Introduction
European Standards are currently available for:
• many of the floor covering types on the market in Europe;
• classification schemes, which define the characteristics of a location where a floor covering is to be used,
and enable an appropriate product to be selected
For these products to give satisfactory service, they need to be installed competently, in accordance with the
manufacturer’s instructions, with the appropriate national code of practice for textile floor covering or following
the advice of this part of the Technical Specification. It is also important that they receive appropriate
maintenance in service according to the manufacturer's instructions.

1 Scope
This Technical Specification provides recommendations for the installation of textile floor coverings. It covers
all products composed of textile material with a pile or non-pile use surface, and includes the laying of carpet
tiles (excluding rugs). It details suitable methods of installation and advises on the selection of the materials
required for their implementation.
The guidelines in this Technical Specification are intended for use in cases where manufacturer's instructions,
taking account of the national code of practice in the country where the installation is to be made, are not
available. References to the national codes that are currently available are listed in the bibliography of the
various parts of this Technical Specification.
This Part 2 of the Technical Specification is intended for use in conjunction with Part 1 that deals with general
matters relevant to resilient and laminate floor coverings as well as textile floor coverings.
All parts of the Technical Specification are intended to supplement and not conflict with national standards.
2 Normative references
This Technical Specification incorporates by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text, and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to
this Technical Specification only when incorporated in it by amendment or revision. For undated references
the latest edition of the publication referred to applies (including amendments).
CEN/TS 14472-1:2003 Resilient, textile and laminate floor coverings – Design, preparation and installation
– Part 1: general.
ISO 2424 Textile floor coverings – Vocabulary.
3 Terms and definitions
For the purposes of this Technical Specification 14472, the terms and definitions given in ISO 2424 and in
CEN/TS 14472-1 apply together with the following:
3.1
underlayment
thin layer, applied to a screed to provide a smooth and/or flat surface to receive the floor covering.
3.2
interlay
thin flexible sheet, supplied in 1-2 meter wide rolls. This interlay 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.
3.3
carpet underlay
coherent layer of textile or other material placed beneath an exposed floor covering.

NOTE It can be fibrous, non-fibrous or combined. It provides underfoot comfort, sound absorbing and energy
absorbing properties. (A standard that specifies minimum requirements for carpet underlays is currently being prepared
by CEN/TC 134).
3.4
electrostatic discharge sensitive device (ESDS)
discrete device, integrated circuit or assembly that may be damaged by electrostatic fields or electrostatic
discharge encountered in routine handling, testing or transit (IEC 61340-5-1)
3.5
electrostatic protected area (EPA)
area in which an ESDS can be handled with accepted risk of damage as a result of electrostatic discharge or
fields ( IEC 61340-5-1)
3.6
crotch (of stair-tread)
junction of the lower edge of the riser with the rearmost edge
3.7
shading
general description given to a number of optical effects in the appearance of textile floor coverings due to
localised alterations in the orientation of the fibres, tufts or loops. 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, at the right time, etc, it is
essential 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 sub-contractors and materials
suppliers. This consultation should start early in the design stage but will be necessary throughout 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
typical examples, applying to textile floor coverings as well as to resilient and laminate floor coverings are
given in CEN/TS 14472-1.
4.2 Shading
"Shading" (see 3.7) can not be attributed to a fault of manufacture or installation, but architects and specifiers
should be aware of this phenomenon in certain styles of carpets.
5 Materials
5.1 Underlayments
Underlayments may be selected from the following:
a) cementitious underlayment consisting of a specially formulated blend of cement, binder and fine
aggregate. 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;
6

---------------------- Page: 8 ----------------------

SIST-TS CEN/TS 14472-2:2003
CEN/TS 14472-2:2003 (E)
c) epoxy or other resin compounds (e.g. primer);
d) compatible underlayments that are available for direct contact with an anhydrite screed.
5.2 Interlays
Interlays may be of the following types:
a) dry felt paper, manufactured as a thin, flexible sheet, approximately 0,5 mm to 1,0 mm thick;
b) sheet manufactured from lightweight melded textile material;
c) sheet manufactured from spun-bonded fibres;
d) release or delaminateable interlays.
5.3 Carpet underlays
Carpet underlays are defined, described and classified in BS 5808 and work on developing a standard for
minimum requirements is in progress in CEN/TC 134. They usually improve the walking comfort, impact
sound insulation, thermal insulation, carpet life and smoothing minor surface irregularities of subfloors.
5.4 Textile floor coverings
Different types of floor coverings may require specific methods of installation (see Table 1).
For details of the types of construction, which are available, see ISO 2424. For assistance on the selection of
textile floor coverings for various use areas reference should be made to EN 1307, EN 1470 and EN 13297.
5.5 Adhesives
5.5.1 General
The adhesive selected should be considered at the design stage because it can influence the performance
during installation, in use, or later during removal. The recommendations of the textile floor covering
manufacturer should be taken into account, and followed precisely if they are specific as to the type of
adhesive which should be used.
Adhesives may be used to enable carpet tiles to be moved without damage, using a semi-permanent or
tackifier adhesive, or for the permanent installation of the floor covering. When the textile floor covering is
being laid by a method involving total adhesion to the substrate, alone, with a carpet underlay or in a
strippable system, the adhesives used should be compatible with both the materials used in the system and
the substrate.
Low emission adhesives may be used to meet requirements for internal air quality, during installation or in
service.
In addition to installation with liquid adhesives, textile floor coverings may be fixed by the use of double-sided
tapes which are normally of the self adhesive type and release systems (net) etc.
Fabric reinforced hot melt tapes can be used for joining or seaming certain types of carpet suitable for
installation on grippers.
None of the adhesives can be considered effective as a damp-proof membrane.

