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.
NOTEÂ Â Â Â Â Â All pressures are expressed in megapascals and in bar (1Â MPaÂ =Â 10Â 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 ClauseÂ 8).
TypeÂ A (rubber) hoses are intended for use at a minimum temperature of â20Â Â°C and TypeÂ B (thermoplastics) hoses are intended for use at a minimum temperature of â10Â Â°C.
