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).

Introduction
The aim of this document is to provide furniture manufacturers, designers and developers with
comparable information regarding the performance of all types of hinges pivoting on a vertical axis and
their components.
The tests consist of the application of loads, forces and velocities simulating normal functional use, as
well as misuse, that can reasonably be expected to occur.
With the exception of the corrosion test in Clause 6.4, the tests are designed to evaluate properties
without regard to materials, design/construction or manufacturing processes.
The strength and durability tests only relate to the hinges and the parts used for the attachment (e.g.
mounting plates and screws).
The strength and durability tests are carried out in a test frame with specified properties.
The test results are only valid for the hinges tested. These results are used to represent the performance
of production models provided that the tested model is representative of the production model.

4 Test conditions
4.1 General
The hinges shall be assembled/mounted/adjusted according to the instructions supplied with it.
If mounting, assembly or adjustment instructions are not supplied, the most adverse configuration shall
be used and the mounting or assembly method shall be recorded in the test report. Fittings shall be
tightened before testing and shall not be re-tightened unless specifically required in the manufacturer’s
instructions. If the configuration has to be changed to produce the worst-case conditions, this shall be
recorded in the test report.

ISO 4769:2022(E)
The tests shall be carried out in indoor ambient conditions at a temperature between 15 °C to 27 °C. If
during a test the temperature is outside of the range of 15 °C to 27 °C, the maximum and/or minimum
temperature shall be recorded in the test report.
Hinges which include structural hardware parts made of hygroscopic plastic materials (e.g. polyamide)
shall be conditioned at (23 ± 2) °C and at a relative humidity of (50 ± 5) % for 7 days before testing.
[1]
NOTE For accelerating the conditioning process, ISO 1110 can be used.
If a test cannot be carried out as specified, the test shall be carried out as closely as possible to that
specified. Any modification to the test method shall be technically justified and recorded in the test
report. Before beginning testing, visually inspect the hinges and components thoroughly. Record any
defects to eliminate any assumption that they have been caused by the tests. Carry out measurements
if specified.
4.2 Application of forces
The forces in the static load tests shall be applied sufficiently slowly to ensure that negligible dynamic
force is applied. Unless otherwise specified, each force shall be maintained for not less than 10 s and not
more than 15 s.
The forces in durability tests shall be applied at a rate to ensure that excessive heating does not occur.
The forces may be replaced by masses. The relation 10 N = 1 kg shall be used for this purpose.
4.3 Tolerances
Unless otherwise stated, the following tolerances are applicable:
± 5 % of the nominal force;
Forces:
± 5 % of the nominal velocity;
Velocities:
± 1 % of the nominal mass;
Masses:
± 1 mm of the nominal dimension;
Dimensions:
± 2° of the nominal angle.
Angles:
The accuracy for the positioning of forces shall be ± 5 mm.
NOTE For the purposes of uncertainty of test, test results are not considered to be adversely affected when
the above tolerances are met.
4.4 Sequence of testing
The tests shall be carried out in the same sequence as the clauses are numbered in this document. If the
clause sequence
