This European Standard specifies the tests to be carried out in order to assess the suitability of foam concentrates used to produce medium expansion foam (made from foam concentrates conforming to prEN 1568-1) or high expansion foam (made from foam concentrates conforming to prEN 1568-2) and fire extinguishing powder conforming to EN 615 when used alone or in combination on liquefied natural gas (LNG) fires. This standard does not specify the general requirements for foam concentrates given in prEN 1568-1 and prEN 1568-2 or fire extinguishing powder given in EN 615.
