EN 1568-2:2018 (E) 6 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 1568-2:2018
EN 1568-2:2018 (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: a) Class A: fires involving solid materials, usually of an organic nature, in which combustion normally takes place with the formation of glowing embers; b) Class B: fires involving liquids or liquefiable solids; c) Class C: fires involving gases; d) Class D: fires involving metals; e) 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. SIST EN 1568-2:2018
EN 1568-2:2018 (E) 8 1 Scope 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.

European foreword
This document (prEN 1568-2:2016) 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 1568-2:2008.
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 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 (ISO 5923);
— EN 27201-1, Fire protection — Fire extinguishing media - Halogenated hydrocarbons —
Part 1: Specifications for halon 1211 and halon 1301 (ISO 7201-1:1989);

Introduction
As fire fighting foams are chemical agents or chemical preparations Commission
Directive 2006/60/CE and Regulations (EC) No 1272/2008 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 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 2006/60/CE,
Regulations (EC) No 1272/2008 and No 1907/2006 apply when considering the testing of
ecotoxicological properties and safety in the work environment.

1 Scope
This draft 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.
Type approval needs to be executed by independent third party laboratories.
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 part of EN 1568 can also conforms to other parts and
therefore can also be suitable for application as low and/or medium expansion foams.
