8、een prepared under the direction of the Adhesive Standards Policy Committee. The standard provides a classification, in terms of usage, of the many types of adhesives available for use in the construction industry. Part 1 deals with adhesives for use with flooring materials, Part 2 deals with adhesi
9、ves for interior wall and ceiling coverings (excluding decorative flexible materials in roll form which are dealt with in BS 3046) and Part 3 deals with adhesives for use with wood. This revision takes account of changes in some of the flooring materials commonly used, and in the methods used to fix
10、 them, since Part 1 was first published in 1977. Two classes of adhesive have been deleted and one added to the table of adhesives and their applications, reflecting current practice. Also, there are now no entries listing the preferred adhesives for cork tiles, since there is no clear view on the s
11、uitability of given types of adhesive. It is suggested that recommendations of the manufacturer of the cork tiles be obtained and followed. This Part supersedes BS 5442-1:1977 which is withdrawn. A British Standard does not purport to include all the necessary provisions of a contract. Users of Brit
12、ish 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 and 2, an inside back cover and a back cov
13、er. 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.

14、19991 1 Scope This Part of BS 5442 classifies the preferred adhesives for laying the different types of flooring materials used in building construction. No suggestion in this standard, as to the materials to be employed in a particular case, is intended to override specific recommendations made by
15、the manufacturer of the flooring material. NOTEThe titles of the publications referred to in this standard are listed on the inside back cover. 2 Classification The necessary information is given in Table 1, which indicates the preferred adhesives for any particular flooring material. With certain f
16、looring materials, several types of adhesive other than those given in the table could be used, but such adhesives are not included if in practice they would usually be avoided in favour of cheaper materials of equal technical suitability. The flooring materials are listed using, wherever possible,
17、the names that appear in the respective British Standards. If no British Standard exists, the usual commercial nomenclature is employed. Flooring materials not covered by British Standards, however, may vary appreciably despite being similarly named, and it is emphasized that the flooring/adhesive c
18、ombination shown in Table 1 gives only a tentative indication in such cases. Unless otherwise agreed between the supplier and the purchaser, the flooring materials shall be laid in accordance with British Standards BS 5325, BS 5385-3, BS 8201 and BS 8203. Unless qualified by footnotes or by the comm
19、ents on specific subfloor types given below, the information in the table applies to the three most common groups of substrates, which are the following: a) cementitious, in-situ underlay, in-situ terrazzo and terrazzo tiles, cement based levelling compositions modified with polymers, rubber latex o
20、r a protein, and synthetic anhydrite screeds; b) timber, including boarded flooring, both plain edged and tongued and grooved boarding, an appropriate flooring grade of wood chipboard complying with BS 5669, standard or tempered hardboard complying with BS 1142-2 and plywood complying with BS 6566-1
21、; c) mastic asphalt complying with the requirements of either BS 6577 or BS 6925. Unless otherwise agreed between the supplier and the purchaser, all the above materials shall be laid or fixed in accordance with CP 102, BS 5385-3, BS 8201, BS 8203 and BS 8204. NOTE 1Some substrates require the stand
22、ard of finish to be improved prior to the laying of the flooring. Recommendations for this are given in BS 5325 and BS 8203 and should be followed. NOTE 2Steel floor surfaces are not commonly used as substrates in normal building construction. The specification to be used in individual cases should
23、be the subject of consultation between the flooring material supplier and the flooring contractor. Key to Table 1 NOTE 1Adhesives containing hydrocarbon solvents are not suitable for use with mastic asphalt substrates. NOTE 2In general, aqueous emulsion based adhesives are not suitable for use on an
24、 impermeable substrate unless it has been first overlaid with a latex/cement screed. 1. Gum spirit. A solution of rosin in alcohol containing filler and possibly other modifiers. 2. Lignin paste. An aqueous dispersion of sulphite lye with fillers. 3. Rubber solution. A solution of natural or synthet
25、ic rubber in organic solvent, containing resinous or other modifiers. 4. Styrene-butadiene rubber (SBR) latex. An aqueous dispersion of styrene-butadiene rubber, which may contain added synthetic resin modifiers and/or fillers. 5. Acrylic emulsion. An acrylate ester copolymer emulsion based either o
26、n acrylic ester co-monomers or an acrylate ester copolymerised with other monomers such as styrene, vinyl acetate etc. It may contain resin modifiers and/or fillers. 6. Bitumen solution. A solution of a blend of bitumens in suitable solvents, with the addition of powdered and/or fibrous mineral fill
27、ers. 7. Bitumen/rubber emulsion. An aqueous emulsion of bitumen of appropriate grade with the addition of natural or synthetic rubber latex. 8. Epoxide resin. Two-component system consisting of liquid epoxide resin and liquid hardener, both of which may contain fillers and which are mixed immediatel
28、y before use. 9. Polyvinyl acetate (PVAC) emulsion. An aqueous emulsion of polyvinyl acetate homopolymers or copolymers, which may contain fillers. 10. Polymer modified cement. A blend of Portland cement and filler gauged with an aqueous dispersion of polyvinyl acetate (PVAC), ethylene vinyl acetate
29、 (EVA), styrenebutadiene rubber (SBR), acrylic resin or natural rubber. 11. Cementitious adhesive. An adhesive based on a cement, e.g. Portland cement, with admixtures, used in accordance with the relevant parts of BS 5385-1.
