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 8033 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee
SC 1, Hoses (rubber and plastics).
This third edition cancels and replaces the second edition (ISO 8033:1991), Clause 5, Subclause 6.3, Table 1
and Figure 8 of which have been technically revised.

INTERNATIONAL STANDARD ISO 8033:2006(E)

Rubber and plastics hoses — Determination of adhesion
between components
1 Scope
Adequate adhesion between the various components of a hose is essential if it is to perform satisfactorily in
service. This International Standard specifies methods for the determination of the adhesion between lining
and reinforcement, between cover and reinforcement, between reinforcement layers, between cover and outer
lamination (thin layer of material outside the cover for protection) and between lining and inner lamination (thin
layer of material inside the lining to reduce permeation of fluid into the lining). It covers all bore sizes and the
following types of hose construction:
⎯ woven textile fabric;
⎯ braided textile fabric;
⎯ knitted textile fabric;
⎯ circular-woven textile fabric;
⎯ textile spiral;
⎯ textile cord;
⎯ wire braid;
⎯ wire spiral;
⎯ hoses containing a supporting helix.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

and adhesion strength
ISO 23529, Rubber — General procedures for preparing and conditioning test pieces for physical test

ISO 8033:2006(E)
3 Principle
Using test pieces of standard dimensions, the adhesion strength between lining and reinforcement, between
cover and reinforcement, between reinforcement layers, between cover and outer lamination and between
lining and inner lamination is measured under specified conditions.
4 Apparatus
A test machine having the following characteristics is required:
4.1 Test machine
The machine shall be power driven, equipped with a suitable dynamometer, capable of maintaining a
substantially constant rate of traverse of the moving head during the test and fitted with an autographic
recorder. It shall comply with the requirements for class 0,5 or 1 of ISO 5893:2002.
An inertialess dynamometer shall be used.
4.2 Grips
The grips shall be capable of holding the test piece without slippage.
Self-tightening grips are recommended.
For strip test pieces, provision shall be made to maintain the strip in the appropriate plane of the grips during
the test, for example by attaching sufficient weights to the free end of the test piece or by fitting a supporting
plate, coated with a low-friction material such as polytetrafluoroethylene (PTFE), to the non-driven grip.
4.3 Mandrel
For testing ring test pieces (type 6 and type 8), a mandrel shall be provided that is a close sliding fit in the test
piece. This mandrel shall be capable of being fitted into the driven head of the machine so that it will rotate
freely during the test.
5 Test pieces
5.1 Types of test piece
5.1.1 General
Eight types of test piece are specified to cover the range of hose constructions and bore sizes normally
encountered (see Figures 1 to 8).
5.1.2 Type 1
Strip, cut from the hose as a 25 mm ± 0,5 mm wide ring which is then cut transversely to form a strip.
5.1.3 Type 2
Strip, 160 mm × half the hose circumference.
5.1.4 Type 3
Strip, cut from the hose as a 35 mm ± 2 mm wide ring which is then cut transversely to form a strip.
