37、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
38、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 (vegetab
39、le 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 b
40、e 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. T
41、he 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
42、 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
43、 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 ecotoxicolog
44、ical 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. BS EN 15682:2018EN 1568-2:2018 (E) 8 1 Scope This European Standard specifies requirements for chemical and physical pr
45、operties, 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. So
46、me 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. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content const
