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 non­governmental, 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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

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. Details of any

patent rights identified during the development of the document will be in the Introduction and/or on

the ISO list of patent declarations received (see www.iso.org/patents).

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 1436:2015(E)
Rubber hoses and hose assemblies — Wire-braid-
reinforced hydraulic types for oil-based or water-based
fluids — Specification
1 Scope

This International Standard specifies requirements for six types of wire-braid-reinforced hose and hose

assembly of nominal size from 5 to 51 plus, for one of the five types (type R2ATS), nominal size 63.

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 to −40 °C to +60 °C or 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.

This International Standard 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.

4 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 R1ATS: hoses with a single braid of wire reinforcement and having a thin cover.

— Types 2SN and R2ATS: hoses with two braids of wire reinforcement and having a thin cover.

NOTE Types 1SN and R1ATS and types 2SN and R2ATS 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. SAE J 517, Hydraulic Hose, defines a type S as having the same

dimensions and construction as the type R1AT and type R2AT which were specified in ISO 1436:2009, but at a

higher maximum working pressure. This document uses type R1ATS and type R2ATS to represent these hose

types.
5 Materials and construction
5.1 Hoses

Hoses shall consist of a rubber lining resistant to oil- or water-based hydraulic fluids, one or two layers

of high­tensile steel wire and a weather­ and oil­resistant rubber cover.
5.2 Hose assemblies

Hose assemblies shall be manufactured using hoses conforming to the requirements of this International

Standard.

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 of this International Standard. The manufacturer’s

instructions shall be followed for the preparation and fabrication of hose assemblies.

6 Dimensions
6.1 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.
