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

expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This document was prepared by ISO/TC 136, Furniture.
This second edition cancels and replaces the first edition (ISO 9098-2:1994), which has been technically
revised.
The main changes are as follows:
— modification of the title;
— expansion of the scope;
— increase of apparatus and test procedures;
— revision of general test requirements and test report.
A list of all parts in the ISO 9098 series can be found on the ISO website.

INTERNATIONAL STANDARD ISO 9098-2:2023(E)
Bunk beds and high beds — Safety requirements and
tests —
Part 2:
Test methods
1 Scope
This document specifies test methods for the safety, strength and durability of bunk beds and high
beds for domestic and non-domestic use.
The tests apply to beds with an internal length greater than 1 400 mm and a maximum bed base width
of 1 200 mm, and with the upper surface of a bed base 600 mm or more above the floor.
The tests are designed to be applied to a bed that is fully assembled and ready for use.
The applicable safety requirements are given in ISO 9098-1:2023.

4 General test requirements
4.1 Preliminary preparation
Unless otherwise specified by the manufacturer, the test item shall be stored in indoor ambient
conditions for at least 24 h immediately prior to testing.
The sample shall be tested as delivered. Knock-down beds shall be assembled according to the
manufacturer’s instructions. If the instructions allow the bed to be assembled or combined in different
ways, the most adverse combination shall be used for each test. Knock-down fittings shall be tightened
before testing. Further tightening shall not take place unless specifically required by the manufacturer.
If the configuration shall be changed to produce the worst-case conditions, this shall be recorded in the
test report.
The test shall be carried out in indoor ambient conditions at a temperature between 15 °C and 27 °C. If,
during a test, the temperature falls outside of the range of 15 °C to 27 °C, the maximum and/or minimum
temperature shall be recorded in the test report.
The tests shall be carried out on the same sample and follow the order of the clauses in ISO 9098-1:2023.
If a test cannot be carried out as specified in this document, e.g. because a loading pad cannot be used
for t
