10、-1999 Foreword This British Standard has been prepared by Technical Committee PRI/60 as a revision of BS 8203:1987, which is withdrawn. The main changes from the 1987 edition are that: the development of European Standards for the floor covering materials involved is recognized; text which was in co
11、mmon with that in BS 8204-1 has been deleted; greater attention is given to the importance of cooperation between the various parties involved prior to, during and after the installation of the floor coverings; annex A on dampness testing has been revised in the light of current developments. A Brit
12、ish Standard does not purport to include all the necessary provisions of 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 fron
13、t cover, an inside front cover, pages i and ii, pages 1 to 20, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover. Licensed Copy: London South Ban

General 1.1 Scope This British Standard gives recommendations for the installation of the following floor coverings on both new and existing const
15、ructions: a) cork floor coverings; b) linoleum floor coverings; c) plastics floor coverings; d) robber 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 British Standard do
16、es 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) but it does include guidance on the decisions which should be made at the design stage which will assist cleaning and maint
17、enance 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 and the cited pu
18、blications are listed on page 18. 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 latest edition of th
19、e 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 the inside back cover, b
20、ut 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 aggl

40、 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 will be necessary throughout
41、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 The name and location of p
42、rojects 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 characteristics; c) acousti
43、c 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 ground-supported or suspend
44、ed 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 base with finished floor lev
45、el, 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, in particular, the need for
46、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 mat wells. 1.4.5 Mat wells Passive dirt bar
47、rier systems at entrances 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 mat wells should be considered at the design stage. 1.4.6 Associated details Det
48、ails of abutments, skirtings, services (embedded or sleeved), movement joints, separating strips, pattern or border details and junction with other adjacent flooring should be provided.
