It was prepared by Technical Committee B/500, Basic data. A list
6、of organizations represented on this committee can be obtained on request to its secretary.SupersessionThis part of BS 6100 supersedes BS 6100-4.1:1992, BS 6100-4.2:1984, BS 6100-4.3:1984, BS 6100-4.4:1992 and BS 6100-4.5:1984, which are withdrawn.Relationship with other publicationsBS 6100 consists
7、 of the following parts. Part 0: Introduction and index.Part 1: General. Part 2: Spaces, building types, environment and physical planning. Part 3: Civil engineering General. Part 4: Civil engineering Transport. Part 5: Civil engineering Water engineering, environmental engineering and pipelines. Pa
8、rt 6: Construction parts.Part 7: Services. Part 8: Work with timber and wood-based panels. Part 9: Work with concrete and plaster. Part 10: Contract terms. Part 11: Performance characteristics, measurement and joints. Part 12: Plant, equipment and persons.Information about this documentBS 6100 has b
9、een completely restructured and compiled on different principles than previously. Consequently, this part of BS 6100 represents a full revision of the standard.A general introduction to and explanation of the BS 6100 vocabulary is given in BS 6100-0, which provides an alphabetical index of all the t
10、erms in all parts of BS 6100. It is intended that individual parts of BS 6100 are used in conjunction with BS 6100-0 because they do not contain indexes themselves.BS 6100-1 reproduces verbatim ISO 6707-1 and provides a vocabulary of general terms for the building and civil engineering industry. It
11、is essential that individual parts of BS 6100 are read in conjunction with BS 6100-1.BS 6100 does not repeat (or provide alternatives for) terms defined in other standards or in other parts of BS 6100. However, it does refer to where definitions can be found and includes a bibliography of all refere
12、nced standards. BSI 2007 iiiBS 6100-8:2007Presentational conventionsDetails of the structure, layout and presentational conventions used in this part of BS 6100 are given in Clause 2.Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of a co
13、ntract. Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legal obligations.iv BSI 2007 This page deliberately left blankBS 6100-8:2007 BSI 2007 1BS 6100-8:20071 ScopeThis part of BS 6100 defines terms that relate to timber and wood-base
14、d panels, including carpentry and joinery.This standard does not define terms for structural members (covered in BS 6100-4) and parts of buildings (covered in BS 6100-7).2 Vocabulary structureThis part of BS 6100 does not contain its own index. Instead, a comprehensive index of terms is given in BS
15、6100-0. As a result, it is intended that this part of BS 6100 is used in conjunction withBS 6100-0.The layout of this vocabulary is designed in accordance with ISO 10241 with terms arranged in a classified order and numbered in accordance with ISO 2145.Each term has an individual number consisting o
16、f seven digits in two parts, the first of two digits, the second of five. Each number tells the following information about the term.a) The first two digits represent which part of BS 6100 the term belongs to.b) The third digit represents which group of terms it belongs to within the part.c) The fou
17、rth digit represents which subgroup of terms it belongs to within the group, as follows.1) Works.2) Parts.3) Materials.4) Activities.5) Processes.6) Plant, equipment and documentation.7) Properties.8) Spaces.9) Miscellaneous.d) The fifth to seventh digits determine the location of the term within th
18、e subgroup.Bold words within a definition indicate terms that are defined elsewhere in this part of BS 6100, other parts of BS 6100 or other standards. Reference to where the term is defined is given in parenthesis after the bold word.NOTE 1 References to terms defined in BS 6100-1 are shown giving
19、only the part number, e.g. (01); references to terms defined in all other parts of BS 6100 are shown using their full reference number, e.g. (07 59005).NOTE 2 Where more than one definition source could be referred to, the reference containing the definition of most general applicability is given.BS
20、 6100-8:20072 BSI 2007Alternative terms are given in medium type below preferred terms which are given in bold type. All alternative terms have the status of being deprecated. Abbreviations are given in bold type below the terms to which they relate.In the vocabulary, terms of more than one word are
21、 written in their natural word order, e.g. pedestal elbow, and the word order is not inverted, e.g. elbow, pedestal. However, inverted forms of a term are included in the index in BS 6100-0.Terms are only given in the singular form, even when the plural form is more common (unless the term is only f
22、ound in the plural form). 3 Timber (08 1xxxx)3.1 Materials (08 13xxx)08 13001 standing timberstanding trees (06 12036) suitable for conversion (BS 4261)08 13006 structural timbertimber (01) used in frames (01) and structures (01) where strength (11 27007) is the major factor in its selection and use
