BS ISO 1436:2020 pdf download.Rubber hoses and hose assemblies - Wire-braid-reinforced hydraulic types for oil-based or water-based fluids - Specification
1 Scope
This document specifies requirements for six types of wire-braid-reinforced hoses and hose assemblies of nominal size from 5 to 51. This document also specifies the hose of nominal size 63 for types 2SN and R2AT, and the hose of nominal size 76 for type 2SN.
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 —40 °C to +70 °C;
— water at temperatures ranging from 0 °C to +70 °C.
This document does not include requirements for end fittings. It is limited to requirements for hoses and hose assemblies.
NOTE 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.

5.1 Hoses
Hoses shall consist of a rubber lining resistant to oil- or water-based hydraulic fluids or water, one or two layers of high-tensile steel wire and a weather- and oil-resistant rubber cover.
5.2 Hose assemblies
Hose assemblies shall be manufactured using hoses that conform to the requirements of this document.
Hose assemblies shall be manufactured only with those hose fittings whose correct functioning has
been verified in accordance with 7.2, 7.4, 7.5 and 7.6. The manufacturer's instructions shall be followed for the preparation and fabrication of hose assemblies.BS ISO 1436 pdf download.
