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.<\/p>\n

\n
\n NOTE\n <\/div>\n

All pressures are expressed in megapascals and in bar (1 MPa = 10 bar).<\/p>\n<\/div>\n

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<\/span>).<\/p>\n

Type A (rubber) hoses are intended for use at a minimum temperature of ?20 \u00b0C and Type B (thermoplastics) hoses are intended for use at a minimum temperature of ?10 \u00b0C.<\/p>\n
