Fire extinguishing media - Foam concentrates - Part 2: Specification for high 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 high 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 low and/or medium expansion foams.

Feuerlöschmittel - Schaummittel - Teil 2: Anforderungen an Schaummittel zur Erzeugung von Leichtschaum zum Aufgeben auf mit Wasser nicht mischbaren Flüssigkeiten

Diese Europäische Norm legt Anforderungen an chemische und physikalische Eigenschaften und Mindestanforderungen an die Leistungsfähigkeit von Leichtschäumen fest, die für die Aufgabe auf nicht polare (mit Wasser nicht mischbare) Flüssigkeiten geeignet sind. Anforderungen an die Kenn-zeichnung 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 überein¬stimmen und deshalb auch für die Anwendung als Schwer  und/oder Mittelschäume geeignet sein.

Agents extincteurs - Émulseurs - Partie 2 : Spécifications pour les émulseurs haut foisonnement destinés à une application à la surface des 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 haut 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 série de normes et qu’ils conviennent donc à une application comme émulseurs bas et/ou moyen foisonnement.

Gasila - Penila - 2. del: Specifikacija za penila za lahko 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 visokoekspanzijskih pen, primernih za površinsko uporabo pri tekočinah, ki se ne mešajo z vodo. Navedene so tudi zahteve za označevanje.
Tipsko odobritev morajo izvesti 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 nizko- in/ali srednjeekspanzijske pene.

Overview

EN 1568-2:2018 - issued by CEN - specifies requirements for high expansion foam concentrates intended for surface application to water-immiscible liquids (Class B fires). This European Standard defines the chemical and physical properties, minimum performance criteria, sampling and test methods, marking and the information to be supplied with the product. It is Part 2 of the EN 1568 series on fire extinguishing foam concentrates and supersedes the 2008 edition.

Important: any change in the composition of an approved product invalidates its type approval under this standard.

Key topics and technical requirements

The standard covers laboratory and performance tests that demonstrate safe and effective use of high expansion foams. Key technical topics include:

• Physical and chemical properties
  • Sediment content (before and after ageing)
  • Freezing point (new to the 2018 edition)
  • Viscosity (Newtonian and pseudo‑plastic behaviour)
  • pH and surface tension of the foam solution
• Stability and separation
  • Stability/separation test to assess concentrate integrity after storage or conditioning
• Foam performance
  • Determination of expansion and drainage time
  • Test fire performance (practical extinguishing capability on water‑immiscible fuels)
• Health and environmental considerations
  • Occupational health and ecotoxicological information and testing (introduced in 2018)
• Documentation and marking
  • Technical data sheet requirements and container marking rules
• Sampling and test methods
  • Normative annexes provide detailed procedures (sampling, viscosity, freezing point, surface tension, fire tests)

The 2018 revision also removed interfacial tension and spreading-coefficient tests and added freezing point and stability/separation requirements.

Applications

EN 1568-2:2018 is used to:

• Certify and compare high expansion foam concentrates for firefighting applications against water‑immiscible fuels (e.g., hydrocarbon spills).
• Establish procurement specifications for facilities requiring foam fire suppression (airports, chemical plants, storage tanks).
• Inform safe handling, storage and labeling requirements for foam concentrate manufacturers and suppliers.

Who should use this standard

• Foam concentrate manufacturers and formulators (product design, testing, conformity)
• Independent testing laboratories and conformity assessment bodies
• Fire protection engineers and system designers specifying high expansion foam systems
• Facility owners/operators, procurement teams and regulators evaluating foam products

Related standards

• EN 1568-1 (medium expansion foams)
• EN 1568-3 (low expansion foams for water-immiscible liquids)
• EN 1568-4 (low expansion foams for water-miscible liquids)
• Other fire extinguishing media standards referenced by CEN (e.g., powders, CO2)

Grades of foam concentrate Foam concentrate are graded as follows: a) protein foam concentrates (P): these are liquids derived from hydrolysed protein materials; b) fluoroprotein foam concentrates (FP): these are protein concentrates with added fluorinated surface active agents; c) synthetic foam concentrates (S): these are based upon mixtures of hydrocarbon surface-active agents and do not contain fluoro organic compounds; d) alcohol resistant foam concentrates (AR): these can be suitable for use on hydrocarbon fuels, and additionally are resistant
