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 8116-4 was prepared by Technical Committee ISO/TC 72, Textile machinery and accessories,
Subcommittee SC 3, Machinery for fabric manufacturing including preparatory machinery and accessories.
This third edition cancels and replaces the second edition (ISO 8116-4:1995), which has been technically
revised.
ISO 8116 consists of the following parts, under the general title Textile machinery and accessories — Beams
for winding:
⎯ Part 1: General vocabulary

Part 4:
Test methods and quality classification of flanges for weaver’s
beams, warper’s beams and sectional beams

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 8116-1 and the following apply.
3.1
quality class
classification of beam flanges according to their deformation behaviour under load
3.2
maximum test load
F
max
maximum value of load applied to the beam flange during testing according to its quality class
4 Quality classification
Beam flanges are classified according to four quality classes. The designation of the quality classes is Q1, Q2,
Q3 or Q4.
Depending on the quality class, the beam flanges are loaded with different ultimate loads. These limit values
are given in Clause 6.
For examples of application by quality class, see Annex A.
5 Test methods
5.1 Principle
The beam flange is subjected to a test load and the resulting deformation is measured.
For weaver’s beams, the test load is applied to the flange via a beam barrel. For warper’s beams and
sectional beams, the load is applied to the beam flange via a pressure plate. A pressure ring with a defined
inner diameter is used as an anvil.
The permanent deformation and the plastic deformation of the flange shall not exceed the defined limit values
when the maximum load is applied.
5.2 Apparatus
5.2.1 Press device, with indications for the application of the test load.
5.2.2 Three dial gauges, for determination of deformation of the flange with an accuracy of 0,01 mm.
5.2.3 Measurement device, for joint installation of the three dial gauges on the bearing device, in an angle
of 120° each.
5.2.4 Steel pressure ring.
5.2.5 Beam barrel, for load application (for weaver’s beams).
5.2.6 Pressure plate, for load application (for warper’s beams and sectional beams).
5.3 Testing configuration
For measurement of flange deformation, three dial gauges are installed on the bearing device by means of the
measurement device. These are used to measure the relative path between the outer diameter of the beam
barrel d and the circle diameter d − 20 mm. The dial gauges are staggered by 120°. The testing
2 1
configuration for weaver’s beams is given in Figure 1. The testing configurations for warper’s beams are given
in Figure 2 and Figure 3. The testing configuration for sectional beams is given in Figure 4.
