CEN/TC 191/WG 3 - Fire extinguishing media - Foam

This European Standard specifies requirements for chemical and physical properties, and minimum performance requirements of low 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 medium and/or high expansion foams, and for application at low expansion to water-miscible 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.

This European Standard specifies requirements for chemical and physical properties, and minimum performance requirements of low expansion foams suitable for surface application to water-miscible liquids. Requirements are also specified 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 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.

TC - Update of two Directive references in the § below the standards list of the Foreword and in the last § of the Introduction; the update of the references has been suggested by one of the national members during Vote, but has been rejected by TC during CA/7
AFNOR - Harmonizing the wording of the French §§ which differ between the four parts (additional to the changes requested by TC) and correction of text in the 1st sentence of H.2.1.1
DIN - Changing the requirement in the German version of the Introduction into recommendation/statement as in the E+F versions and to avoid un-allowed normative reference on European Directives; additional corrections in the steel designation of H.2.1.1, 1st sentence and correction of text in E.3.2, 3rd §, 1st sentence

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 resepectively. The fire test conditions and procedure given in J.2 can be used in order to achieve results comparative with acetone and isopropanol resepectively and related requirements.
It is also essential for the user to note, that other fuel depths and methods of application than those specified in I.2, can cause considerable loss of efficiency and these matters should be carefully considered by the user when assessing the suitability for particular applications.
