11、(c) BSI BS 5325:1996 BSI 02-1999iii Foreword This British Standard has been prepared by Technical Committee TCI/3 as a revision of BS 5325:1983, which is withdrawn. The main changes from the 1983 edition are that: the development of European Standards for the floor covering materials involved is rec
12、ognized; 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 British Standard does not purport to incl
13、ude 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 front cover, an inside front cover, pages
14、 i to iv, pages 1 to 28, 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: sheffieldun sheffieldun, na, Mon Dec 04 14:20:34 GMT+0

General 1.1 Scope This British Standard gives recommendations for the installation of textile floor coverings
16、. It covers all products composed of textile material with a pile or non-pile use surface, and includes the laying of carpet tiles, either with the use of a permanent adhesive or a tackifier. It details suitable methods of installation and advises on the selection of the materials required for their
17、 implementation. Section 2 briefly describes the textile floor covering materials and the associated materials which may be used in their installation. It gives cross references to other British Standards where full details of the materials and their use can be found. Section 3 provides information
18、on the matters which need to be considered prior to the actual installation of the textile floor covering. Some of the points raised may need attention and rectification by the installation contractor, others may need work by other contractors. Section 4 deals with the installation of textile floor
19、coverings in both domestic and commercial areas. The methods which should be used for the various types of textile floor coverings are detailed and are also related to the areas where they may be used. The completely unattached laying (loose-lay) of squares, rags, runners, tiles, etc. is not include
20、d. 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 publications are listed on the inside back cover. For dated refe
21、rences, 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 the cited publication applies, together with any a
22、mendments. 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 standard are listed on the inside back cover, but reference should be made to the latest editions. 1.3
23、Definitions For the purposes of this standard, the following definitions apply. 1.3.1 carpet underlay a coherent layer of textile or other material placed beneath an exposed floor covering NOTEIt may be fibrous, non-fibrous or combined. It provides underfoot comfort and energy absorbing properties (
24、see BS 5808). 1.3.2 fabricated underlay manufactured board made from wood, wood particles or wood fibres in sheet form, usually laid over solid timber floors, to provide a suitable surface to receive the specified textile floor covering 1.3.3 in situ underlay a layer of compacted material, applied i
25、n situ to a sound base or screed where there is a need to raise the level of the floor surface, or to level a floor that is out of true NOTEAn in situ underlay is used where a conventional sand/cement screed is considered unsuitable due to thickness or other limitations. 1.3.4 interlay a thin flexib
26、le sheet, approximately 0.5 mm to 1.0 mm thick, comprised of or manufactured from textile material which is placed below the carpet underlay or textile floor covering 1.3.5 screed a layer of well compacted material, commonly a mixture of cement and aggregate, applied in situ to a concrete base at th
27、e appropriate thickness NOTEThe appropriate thicknesses are given in BS 8204. The screed should be suitably finished to receive the interlay, underlay, or textile floor coverings to be applied, and to enable the textile floor covering to be laid to the designated level. 1.3.6 smoothing underlayment
28、a thin layer of compacted material, applied in situ to a sound base, screed or underlay to provide a smooth finish prior to laying the interlay, carpet underlay or textile floor covering Licensed Copy: sheffieldun sheffieldun, na, Mon Dec 04 14:20:34 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 532
29、5:1996 2 BSI 02-1999 1.3.7 tackifier a peelable, pressure sensitive adhesive normally allowed to dry, i.e. become tacky, before the floor covering is installed NOTEThis definition, which is used by the textile floor covering industry, differs from that adopted by the adhesives industry and given in
30、EN 9231) 1.3.8 textile floor covering a product having a use-surface composed of textile material and generally used for covering floors NOTEIn this British Standard the term “textile floor covering” is used throughout to denote a textile product that is partially adhered/fixed or fully adhered/fixe
31、d, either permanently or temporarily, to the floor. 1) In preparation. Licensed Copy: sheffieldun sheffieldun, na, Mon Dec 04 14:20:34 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 5325:1996 BSI 02-19993 Section 2. Materials 2.1 Fabricated underlays Fabricated underlays should be selected from the f
32、ollowing: a) plywood conforming to BS 6566-4 to BS 6566-6 NOTEA European Standard is under development together with a number of other standards on plywood and when these have been published BS 6566 will be withdrawn. b) particleboard conforming to BS 5669-2 (see 3.6.3). The board should not have an
