1 Modification to the Foreword
Replace the text of the paragraph after the list of standards with:
"As fire fighting foams are chemical agents or chemical preparations the European Directives 1967/548/EEC, 1999/45/EC, Regulation (EC) 1907/2006 (REACH) and Directive 2006/1 22/EC apply and should be taken into account.".
2 Modification to the Introduction
Replace the text of the last paragraph as follows:
"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 versions of European Directives 67/548/EEC, 2006/122/EC and 1999/45/EC and Regulation (EC) 1907/2006 (REACH) apply when considering the testing of ecotoxicological properties and safety in the work environment.".

This document (EN 1568-1:2008) has been prepared by Technical Committee CEN/TC 191 "Fixed firefighting systems", the secretariat of which is held by BSL
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of an identical text or by endorsement, at the latest by September 2008, and conflicting national standards shall be withdrawn at the latest by September 2008.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 1568-1:2000.
This European Standard is one of a series specifying requirements for fire extinguishing media in common use. This series includes the following:
EN 25923, Fire protection — Fire extinguishing media — Carbon dioxide (ISO 5923:1989)
EN 27201-1, Fire protection — Fire extinguishing media — Halogenated hydrocarbons — Part 1: Specifications for halon 1211 and halon 1301 (ISO 7201-1:1989)
EN 27201-2, Fire protection — Fire extinguishing media - Halogenated hydrocarbons — Part 2: Code of practice for safe handling and transfer procedures (ISO 7201-2:1991)
EN 615, Fire protection — Fire extinguishing media — Specification for powders (other than Class D powders)
This standard is Part 1 of EN 1568 which has the general title "Fire extinguishing media - Foam concentrates". The other parts are:
—? Part 2: Specification for high 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.
As fire fighting foams are chemical agents or chemical preparations EC directives 1967/548/EEC, 1999/45/EEC, Regulation (EC) 1907/2006 (REACH) and 2006/60/EEC apply and should be taken into account.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
Introduction
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 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 versions of EC directives 67/548/EEC, 2006/60/EEC, 1999/45/EEC and Regulation (EC) 1907/2006 apply when considering the testing of ecotoxicological properties and safety in the work environment. 1 Scope
This document specifies requirements for chemical and physical properties, and minimum performance requirements of medium expansion foams suitable for surface application to water-immiscible liquids. Requirements are also given for marking.
NOTE 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 high expansion foams.
