It is a revision of BS 8203:1996 which is withdrawn. As a code of pra
9、ctice, this British Standard takes the form of guidance and recommendations. It should not be quoted as if it were a specification and particular care should be taken to ensure that claims of compliance are not misleading. A British Standard does not purport to include all the necessary provisions o
10、f a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 22, an insid
11、e back cover and a back cover. The BSI copyright notice displayed in this document indicates when the document was last issued. BS 8203:2001 BSI 01-2001 1 Section 1. General1 1.1 Scope This British Standard gives recommendations for the installation of the following floor coverings on both new and e
12、xisting constructions: a) cork floor coverings; b) linoleum floor coverings; c) plastics floor coverings; d) rubber floor coverings. Special measures are necessary for successful installation of floor coverings such as those used for static control, and are not included in this standard. This Britis
13、h Standard does not cover the installation of these floor coverings on access flooring. This British Standard does not include advice on cleaning and maintenance (which is given in BS 6263-2) but it does include guidance on the decisions which should be made at the design stage which will assist cle
14、aning and maintenance and enable the installation to give satisfactory service. 1.2 References 1.2.1 Normative references This British Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are made at the appropriate places in the text a
15、nd the cited publications are listed on page 21. For dated references, only the edition cited applies; any subsequent amendments to or revisions of the cited publication apply to this British Standard only when incorporated in the reference by amendment or revision. For undated references, the lates
16、t edition of the cited publication applies, together with any amendments. 1.2.2 Informative references This British Standard refers to other publications that provide information or guidance. Editions of these publications current at the time of issue of this British Standard are listed on page 22,
17、but reference should be made to the latest editions. 1.3 Definitions For the purposes of this British Standard the definitions in BS 6100 and the following definitions apply. 1.3.1 agglomerated composition cork a compound of cork granules with a binder generally not derived from cork cells 1.3.2 agg

36、r refurbishment, and of the implications for all concerned. To ensure that this is achieved, it is essential that there is wide consultation between all parties involved in the project, including sub-contractors and materials suppliers. This consultation should start early in the design stage but wi
37、ll be necessary throughout the contract, especially should requirements or time scales change and as new sub-contract work is initiated. As each project will be unique it is impossible to give a definitive list of the information to be exchanged, but the following are typical examples. 1.4.2 Project
38、 The name and location of projects and personnel involved in pre-contract negotiations should be identified. 1.4.3 Design The flooring layout, and specifications, based on building type and occupational uses should be provided, e.g.: a) type and density of foot and/or wheeled traffic; b) resilience
39、characteristics; c) acoustic absorption levels; d) particulars of wet, corrosive, staining or potentially abrasive conditions. 1.4.4 Floor details The completed drawings/specification should provide comprehensive information on: a) whether upper floor, ground floor or below ground level; b) whether
40、ground-supported or suspended construction; c) particulars of any under floor heating installation or security installation; d) position and treatment of expansion joints; e) curing and drying times of screeds and bases likely to be required before the installation of floor coverings; f) screed or b
41、ase with finished floor level, permissible departure from datum and class of surface regularity required; g) in refurbishment work, the type and condition of existing base or floor finish and any type of treatment required; h) type of damp-proof membrane and position within the floor construction, i
42、n particular, the need for surface applied membrane where likely drying times for the base exceed time available in the programme; i) choice of underlay, underlayments and adhesives, or special requirements, e.g. seam welding and direction of material; j) size, position and design of entrance floori
43、ng systems. 1.4.5 Entrance flooring systems Entrance flooring systems will reduce the dirt, grit and water carried into the building by foot traffic, hence will reduce wear and the risk of slipping when the building is in service. The size, position and design of entrance flooring systems should be
44、considered at the design stage (see BS 7953). BS 8203:2001 4 BSI 01-2001 Section 1 1.4.6 Associated details Details of abutments, skirtings, services (embedded or sleeved), movement joints, separating strips, pattern or border details and junctions with other adjacent flooring and door clearances sh
45、ould be provided. 1.4.7 Contract conditions A programme for commencement and completion of work should be defined, including any specific requirement for sequenced completion see especially 1.4.4e). 1.4.8 Special attendance Access, unloading, hoisting and storage facilities, heat, light and power an
46、d any additional items considered necessary to expedite the work should be provided. 1.4.9 Testing For any conformity testing of the base, screed, floor covering, etc. details should be provided and responsibilities defined. For instance, it is essential that the responsibility is defined for ensuri
47、ng that bases or screeds meet the specified standards for level, smoothness, dryness and soundness (impact crushing resistance) before any subsequent or finishing trades are called to commence work. In most circumstances this will be the responsibility of the main contractor. 1.4.10 Responsibilities
48、 Responsibilities for cleaning the construction on completion and giving it initial protection should be defined. 1.4.11 Maintenance Clear written instructions on the recommended maintenance methods appropriate for the various floor coverings should be provided for the occupier (see BS 6263-2).
