BSI BS 6391: Specification for non-percolating layflat delivery hoses and hose assemblies for fire fighting purposes
SDO: BSI: British Standards Institution
DOD Adopted ANSI Approved Approved
This British Standard specifies requirements for types 1, 2 and 3 of non-percolating layflat delivery hoses for fire fighting purposes, which are intended for use at working pressures not exceeding 15 bar, and at a minimum ambient temperature of -20 °C.
The hoses covered are suitable for use with fire hose couplings conforming to BS 336. Additional requirements are specified for hose assemblies, which are hoses supplied with couplings conforming to BS 336 already fitted.
NOTE 1 The working pressure of the hoses in service will not normally exceed 10 bar, but they can be used at pressures up to 15 bar, e.g. when connected to high rise mains.
NOTE 2 1 bar = 105 N/m2 = 105 Pa. All pressure values specified in this standard are gauge pressures.
NOTE 3 BS EN 14540 specifies requirements for non-percolating layflat hoses for fixed systems. Requirements for semi-rigid hoses are given in BS EN 1947 for pumps and vehicles and in BS EN 694 for fixed systems.
Annex A gives recommendations for the pressure testing of hoses in service. Annex B specifies the minimum frequency of tests.
