scope:

Specifies the requirements and test methods for non-percolating layflat delivery hoses for fire fighting purposes. It applies exclusively to delivery hoses for fire-fighting puposes intended for use at a minimum ambient temperature of -20 °C in normal conditions, and a minimum ambient temperature of -30 °C ub colder climatic conditions. Hoses conforming to this standard should be used with fire hose couplings conforming to the relevant national standards for couplings. Class 2 hoses have higher heat resistance, higher abrasion resistance and higher mass than class 1 hoses. Class 4 hoses have higher heat resistance, higher abrasion resistance and higher mass than class 3 hoses, and both these classes have oil contamination resistance. Additional requirements are specified for hose assemblies; that is, hoses with couplings already fitted, where this is carried out by the hose manufacturer and also for high pressure hoses. Hoses in marine applications and/or aggressive environments to be used with wall hydrants as specified in EN 671-2 can conform to the requirements of either this standard or prEN 14540, but this standard is preferred in these applications.
