Foreword
The International Organization for Standardization (ISO) 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 (seewww .iso .org/ patents).

ISO 21625:2020(E)

Introduction
Bamboo belongs to the subfamily Bambusoidae of the grass family (Gramineae/Poaceae). There are
nearly 1 642 bamboo species, including 1 521 woody bamboos, distributed naturally in tropical and
warm temperate areas. There are 3 tribes of bamboos, which are Arundinarieae (32 genus); Bambuseae
1
tribe (69 genus); and herb-bamboo dominated by Olyreae tribe (22 genus) . Depending on the species
2
and growing location, most bamboo species can grow rapidly up to 1,2 m per day .
The current utilization of bamboo worldwide is varying from construction to human’s various
necessities, i.e. handicraft, musical instruments, kitchen utensils, fibre-based products (i.e. textile,
shoes, etc.), medicinal treatment, food, etc. Due to increasing bamboo utilization for daily life,
harmonization of the terms used is required in order to minimize confusion or conflicts and attain
universal understanding.
The terms and descriptions contained in this International Standard have been mainly constituted
to represent internationally recognized terms applied to bamboo and bamboo products (semi/
intermediate and final). The descriptions of the terms are created for general understanding by the
bamboo experts, industry, consumers and other stakeholders.
The sources used during this International Standard development have been the most recent
scientific documents and/or standards (international, regional or domestic), either published or under
development. Descriptions sourced from standards are worded as closely as possible to that appearing
in the standards. However, where necessary modifications have been made for several descriptions
following review between standards, a note appears after the term expressing the adaptation of its
description from the standards.
