The work of preparing Inte
10、rnational Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison wi
11、th ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directive
12、s, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some o
13、f the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declaratio

16、1 Scope This International Standard sets out the requirements for installing textile floor coverings (carpets). It gives details of the work necessary in preparing subfloor surfaces together with the procedures that are to be adopted where textile floor coverings are laid over various types of subfl
17、oors and underlays and where subfloor heating units are installed. NOTE This International Standard addresses needle insertion tufted, woven, fusion bonded, fibre bonded, knitted, non-woven, felted, and flocked textile floor coverings. The objective of this International Standard is to provide the c
18、ontractors, manufacturers, suppliers, and purchasers of textile floor coverings and others, for example, technical educators, with procedures to enable the provision of correctly installed textile floor coverings. 2 Normative references The following documents, in whole or in part, are normatively r

Where applicable, the textile floor covering referred to in this International Standard shall be suitable for use above subfloor heating wh
37、ere the temperature of the upper surface of the subfloor does not exceed 29 C. 4.2 Underlays 4.2.1 Underlays Unless the subfloor is substantially free from grooves, ridges, gaps, holes, and similar imperfections, the use of a hard underlay is recommended. ISO 2014 All rights reserved 3 ISO/PAS 18167
38、:2014(E) Where a hard underlay is used, the following requirements apply: a) the underlay shall have an estimated service life not shorter than that of the textile floor covering; b) the underlay shall be compatible with the textile floor covering and the adhesive(s) to be used; c) the underlay shal
39、l be non-staining, non-exuding, and sufficiently dense to withstand normal traffic load on the floor without becoming indented or deformed; d) the underlay shall be capable of being bonded to the subfloor in such a manner that the bonding is not affected by normal traffic loading; e) the underlay sh
40、all be non-shrinking to the extent that when the textile floor covering is laid, no evidence of gaps shall be visible; f) the maximum variation in length between the diagonals of underlay sheet shall not exceed 1,0 mm; g) for timber subfloors, the underlay shall be either reduced density hardboard f
41、looring underlay or medium density fibreboard or medium density fibre cement sheet known to manufacturers as hard underlay. NOTE Other products can be used if agreed between the contractor and the purchaser. 4.2.2 Soft underlays The soft underlay shall have a service life no shorter than that of the
42、 textile floor covering in accordance with the recommendations of the underlay manufacturer and the carpet manufacturer. The requirements for soft underlays are detailed in Annex E of this International Standard. In commercial applications, soft underlays shall have a total thickness not greater tha
43、n 10 mm. For installation of soft underlays, see 6.7 and 6.8. Carpet should never be laid over existing carpet and/or existing underlay as this can cause permanent damage to the new floor covering installation. 4.3 Adhesives The choice of adhesives shall be made by consultation between the contracto
44、r and the manufacturer/supplier of the selected underlay, manufacturer/supplier of the textile floor covering, and the manufacturer/supplier of the adhesive and the purchaser shall be advised if requested. Adhesives used shall be such that they ensure minimal hazardous risk to both personnel and pro
45、perty involved with the installation and site. Adhesives used shall be labelled in accordance with the regulations concerning occupational health and safety, poisons, dangerous goods, and transportation of dangerous goods. Material Safety Data Sheets which should be easily obtainable from manufactur
46、ers of all chemical products should be provided on-site whenever adhesives are being used. Where the relative humidity of the atmosphere in the building is 75 % or more, only adhesives suitable for such conditions shall be used. Any such adhesive shall be used in accordance with the instructions of
47、the manufacturers of the textile floor covering and of the adhesive. NOTE 1 In high humidity, condensation can form on the surface of the substrate and/or adhesive and prevent adhesion of the flooring. Where subfloor heating units are installed, the adhesive shall be such that it is not affected adv
48、ersely by the temperature at which the heating units are to be operated.4 ISO 2014 All rights reserved ISO/PAS 18167:2014(E) Where additives such as curing agents, parting agents, and surface treatments which can have a deleterious effect on an adhesive are present on the subfloor, the adhesive shal
49、l be isolated from the deleterious material/s with the use of appropriate trowelled-on compounds. NOTE 2 Some curing agents might need to be removed by grinding or sanding. Some parting agents can be removed by washing with sugar soap, water blasting, and/or grinding. 4.4 Carpet gripper The carpet gripper shall be constructed of five even thickness plywood layers. The carpet gripper shall be constructed of sufficient pins and nails so as to withstand a minimum stretching force of 6 580 N over a 1 220 mm length. 5 Pre-Installation
