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.
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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO’s adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This document was prepared by Technical Committee ISO/TC 45, Rubber and rubber products,
Subcommittee SC 1, Rubber and plastics hoses and hose assemblies.
This fifth edition cancels and replaces the fourth edition (ISO 1436:2009), which has been technically
revised. It also incorporates the Technical Corrigendum ISO 1436:2009/Cor. 1:2010.
The main changes compared to the previous edition are as follows:
— Clause 1 has been updated to be more precise;
— Clause 2 has been updated: ISO 4672 has been deleted and replaced by ISO 10619-2, and ISO 10619-1
has been added;
— 8.1 has been revised: year of publication of a standard shall be included in the marking if previous
edition is used.

INTERNATIONAL STANDARD ISO 1436:2017(E)
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 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:
— 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.
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 defines a type S as having the same dimensions and
construction as the type R1AT and type R2AT, which were specified in ISO 1436-1:2001 and ISO 1436-2:2005, but
with 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 high-tensile steel wire and a weather- and oil-resistant rubber cover.
5.2 Hose assemblies
Hose assemblies shall be manufactured using hoses conforming 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.