5.5.2 Use of adhesive
Recommendations on the suitability of laying various types of textile floor covering using different systems of
adhesion are given in 7.8 and Table 1.
A health and safety risk assessment should be made before using any adhesive. Any special requirements
such as ventilation, limited access or other appropriate action to protect either the installer or those individually
involved should be agreed with the main contractor before installation
The adhesive manufacturer’s instructions for the use of the adhesive should be followed, with particular
emphasis on the application tool, e.g. notch trowel (including the correct size, shape and number of notches)
or roller, or heated iron, the coverage rate and any follow on process, rolling etc.
Conductive adhesives are available for static sensitive areas. These contain carbon black metalised fibres or
particles.
6 Subflooors
6.1 General
New subfloors should be constructed in accordance with the recommendations given in the relevant national
or European standards.
Those responsible for the design and construction of the subfloor should ensure that it meets the
requirements, i.e. should ensure that it has the necessary characteristics to allow the floor covering to be
installed successfully before the installer of the floor covering is asked to commence work.
These characteristics include:
a) regularity of concrete floors and screeds;
b) moisture content of concrete floors and screeds;
c) integrity of screeds;
d) making-good of cracks;
e) treatment of construction joints;
f) gaps and changes of level;
g) moisture content of wooden subfloors;
h) presence of asbestos in an existing floor covering.
General information and guidance on subfloors is given in CEN/TS 14472-1 under the following headings:
 - materials;
 - details concerning concrete and screed bases;
 - moisture content of the subfloor;
 - timber bases;
 - levelling layer and underlayments;
 - existing floor covering.

Figure 1 — Layers of subfloor beneath floor coverings
The information on moisture content of the subfloor together with guidance on damp-proofing and eliminating
construction moisture is particularly important.
The following subclauses provide additional information and guidance on subfloors of particular relevance to
textile floor coverings.
6.2 Board and strip floors
Where plain edged boards or tongued and grooved boards have been nailed to joists or battens, the use of
one of the fabricated substrates listed in 6.7 is essential. This will act as a buffer and thereby help to minimize
movement in the boards which might affect the appearance of the floor covering.
Uneven timber floors should be levelled by sanding, planing or by patch-filling with a suitable cement
underlayment before fabricated underlays are laid. Boarded floors nailed into joists secured by clips set in

---------------------- Page: 11 ----------------------

SIST-TS CEN/TS 14472-2:2003
CEN/TS 14472-2:2003 (E)
concrete or dovetailed battens set in concrete, or boards nailed direct into concrete at ground level should be
adequately ventilated and protected by a damp-proof membrane.
6.3 Wood blocks
The laying of textile floor coverings over bases of wood blocks may lead to problems. Any installation should
not be attempted unless the wood blocks conform to the following :
• the surface of the wood blocks is clean and free from wax;
• the condition of the floor is such that the blocks are sound and firmly bonded;
• the wood blocks are adequately protected against moisture.
If the textile floor covering is to be totally adhered, consideration should be given to the possibility that the
blocks could lift from the subfloor during the life of the floor covering and also when the floor covering is lifted
for renewal.
The fixing of fabricated substrates listed in 5.2.1 of CEN/TS 14472-1:2003 may help to provide a smooth level
surface. However, it is often found that the action of installing the underlay causes the blocks to fracture, or
the wood block adhesive to fail, particularly if it is embrittled by age. Because of the problems, serious
consideration should be given to the removal of the wood blocks and repair of the base prior to installation of
the textile floor coverings. If any doubts exist regarding any of the conditions set out above, the wood blocks
should be removed and the floor screeded or a mastic asphalt floor laid to produce a damp proof membrane.
6.4 Particleboard bases
6.4.1 General
General information and guidance on particleboard bases is given inCEN/TS 14472-1.
6.4.2 Particleboard floating floors
It is permissible to sand off any differences in level between adjacent panels up to 1mm. Above this value
additional levelling materials should be used.
6.5 Raised floor panels
Raised floor panels may have a textile floor finish permanently bonded on before installation of the panels. In
this case the floor covering is generally supplied oversize and then trimmed down to the panel size after the
adhesive has fully set.
For carpet tiles installed after the raised floor is in place, the following are examples of the most used
methods.
EXAMPLE 1 Carpet tiles installed by the use of a release adhesive (tackifier) either applied directly to the middle of the
raised floor panel or to the back of the carpet tile by the use of a brush or paint roller. Care needs to be taken to avoid
adhesive going between the gaps in adjacent panels, which can lead to floor panels being difficult to lift without damage.
EXAMPLE 2 Carpet tiles installed by locating devices on the carpet tiles and panel such as pin and socket, hook and
loop strips or magnetic strips on the back of the tile in the case of steel surfaced raised panel.
It should be noted that even with 600 mm x 600 mm panels and 600 mm x 600 mm carpet tiles it is
impossible to keep in bond due to different manufacturing tolerances (and differing, thermal changes) between
textile carpet tiles and raised floor panels.

