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 4671 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 4671:1999), which has been technically
revised. The main changes are the following:
⎯ a clause has been added (Clause 3) specifying details of test piece conditioning and temperature of
measurement;
⎯ in 4.2, the use of tapered gauges has been added;
⎯ in Clause 4, an additional method of measuring the inside diameter has been included (4.8);
⎯ in Clause 5, an additional method of measuring the outside diameter has been included (5.6);
⎯ in 7.1, the parts of hoses at which readings are to be taken have been specified;
⎯ in 8.1, the parts of the hoses at which readings are to be taken have been specified;
⎯ in Clause 8, three additional methods of measuring the concentricity have been included (8.4, 8.5
and 8.6);
⎯ in 9.2, the method of measuring the lining and cover thickness has been modified.

INTERNATIONAL STANDARD ISO 4671:2007(E)
Rubber and plastics hoses and hose assemblies — Methods of
measurement of the dimensions of hoses and the lengths of
hose assemblies
1 Scope
This International Standard specifies methods of measuring the inside diameter, outside diameter (including
diameter over reinforcement of hydraulic hoses), wall thickness, concentricity and lining and cover thickness
of hoses, methods of measurement and identification of the lengths of hoses and hose assemblies, and a
method of verifying the through-bore of hydraulic hose assemblies.
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.

metrological characteristics of mechanical dial gauges

ISO 3611, Micrometer callipers for external measurement
3 Test piece conditioning and temperature of measurement
3.1 Conditioning of test pieces
Unless otherwise specified, test pieces shall be taken at least 16 h after manufacture of the hose and
+°7
conditioned at 23 C for at least 3 h before measurement. This 3 h may be included in the 16 h.

3.2 Measurement temperature
+7
Unless otherwise specified, the measurement temperature shall be 23 °C.

4 Measurement of inside diameter
4.1 General
Measurements by methods 1 to 7 may be made either on the ends of a full length of hose or on a test piece
(minimum length 150 mm) cut from a full length. For wire-reinforced hydraulic hoses, measurements shall be
made at a minimum distance of 25 mm from the end of the hose.
Measurements shall be made using one of the following methods, as appropriate.

4.2 Method 1
For inside diameters less than 150 mm and for all sizes of collapsible hose, plug gauges with 0,25 mm
increments in diameter (see Figure 1) and tapered gauges with 0,1 mm increments in diameter (see Figure 2)
may be used. Insert the gauge into the hose test piece gently without pressure. Take special care if the hose
bore is not precisely circular.

Figure 2 — Tapered gauges
4.3 Method 2
For inside diameters less than 63 mm, where greater accuracy is required, for example for wire-reinforced
hydraulic hoses, an expanding ball or telescopic gauge may be used.
4.4 Method 3
For all inside diameters up to and including 100 mm, the internal jaws of vernier slide callipers complying with
the requirements of ISO 3599 may be used. Make two measurements at right angles to each other and take
their average as the inside diameter. Take care not to distort the hose when making the measurements.
Callipers of suitable size may be used for nominal bores above 100 when greater accuracy than is obtainable
by Method 5 (see 4.6) is required.
4.5 Method 4
For all inside diameters, an internal calliper dial gauge (see ISO 463) with rounded feet designed for use
