The work of preparing International Sta
10、ndards 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
11、take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted
12、 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
13、rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 22389-1 was prepared by Technical Committee ISO/TC165, Timber structures. ISO 22389 consists of the following part, under the general title Timber structures Bending strength of I-beams: Part 1: Testing, eva
14、luation and characterization Component performance and manufacturing requirements is to form the subject of a part 2. This part of ISO 22389 is based, with permission of ASTM International, on ASTM D 5055, Standard Specification for Establishing and Monitoring Structural Capacities of Prefabricated
15、Wood I-Joists, copyright ASTM International. ISO 22389-1:2010(E) ISO 2010 All rights reserved vIntroduction Prefabricated wood-based I-beams are being produced in many countries under different national standards and these products are being exported from one country to another. While the national s
16、tandards have many similarities, there are also many areas of dissimilarity. Consequently, there is need for the development of an International Standard to establish consistency between these standards to ensure the suitability of prefabricated wood-based I-beams for structural end-use applications
17、 regardless of country of manufacture or country of end use. It is intended that the development of this part of ISO 22389 will have value to industry, consumers, governments and distributors.

18、 of I-beams Part 1: Testing, evaluation and characterization 1 Scope This part of ISO 22389 specifies the requirements for prefabricated wood-based I-beams used as structural members in bending applications. It gives procedures for establishing and evaluating structural capacities of prefabricated w
19、ood-based I-beams. The capacities considered are shear, moment, stiffness, bearing, and flange tension and compression. Procedures for establishing common details are given and certain end-use considerations specific to wood- based I-beams are itemized. Wood-based I-beams tested according to this pa
20、rt of ISO 22389 are intended for use under covered conditions and utilize components that are able to resist the effects of moisture on structural performance due to construction delays or other conditions of similar severity, but are not intended to be permanently exposed to the weather. This part
21、of ISO 22389 is not applicable to fire performance, formaldehyde requirements and biological durability. It does not cover manufacturing requirements for prefabricated wood-based I-beams. NOTE Procedures set out in this part of ISO 22389 are applicable to I-beams defined by a standard or a manufactu
22、rers specification that includes requirements for the flanges, webs and bonding, and production controls, including ongoing conformity assessment. This part of ISO 22389 does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of t
23、his part of ISO 22389 to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. A specific precautionary statement is given in 5.1.5. 2 Normative references The following referenced documents are indispensable for the application of
24、this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
