About This Item
Full Description
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.
