Fire-fighting hoses - Non-percolating layflat delivery hoses and hose assemblies for pumps and vehicles prEN 1924

Scope

This European Standard specifies the requirements and test methods for non-percolating layflat delivery hoses for fire fighting purposes.
The standard applies exclusively to delivery hoses for fire-fighting purposes intended for use at a minimum ambient temperature of -20 °C in normal conditions, and a minimum ambient temperature of -30 °C in 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 (see clause 10) and also for high pressure hoses (see clause 7).
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.
NOTE 1 A moisture absorption test can be specified by agreement between the manufacturer and the purchaser.
NOTE 2 All pressures are gauge pressures and are expressed in megapascals. 1 MPa = 10 bar.