---------------------- Page: 12 ----------------------

SIST-TS CEN/TS 14472-2:2003
CEN/TS 14472-2:2003 (E)
Carpet tiles laid across the joints between the raised access floor panels will assist in preventing dust
contamination.
6.6 Other bases
Some existing bases such as clay tiles, concrete tiles or terrazzo are unaffected by dampness, but may be
sufficiently permeable to allow moisture to pass through to the back of the floor covering. These bases, which
should be otherwise sound, should be damp-proofed when necessary by covering with a surface damp-proof
membrane. Joints between tiles may cause problems with thin surface damp-proof membranes.
Existing bases on polyvinyl acetate/cement, gypsum based screeds (anhydrite screeds), magnesium oxy
chloride and wood blocks, are adversely affected by dampness rising through concrete from the ground and
should not be covered with a damp-proof layer or with relatively impervious floor coverings. Unless it can be
established that there is an affective damp-proof course below these materials, they should be removed.
Existing floor coverings and sufficient residual adhesive should be removed and the necessary actions should
be taken to enable the subfloor to receive the floor covering. The dryness of the base with regard to both
moisture from the ground and residual moisture should be in accordance with the recommendations of 5.4 of
CEN/TS 14472-1:2003.
6.7 Fabricated substrates
6.7.1 General
Fabricated substrates should be laid where required over existing bases. They should be chosen taking into
account the prevailing moisture conditions.
NOTE Fabricated substrates are hygroscopic and expand on absorbing moisture. If the moisture content of the
material is in equilibrium with the surrounding air there will be no further movement of the board. In centrally heated
buildings, with a low moisture content, the boards will reach equilibrium by exposure to the surrounding air. However for
hardboard, in damp buildings or new constructions, conditioning by water application is preferable.
6.7.2 Plywood
Plywood should be at least 4 mm thick and with a density of not less than 450 kg/m³. Where, due to the
irregularity of the base, improved rigidity is required, the use of 6 mm or thicker material should be considered.
6.7.3 Particleboard
Particleboard should have a density of not less than 650 kg/m³ or be at least 9 mm thick and free from surface
sealers such as wax, polyurethane or other types of seal and contaminants.
Tongued and grooved joints should be glued with a wood grade polyvinyl acetate adhesive (see 5.5.2 in
CEN/TS 14472-1:2003).
All particleboards should be primed as recommended by the adhesive manufacturer.
6.7.4 Fibreboards
Hardboards, at least 3 mm thick or medium density fibreboard (MDF) at least 3 mm thick are recommended.
Where, due to the irregularity of the base, improved rigidity is required, the use of material greater than 3 mm
should be considered.
Fibreboards have a very strong water absorptive power and are not recommended for use in commercial
areas.

CEN/TS 14472-2:2003 (E)
6.7.5 Gypsum boards
Gypsum boards with different thickness (up to 40 mm) can be used for rapid setup of dry floors in renovating
or refurbishing of old buildings as well as for new buildings.
Irregularities of the floor can be treated by levelling layers up to 15 mm, by wooden joists or by patch filling
with a suitable and manufacturer recommended patch filler. The boards are usually glued together.
This type of floor can only be used in areas with low humidity and because of low heat resistance also on
under floor heating systems. Manufacturers' recommendations should be strictly followed.
6.8 Interlays
Interlays should be used to help in the elimination of contamination from dust migrating through irregular or
gapped floorboards. Interlays will not prevent the transfer of floor irregularities to the materials laid over them
and they should not be used for this purpose.
Interlays should not be used in conjunction with a carpet underlay system where the underlay is adhered to
the floor and the textile floor covering subsequently totally adhered to the underlay.
