ISO 4642-2:2015 applies to delivery hoses for fire-fighting purposes intended for use at a minimum ambient temperature of −20 °C.
Hoses conforming to this part of ISO 4642 are intended to be used with fire hose couplings conforming to the relevant national standards couplings.
Requirements are also given for hose assemblies (see 6.12) where these are fitted by the hose manufacturer.
NOTE 1 Hoses for use at temperatures lower than −20 °C can be supplied by agreement between the manufacturer and purchaser.
NOTE 2 All pressures are expressed in megapascals where 1 MPa = 10 bar.
