20、s For the purposes of this British Standard the following terms and definitions apply. 3.1 fabricated underlay fabricated substrate (non-preferred) manufactured board made from wood, wood particles or wood fibres in panel form, or calcium sulfate (gypsum), to provide a suitable surface to receive th
21、e specified floor covering 3.2 screed layer of well-compacted material, commonly a mixture of cement and aggregate, applied in situ to a concrete base 3.3 mastic asphalt mixture of bitumen and an inert mineral aggregate 3.4 impregnation treatment of a base or a screed by application of a liquid prod
22、uct intended to penetrate the pores without forming a continuous layer on the surface 3.5 levelling layer layer applied to compensate for unevenness and differences in height in the base, to accommodate services, or to give a uniform absorbency where water-based adhesives are to be used 3.6 flowing
23、screed in situ applied material that sets hydraulically or by chemical cure NOTE This is normally a proprietary compound to be used in accordance with manufacturers recommendations. It is poured or pumped directly to the concrete slab to form a smooth level surface, ready to receive most floor cover
24、ings. 3.7 anhydrite screed formulated flowing screed based on hydraulically setting calcium sulfate 3.8 underlayment thin layer applied to a screed to provide a smooth and/or flat surface to receive the floor covering 3.9 interlay thin flexible sheet, supplied in 1 m to 2 m wide rolls NOTE This inte
25、rlay is laid below foam backed carpets to facilitate easy removal and to stop foam adhesion to the subfloor. Dust and other subfloor contamination are stopped from being transferred onto the underfelt or floor covering. The interlay gives enhanced thermal insulation properties to the floor covering.
26、 3.10 carpet underlay a coherent layer of textile or other material placed beneath an exposed floor covering NOTE 1 It may be fibrous, non-fibrous or combined. It provides underfoot comfort, sound absorbing and energy absorbing properties. 3.11 electrostatic discharge sensitive device ESDS a discret
27、e device, integrated circuit or assembly that may be damaged by electrostatic fields or electrostatic discharge encountered in routine handing, testing or transit IEC/TS 61340-5-1BS 5325:2001 BSI 17 December 2001 3 3.12 electrostatic protected area EPA area in which an ESDS can be handled with accep
28、ted risk of damage as a result of electrostatic discharge or fields IEC/TS 61340-5-1 3.13 crotch junction of the lower edge of the riser with the rearmost edge of a stair-tread 3.14 shading general description given to a number of optical effects in the appearance of textile floor coverings due to l
29、ocalized alterations in the orientation of the fibres, tufts or loops NOTE This is not a real change in hue, but a difference in light reflection. 4 Exchange of information 4.1 General In order for the correct floor covering to be installed in appropriate conditions, and at the right time, it is ess
30、ential that all parties have a clear understanding of the requirements of the project, e.g. new build or 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 s
31、ubcontractors and materials suppliers. This consultation should start early in the design stage but should continue throughout the contract, especially if 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 definitiv
32、e list of the information to be exchanged, but 4.2 to 4.9 give typical examples. 4.2 Project The name and location of projects and personnel involved in pre-contract negotiations should be identified. 4.3 Contract conditions A programme for commencement and completion of work should be defined, incl
33、uding any specific requirement for sequenced completion. 4.4 Special attendance Access, unloading, hoisting and storage facilities, heat, light and power and any additional items considered necessary to expedite the work should be provided. 4.5 Design 4.5.1 General The flooring layout and specificat
34、ions, based on building type and occupational uses, should be provided, for example: a) type of use building, rooms; b) type and density of foot and/or wheeled traffic; c) specific requirements: fire resistance period, acoustic absorption level, slip resistance; d) particulars of use staining, poten
35、tially abrasive conditions.BS 5325:2001 4 BSI 17 December 2001 4.5.2 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 suspended construction; c) particulars of an
36、y underfloor 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 level, permissible departure from datum a
37、nd 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 a surface applied membrane where likel
38、y drying times for the base exceed the time available in the programme; i) choice of substrate, underlayment, adhesives, intermediate products and floor coverings; j) requirements for jointing, e.g. seam welding, direction of material and position of seams; or the position and type of expansion join
39、ts profiles; k) size, position and design of entrance flooring systems (see BS 7953). 4.5.3 Entrance zone The size, position and design of the entrance zone should be considered at the design stage, in accordance with BS 7953. NOTE Entrance flooring systems will reduce the dirt, grit and water carri
40、ed into the building by foot traffic, and hence will reduce wear and the risk of slipping when the building is in service. 4.5.4 Associated details Details of abutments, skirtings, services (embedded or sleeved), movement joints, separating strips, pattern or border details and junction with other a
41、djacent flooring should be provided. 4.5.5 Shading “Shading” (see 3.14) cannot usually be attributed to a fault of manufacture or installation, but architects and specifiers should be aware of this phenomenon in certain styles of carpets. 4.6 Testing Details of any conformity testing of the base, sc
42、reed and floor covering that is to be conducted, and the party to be responsible for this testing, should be provided. The implications of this also have to be considered in the programme defined in 4.3. For instance, it is essential that the responsibility is defined for ensuring that bases or scre
43、eds meet the specified standards of level, smoothness, dryness and soundness (impact crushing resistance) before any subsequent or finishing trades are called to commence work. NOTE In the case of new-build installations, this will be the responsibility of main contractor. 4.7 Health and safety Arra
44、ngements for liaison and cooperation on health and safety requirements between the different parties in the contract should be established. 4.8 Responsibilities Responsibilities for cleaning the construction on completion and giving it initial protection should be defined.BS 5325:2001 BSI 17 Decembe
45、r 2001 5 4.9 Maintenance The customer should be left with adequate details of the maintenance required to enable the floor covering to perform satisfactorily in use. The recommendations should include details of the various types of cleaning and maintenance needed and the time scales at which they s
46、hould be carried out. NOTE It is preferable that such instructions be in clear, written form, and cover the recommended maintenance methods appropriate for all the types of floor coverings installed. 5 Materials 5.1 Fabricated underlays (see also 6.6) Fabricated underlays may be selected from the fo
47、llowing: a) plywood conforming to BS EN 636-1; b) particle board Type P2 conforming to BS EN 312-2:1997, or if improved bending strength and stiffness are required, Type P4 conforming to BS EN 312-4:1997 (see 6.7.3 of this standard); c) fibreboard: hardboard Type HB conforming to BS EN 622-2:1997, h
48、igh density medium board Type MBH conforming to BS EN 622-4:1997 and medium density fibreboard Type MDF conforming to BS EN 622-5:1997 (see 6.7.4 of this standard); d) gypsum board; e) others. The strength and construction of the fabricated underlay should be such that it is able to function in use
49、without swelling, shrinkage, delamination or disintegration. 5.2 Cementitious based substrates (levelling layer) A levelling layer should be used where a conventional cement-sand screed is considered unsuitable because of thickness or other limitations. The levelling layer may be a cementitious underlay consisting of a specially formulated blend of cement and binder and both fine and coarse aggregates. NOTE The binder is commonly a natural rubber latex or synthetic polymer. 5.3 Anhydrite screed It is recommended t
