prescriptions correspondantes. D'autres combustibles peuvent également nécessiter l'utilisation d'autres taux d'application, supérieurs ou inférieurs, afin d'obtenir des données d'essais correctes. D'autres bacs à feu pourraient alors être utilisés mais la quantité de combustible devrait être modifiée afin d'obtenir la même hauteur de combustible comme spécifié en J.2.
Gasila - Penila - 4. del: Specifikacija za penila za težko peno za površinsko uporabo pri tekočinah, topnih v vodi
Ta dokument določa zahteve za kemične in fizične lastnosti in minimalne zahteve za zmogljivost težkih pen, primernih za površinsko uporabo pri tekočinah, topnih v vodi. Podane so tudi zahteve za označevanje. Prav tako je za uporabnika pomembno, da upošteva, da lahko druge intenzivnosti goriv, ki niso določene v točki I.2, povzročijo znatno zmanjšanje učinkovitosti. Uporabnik mora te zadeve pozorno upoštevati, ko presoja o primernosti posameznih naprav.
