Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 1436-2 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee
SC 1, Hoses (rubber and plastics).
Together with Part 1 (see below), this part of ISO 1436 cancels and replaces ISO 1436:1991, which has been
technically revised.
ISO 1436 consists of the following parts, under the general title Rubber hoses and hose assemblies — Wire-
braid-reinforced hydraulic types ― Specification:
⎯ Part 1: Oil-based fluid applications
⎯ Part 2: Water-based fluid applications

Rubber hoses and hose assemblies — Wire-braid-reinforced

Part 2:
Water-based fluid applications
1 Scope
This part of ISO 1436 specifies requirements for six types of wire-braid-reinforced hose and hose assembly of
nominal size from 5 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.
This part of ISO 1436 does not include requirements for end fittings. It is limited to requirements for the
performance of 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.

3 Classification
Six types of hose are specified, distinguished by their construction, working pressure and oil resistance:
⎯ Type 1ST: hoses with a single braid of wire reinforcement and having a thick cover.
⎯ Type 2ST: hoses with two braids of wire reinforcement and having a thick cover.
⎯ Types 1SN and R1AT: hoses with a single braid of wire reinforcement and having a thin cover.
⎯ Types 2SN and R2AT: hoses with two braids of wire reinforcement and having a thin cover.
NOTE Types 1SN and R1AT and types 2SN and R2AT have the same reinforcement dimensions as type 1ST and
type 2ST, respectively, except that they have thinner covers designed to assemble with fittings without removal of the
cover or a portion of the cover.
4 Materials and construction
4.1 Hoses
Hoses shall consist of a rubber lining resistant to water-based hydraulic fluids, one or two layers of high-
tensile steel wire and a weather- and oil-resistant rubber cover.
4.2 Hose assemblies
Hose assemblies shall be manufactured using hoses conforming to the requirements of this part of ISO 1436.
Hose assemblies shall be manufactured only with those hose fittings whose correct functioning has been
verified in accordance with Subclauses 6.2, 6.4, 6.5 and 6.6 of this part of ISO 1436. The manufacturer's
instructions shall be followed for the preparation and fabrication of hose assemblies.
5 Dimensions
5.1 Hose diameters, cover thickness and hose concentricity
When measured in accordance with ISO 4671, the hose diameters and the cover thickness (where
appropriate) shall conform to the values given in Table 1.
When measured in accordance with ISO 4671, the concentricity of hoses shall conform to the values given in
Table 2.
