8、1:2004(E) iv ISO 2004 All rights reservedForeword 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 b
9、ody 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
10、technical 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
11、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 r
12、ights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 22157-1 was prepared by Technical Committee ISO/TC 165, Timber structures, in collaboration with INBAR, International Network for Bamboo and Rattan. ISO 22157 consists of the following parts, under the genera
13、l title Bamboo Determination of physical and mechanical properties: Part 1: Requirements Part 2: Laboratory manual ISO 22157-1:2004(E) ISO 2004 All rights reserved vIntroduction This part of ISO 22157 was originally prepared and submitted by INBAR, the International Network for Bamboo and Rattan, wh
14、ich is an international agency with its head office in Beijing. The aim is to bring bamboo towards the level of an internationally recognized and accepted building and engineering material. INBAR aims to do so in favour of the well-being of lower income groups in developing countries, and in favour
15、of a better environment in bamboo-growing countries. Discussion about the need of an International Standard started already in 1988, during the International Bamboo Workshop in Cochin, India. Due to lack of funds, the real work started as late as in 1997, when INBAR was launched as an International
16、Agency, and when the Dutch Government provided the required funding. In 1998, draft texts were written and distributed to a group of specialists inside INBAR who acted as volunteers and spent their time and expertise to propose improvements. Members of this group met for the first time in a meeting
17、on 30-31 October 1998 in San Jos, Costa Rica. Participants were N.S. Adkoli, K. Ghavami, R. Gnanaharan, H.N.S. Jagadeesh, J.J.A. Janssen, K.S. Pruthi, I.V. Ramanuja Rao, D. Sands, J.O. Siopongco, K. Stochlia and D. Tingley. During 1999, the results from this meeting were incorporated in the draft te
18、xts. In September, these were discussed in a meeting with ISO/TC 165 in Harbin, China. In October 1999, a meeting took place with representatives of the National Standard Institutes of Bangladesh, China, Colombia, Ecuador, Ethiopia, India, Indonesia, Nepal, Philippines, Tanzania, Thailand and Vietna
19、m. This meeting was held at FPRDI in Los Baos, Philippines. The outcome of this meeting was a considerable improvement of the texts, and a general agreement to submit the draft texts to ISO for the formal procedure. Besides INBAR, CIB (especially committee W 18 B) has also been involved in the prepa
20、ration. Discussions during meetings of W 18 B (e.g. Singapore 1987 and Kuala Lumpur 1992) have greatly contributed. Because this part of ISO 22157 is the first Iinternational Standard on bamboo, it does not cancel or replace other documents in whole or in part, besides the draft documents prepared a
21、nd distributed for internal discussion by INBAR during 1998 and 1999. For similar reasons, significant technical changes from previous editions apply only to these previous draft documents.

22、mechanical properties Part 1: Requirements 1 Scope This part of ISO 22157 specifies test methods for evaluating the following characteristic physical and strength properties for bamboo: moisture content, mass per volume, shrinkage, compression, bending, shear and tension. This part of ISO 22157 cove

The data can also be used to establish the relationship between mechanical properties and factors, such as moisture content, ma