33、y surface treatment which might affect adhesion; c) fibreboard conforming to BS 1142 (see 3.6.4). 2.2 In situ underlays In situ underlays should be selected from the following: a) mastic asphalt conforming to grade 1 of BS 6925; b) cementitious underlay consisting of a specially formulated blend of
34、cement and binder and both fine and coarse aggregates. The binder is commonly a natural rubber latex or synthetic polymer. 2.3 Underlayments Underlayments should be selected from the following: a) cementitious underlayment consisting of a specially formulated blend of cement, binder and fine aggrega
35、te. The binder is commonly a natural rubber or synthetic polymer dispersion; b) powder/water mixes based on casein/cement or polymer/cement and fine aggregate; c) epoxy or other resin compounds. 2.4 Interlays Interlays are supplied in the following types: a) dry felt paper, manufactured as a thin, f
36、lexible sheet, approximately 0.5 mm to 1 mm thick. b) sheet manufactured from lightweight melded textile material; c) sheet manufactured from spun-bonded fibres; d) release or delaminatable interlays. 2.5 Carpet underlays Carpet underlays are defined, described and classified in BS 5808. They may be
37、 used with all textile floor coverings, except where a foam, solid polymeric or felt backing is an integral part of the floor covering. 2.6 Textile floor coverings Textile floor coverings may be divided into the following two groups. a) woven; b) non-woven. Either of these may be given one of a vari
38、ety of backing treatments which require specific methods of installation. For details of the types of construction which are available see BS 5557. For assistance on the selection of textile floor coverings for various use areas reference should be made to BS 7131-1. NOTEEuropean Standards which des
39、cribe European classification systems are currently in preparation. If these standards are ratified by CEN they will be implemented in the UK, and BS 7131-1 will be withdrawn. 2.7 Adhesives 2.7.1 General The types of adhesive suitable for laying textile floor coverings, with or without an underlay,
40、when this method is indicated, are classified in BS 5442-1. The choice of adhesive will be influenced by the nature of the textile floor covering being installed and by the subfloor. The recommendations of the textile floor covering manufacturer should be taken into account, and followed precisely i
41、f they are specific as to the type of adhesive which should be used. When the textile floor covering is being laid by a method involving total adhesion to the substrate, either alone or with a carpet underlay, the adhesives used should be compatible with both the materials used in the system and the
42、 substrate. None of the adhesives can be considered effective as a damp-proof membrane. 2.7.2 Use of adhesive The suitability of laying various types of textile floor covering using different systems of adhesion are set out in 4.9 and Table 1. Adhesives containing hydrocarbon solvents are not suitab
43、le for use with mastic asphalt substrates. In general, adhesives based on aqueous emulsions are not suitable for use on an impermeable substrate unless it has been first overlaid with a latex/cement screed. Reference should be made to 4.13, where the subject of plasticizer migration is covered in so
44、me detail.

45、d safely and without risk to health. It also requires that users ensure that they have the relevant information and follow the recommendations given. In order to comply with the latter requirement it is essential that the product manufacturers instructions and data sheets are consulted and the recom
46、mendations implemented when any form of adhesive is being used. The Control of Substances Hazardous to Health (COSHH) Regulations 2 require that all work involving hazardous substances, which will include some types of adhesive, be examined to assess the risk to personnel, that the risk is eliminate
47、d or adequately controlled and that controls are monitored to ensure that they are effective. Where hot water pipes are laid below the flooring for purposes other than heating they can raise the temperature of the subfloor. High temperatures may also be caused by direct sunlight falling on the texti
48、le floor covering when buildings have large windows with southerly aspects. In these circumstances any adhesives used should be capable of withstanding the temperature produced. 2.7.3 Forms of adhesive Spreading of liquid adhesives is normally by applicator roller, spreader or notched trowel. In the
49、 last instance, reference should be made to the adhesive manufacturers instructions regarding the size and number of notches in relation to the applied weight of adhesive appropriate to the installation. In addition to fixing with liquid adhesives, textile floor coverings may be fixed by the use of double-sided tapes which are normally of the self adhesive type (see 4.9.2.6). 2.8 Edging and dividing strips Edging and dividing strips are available in wood, metal and plastics. These may be used between similar or dissimilar types, thicknesses, or colours of text
