ISO 3862 standard is for Rubber hoses and hose assemblies, Rubber-covered spiral-wire-reinforced hydraulic types for oil-based or water-based fluids Specification.
This ISO 3862 document 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:
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 3862 Classification
Five types of hose are specified, distinguished by their construction, working pressure and oil
resistance:
Type 4SP: medium-pressure hoses with four plies of steel wire spiral.
Type 4SH: high-pressure hoses with four plies of steel wire spiral.
Type R12: heavy-duty high-temperature hoses with a medium-pressure rating having four plies of steel wire spiral.
Type R13: heavy-duty high-temperature hoses with a high-pressure rating having a multiple-steel-wire spiral.
Type R15: heavy-duty high-temperature hoses with an extra-high-pressure rating having a multiple-steel-wire spiral.
