| Naslov (EN): | Fire extinguishing media -- Foam concentrates -- Part 4: Specification for low expansion foam concentrates for surface application to water-miscible liquids (EN 1568-4:2008) |
| Područje primjene (EN): | 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. Requirements are also given for marking. IMPORTANT — In this part of the document, 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 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. 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 medium and/or high expansion foams. |
