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

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 3862:2015(E)
Rubber hoses and hose assemblies — Rubber-covered
spiral-wire-reinforced hydraulic types for oil-based or
water-based fluids — Specification
1 Scope
This International Standard 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 water-based
hydraulic fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743-4 at temperatures ranging from −40 °C
to +60 °C and 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 for types 4SP and 4SH and −40 °C to +120 °C for types R12, R13 and R15.
NOTE 1 This temperature rating is related to the water-based hydraulic fluids defined in ISO 6743-4.
This International Standard does not include requirements for end fittings. It is limited to requirements
for hoses and hose assemblies.
NOTE 2 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.

steel­wire spiral.
5 Materials and construction
5.1 Hoses
Hoses shall consist of a rubber lining resistant to oil- or water-based hydraulic fluids, spiral plies of steel
wire wrapped in alternating directions, and an oil­ and weather­resistant rubber cover. Each spiral wire
ply shall be separated by an insulating layer.
5.2 Hose assemblies
