Rubber hoses and hose assemblies — Rubber-covered spiral-wire-reinforced hydraulic types for oil-based or waterbased fluids — Specification - Third Edition
 N 3862

Annotation

This International Standard specifies requirements for five types of spiral-wire-reinforced hydraulic hose and hose assembly of nominal size from 6,3 to 51. They are suitable for use with water-based hydraulic fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743-4 at temperatures ranging from 40 °C to +60 °C and oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743-4 at temperatures ranging from 40 °C to +100 °C for types 4SP and 4SH and 40 °C to +120 °C for types R12, R13 and R15.

NOTE 1 This temperature rating is related to the water-based hydraulic fluids defined in ISO 6743-4.

This International Standard does not include requirements for end fittings. It is limited to requirements for hoses and hose assemblies.

NOTE 2 It is the responsibility of the user, in consultation with the hose manufacturer, to establish the compatibility of the hose with the fluid to be used.
