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 Electro technical Commission (IEC) on all matters of electro
technical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part1. 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, Part2 (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.
For an explanation on the meaning of ISO specific terms and 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 URL: www .iso .org/ iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 296, Bamboo and Rattan.
Any feedback or questions on this document should be directed to the user’s national standards body. A

4 Requirements
4.1 Appearance requirements
The material used for the bamboo flooring shall be free from physical damage, decay and insect attack.
There will be variations from element to element, but the total impression of the installed floor shall
show a homogeneous character.
Any part of the material that impedes preservation, bonding and finishing shall be removed entirely.
As bamboo is a natural material, colour variations may occur, also due to an effect of light over time.
