    11、 rservs/ iiiISO 24294:2013(E/F/R)ForewordISO (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 inter

    12、ested 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

    13、 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 by the tech

    14、nical 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 rights. ISO s

    15、hall not be held responsible for identifying any or all such patent rights.ISO 24294 was prepared by Technical Committee ISO/TC 218, Timber.This edition cancels and replaces ISO 4473:1988, ISO 4474:1989, ISO 4476:1983 and ISO 8966:1987.iv ISO 2013 All rights reserved/Tous droits rservs/ ISO 24294:20

    16、13(E/F/R)IntroductionWood is a naturally occurring resource and is the only major construction material that is renewable. Because it is renewable, the use of wood and the many different timber products made from wood, contributes to overall sustainable development. Wood is used in the manufacture o

    17、f various timber products and many of these timber products are intended specifically for use both as structural and non-structural elements in the construction of timber-framed or platform-frame buildings.NOTE 1 In North America, timber-framed buildings in which timber is the main structural materi

    18、al are commonly referred to as post and beam construction, while other timber-framed buildings constructed of wood that rely wholly or mainly on load-bearing walls that have studs supported by the floor(s) are typically referred to as wood frame construction or platform frame construction.Similar to

    19、 most other building materials, wood has unique properties. In wood, these various properties are affected by species, natural growth characteristics and moisture content and with its unique cell structure; wood has different strength properties in different grain directions.There is a need to be ab

    20、le to conceptualize and communicate on the physical and mechanical characteristics of the many different hardwood and softwood round, sawn and processed timbers in a manner that is consistent and recognized globally.This International Standard has been prepared by the various groups involved in the

    21、timber industry, such as manufacturers, builders, wholesalers and importers, as well as research organizations, academia, national regulatory bodies, standards developers and professional design organizations.Understanding the nature of the various physical characteristics and features of round and

    22、sawn timber will enable effective communication related to sawn and processed timber in a manner that is consistently understood by and equitable to all active and potential traders/users. Its use in other standards will also aid harmonization and provide a basis for specialist terminology.NOTE 2 Ge

    23、neral and specific concepts regarding wood and timber that are used in communication and discussions related to building and civil engineering works have been defined in ISO 6707-1:2004.The terms are presented in the three official ISO languages (English, French and Russian) using a systematic struc

    24、ture to allow ready comparison of related concepts and to reflect the underlying concept system. Where a given term is used to represent different concepts, creating homonymy between them, each concept is treated in separate terminological entries, with a notational cross-reference to the other entr

    25、y included in both. ISO 2013 All rights reserved/Tous droits rservs/ vTimber Round and sawn timber Vocabulary1 ScopeThis International Standard contains the terms and definitions of concepts to establish a multilingual vocabulary of terminology to be applied in forest and wood working spheres, with

    26、the scope of identification of a tree and of its parts in round and sawn aspects; its measurements; grading; condition; features; sizes; and the natural, biological and infestational defects of wood.2 Normative referencesThere are no normative references for this standard.3 General - Round timber an

Where the term timber is used in North America to refer to a specific end-use product, it generally refers to sawn lumber (see 5.1) that is 114 mm (no

    30、minal 5 in) or greater in thickness.Note 3 to entry: In the Russian language, the term “timber” does not refer to standing trees or felled trees.3.3speciesdistinct sort or kind of tree having some characteristics or qualities in common that distinguishes it from othersEXAMPLE Douglas fir (Pseudotsug

    31、a menziessi), Eastern white pine (Pinus strobus), White spruce (Picea glauca), Scots pine (Pinus silvestris), Silver fir (Abies alba).Note 1 to entry: A species of wood(3.1) is usually referred to by a common name, but typically identified by a botanical name that is often based on a Linnaean binomi
