ISO 4079 standard is for Rubber hoses and hose assemblies Textile-reinforced hydraulic types for oil-based or water-based fluids specification.
This ISO 4079 document specifies requirements for five types of textile-reinforced hydraulic hose and hose assembly of nominal size from 5 to 100.
They are suitable for use with:
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;
Water based fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743-4 at temperatures ranging from 0 °C to +60 °C
Water at temperatures ranging from 0 °C to +60 °C
This document does not include requirements for end fittings. It is limited to requirements for hoses and hose assemblies
ISO 4079 Classification
Five types of hose are specified, distinguished by their construction, working pressure and minimum
Type 1TE: hoses with a single braid of textile reinforcement.
Type 2TE: hoses with one or more braid(s) of textile reinforcement.
Type 3TE: hoses with one or more braid(s) of textile reinforcement (higher working pressure).
Type R3: hoses with two braids of textile reinforcement.
Type R6: hoses with a single braid of textile reinforcement.
