Fire extinguishing media - Foam concentrates - Part 3: Specification for low expansion foam concentrates for surface application to water-immiscible liquids

This European Standard specifies requirements for chemical and physical properties, and minimum performance requirements of low expansion foams suitable for surface application to water-immiscible liquids. Requirements are also given for marking.
WARNING - Any type approval according to this standard is invalidated by any change in composition of the approved product.
Some concentrates conforming to this part of EN 1568 can also conform to other parts and therefore can also be suitable for application as medium and/or high expansion foams, and for application at low expansion to water-miscible liquids.

Feuerlöschmittel - Schaummittel - Teil 3: Anforderungen an Schaummittel zur Erzeugung von Schwerschaum zum Aufgeben auf mit Wasser nicht mischbare Flüssigkeiten

Diese Europäische Norm legt Anforderungen an chemische und physikalische Eigenschaften und Mindestanforderungen an die Leistungsfähigkeit von Schwerschäumen fest, die für die Oberflächenanwendung bei mit Wasser nicht mischbaren Flüssigkeiten geeignet sind. Anforderungen an die Kennzeichnung sind ebenfalls festgelegt.
WARNUNG - JEDER TYP-PRÜFBESCHEID NACH DIESER NORM WIRD BEI ÄNDERUNG DER ZUSAMMENSETZUNG DES GEPRÜFTEN PRODUKTES UNGÜLTIG.
Einige diesem Teil von EN 1568 entsprechende Schaummittel können auch mit den anderen Teilen übereinstimmen und deshalb auch für die Anwendung als Leicht  und/oder Mittelschäume sowie als Schwerschäume zur Anwendung bei wassermischbaren Flüssigkeiten, geeignet sein.

Agents extincteurs - Émulseurs - Partie 3 : Spécifications pour les émulseurs bas foisonnement destinés à une application à la surface de liquides n’ayant pas d’affinité pour l’eau

La présente Norme européenne spécifie les exigences en matière de propriétés chimiques, physiques et de performances minimales des émulseurs bas foisonnement convenant à une application à la surface de liquides n’ayant pas d’affinité pour l’eau. Des exigences concernant les marquages sont également fournies.
AVERTISSEMENT - Toute homologation de type conforme à la présente norme est invalidée dès lors qu’une modification est apportée à la composition du produit homologué.
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 qu’ils conviennent donc à une application comme émulseurs moyen et/ou haut foisonnement ainsi qu’à une application comme émulseurs bas foisonnement pour des liquides ayant une affinité pour l’eau.

Gasila - Penila - 3. del: Specifikacija za penila za težko peno za površinsko uporabo pri tekočinah, netopnih v vodi

V tem osnutku evropskega standarda so določene zahteve glede kemijskih in fizikalnih lastnosti ter minimalne zahteve glede delovanja nizkoekspanzijskih pen, primernih za površinsko uporabo pri tekočinah, ki se ne mešajo z vodo. Navedene so tudi zahteve za označevanje.
Tipsko odobritev bodo izvedli neodvisni laboratoriji tretjih oseb, ki so akreditirani v skladu s standardom EN ISO/IEC 17025.
OPOZORILO: Vsakršna tipska odobritev v skladu s tem standardom je neveljavna, če pride do kakršne koli spremembe v sestavi odobrenega izdelka.
OPOMBA Nekateri koncentrati, ki so skladni s tem delom standarda EN 1568, so lahko skladni tudi z drugimi deli in so zato lahko primerni za uporabo kot srednje- in/ali visokoekspanzijske pene ter za uporabo pri nizki ekspanziji pri tekočinah, ki se mešajo z vodo.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2018, and conflicting national standards shall be withdrawn at the latest by December 2019. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1568-3:2008. In comparison with the previous edition, the following significant changes have been made: — Interfacial tension and spreading coefficient test removed; — Freezing point test introduced; — Stability/Separation test of foam concentrate introduced; — Occupational health and ecotoxicological testing introduced; — Example of technical data sheet included; — New test procedures introduced for the Evaluation of film formation of the foam Concentrate. — Setting-up procedures of foam nozzle for the determination of expansion and drainage times have been modified in the light of ISO 7203. This document is Part 3 of EN 1568 which has the general title Fire extinguishing media — Foam concentrates. The other parts are: — Part 1: Specification for medium expansion foam concentrates for surface application to water-immiscible liquids; — Part 2: Specification for high expansion foam concentrates for surface application to water-immiscible liquids; — Part 4: Specification for low expansion foam concentrates for surface application to water-miscible liquids. This European Standard is one of a series of standards specifying requirements for fire extinguishing media in common use. This series includes the following standards: — EN ISO 5923, Equipment for fire protection and fire fighting — Fire extinguishing media — Carbon dioxide); — EN 27201-1, Fire protection — Fire extinguishing media — Halogenated hydrocarbons — Part 1: Specifications for halon 1211 and halon 1301 (ISO 7201-1); SIST EN 1568-3:2018

According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 1568-3:2018

EN 1568-3:2018 (E) 7 Introduction As fire fighting foams are chemical agents or chemical preparations Commission Directive 2000/60/CE and Regulations (EC) No 1272/2008 (CLP) and No 1907/2006 (REACH) apply and should be taken into account. Classes of fire are defined in EN 2 as follows: — Class A: fires involving solid materials, usually of an organic nature, in which combustion normally takes place with the formation of glowing embers; — Class B: fires involving liquids or liquefiable solids; — Class C: fires involving gases; — Class D: fires involving metals; — Class F: fires involving cooking media (vegetable or animal oils and fats) in cooking appliances. Fire-fighting foams are widely used to control and extinguish Class B fires and to inhibit re-ignition. These foams can also be used for prevention of ignition of flammable liquids and, in certain conditions, to extinguish Class A fires. Foams can be used in combination with other extinguishing media, particularly gaseous media and powders, which are the subject of other European Standards (see European foreword). These specifications have been designed to ensure that fire extinguishing media have the minimum useful fire fighting capability. The user should ensure that the foam concentrates are used accurately at the concentration recommended by the manufacturer. Fire performances indicated by this standard cannot replicate practical fire situations. Foam concentrates of different types and manufacture should not be mixed. It should be noted that some combinations of extinguishing powder and foam can lead to unacceptable loss of efficiency, caused by unfavourable interaction of the chosen media when applied simultaneously or successively to the fire. It is extremely important that the foam concentrate after dilution with water to the recommended concentration should not in normal usage present a significant toxic hazard to life in relation to the environment. The current version of Commission Directive 2000/60/CE, Regulations (EC) No 1272/2008 (CLP) and No 1907/2006 (REACH) apply when considering the testing of ecotoxicological properties and safety in the work environment. A special quality characteristic is the type test conducted by an independent testing laboratory accredited to EN ISO/IEC 17025. SIST EN 1568-3:2018

EN 1568-3:2018 (E) 8 1 Scope This European Standard specifies requirements for chemical and physical properties, and minimum performance requirements of low expansion foams suitable for surface application to water-immiscible liquids. Requirements are also given for marking. WARNING — Any type approval according to this standard is invalidated by any change in composition of the approved product. Some concentrates conforming to this part of EN 1568 can also conform to other parts and therefore can also be suitable for application as medium and/or high expansion foams, and for application at low expansion to water-miscible liquids. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
