  Full Description ADOPTED_FROM:EN ISO 14557:2021 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.
