Standards Development
This document specifies requirements for chemical and physical properties, and minimum performance requirements of low expansion foams suitable for surface application to water-miscible liquids. This document also specifies requirements for marking.
IMPORTANT - The fire performance is tested using acetone and isopropanol as the fuel, which also forms the basis for the performance classification. However, there are a large number of water-miscible liquids which have more or less different properties to acetone and isopropanol. It has been shown by tests using other fuels that the performance of various foams can differ considerably. Examples of such fuel is Methyl Ethyl Ketone (MEK). It is therefore essential that the user checks for any unfavourable or unacceptable loss of efficiency when the foam is used against fires in any other water-miscible fuels than acetone and isopropanol respectively. The fire test conditions and procedure given in H.2 can be used in order to achieve results comparative with acetone and isopropanol respectively and related requirements.
It is also essential for the user to note that other fuel depths and methods of application than those specified in Clause H.2 can cause considerable loss of efficiency and these matters should be carefully considered by the user when assessing the suitability for particular applications.
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 the EN 1568 series can also conform to other parts and therefore can also be suitable for application as medium and/or high expansion foams.
A revision of series EN 1568:2018 is needed to bring it up to date and align it with test requirements of similar standards. EN 1568 is no longer useable to non-fluorinated systems, as AFFF foams are being phased out.
The issues are highlighted and documented in CEN/TC 191/WG 3 N 12 and N 18 (See CEN/TC 191 N1917). See also meeting minutes of 8th meeting of CEN/TC 191/WG 3 (N 22; see CEN/TC 191 N1917) and the 9th meeting.
