Description

This document gives requirements and test methods for rubber and plastics suction hoses for fire‑fighting purposes.

NOTE 1

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.

NOTE 2

Hoses for use at temperatures lower than those specified above can be supplied by agreement between the manufacturer and purchaser. In this case, the low temperature flexibility test (see 6.3) should be carried out at the specified temperature.
