(Main)Fire extinguishing media - Foam concentrates - Part 2: Specification for high expansion foam concentrates for surface application to water-immiscible liquids
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.

European foreword
This document (prEN 1568-2:2025) has been prepared by Technical Committee CEN/TC 191 “Fixed
firefighting systems”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1568-2:2018.
This document includes the following significant technical changes with respect to EN 1568-2:2018:
— Determination of solid deposits for synthetic foams and protein foams clarified;
— Optional annual foam quality check introduced;
— Temperature and wind speed measurements for performance fire test clarified;
— Some test procedures clarified.
This document is Part 2 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 3: Specification for low 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 document 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);
— EN 27201-2, Fire protection — Fire extinguishing media — Halogenated hydrocarbons — Part 2: Code
of practice for safe handling and transfer procedures (ISO 7201-2);
— EN 615, Fire protection — Fire extinguishing media — Specifications for powders (other than class D
powders).
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 manufacturers 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.
1 Scope
This document 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.
NOTE Some concentrates conforming to this document can also conform to other parts and therefore can also
be suitable for application as low and/or medium expansion
