This document establishes the requirements and test methods for rubber and plastics suction hoses for fire-fighting purposes. These hoses can also be used manually to supply unpressurized water to the pump or for water discharge.
NOTE - All pressures are expressed in megapascals and in bar (1 MPa = 10 bar).
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 8).
Type A (rubber) hoses are intended for use at a minimum temperature of -20 °C and Type B (thermoplastics) hoses are intended for use at a minimum temperature of -10 °C.
