Page 4EN 12004:2001IntroductionThe characteristics of the construction products defined in this standard have to consider that the normalstresses due to the works for which they are intended, assembled or installed, can be properlyaccommodated. Some special characteristics will take into account the type of substrate and that theadhesives should resist the degrading actions of climate, etc.Many properties of adhesives for tiling are mainly determined by the type of binders used.Different types of tile adhesives are defined according to the chemical nature of their binders.The different types have specific characteristics in terms of their application properties and finalperformance.The relationship between characteristics and the working conditions (dry or humid conditions, hot climate,fast setting, etc.) is not given in this Standard.The manufacturer should give information about the use of the product and the correct conditions of use.The specifier should evaluate the state of the job site (mechanical and thermal influences) and choose theappropriate product considering all the possible risks.SIST EN 12004:2002



Page 5EN 12004:20011ScopeThis European Standard is applicable to ceramic tile adhesives for internal and external tile installationson walls and floors.This standard gives the terminology concerning the products, working methods, application properties,etc, for ceramic tile adhesives.This European Standard specifies the values of performance requirements for ceramic tileadhesives (cementitious, dispersion and reaction resin adhesives).This European Standard does not provide criteria or recommendations for the design and installation ofceramic tiles.NOTE Ceramic tile adhesives may also be used for other types of tiles (natural andagglomerated stones, etc. ), where these do not adversely affect these materials.2Normative referencesThis European Standard 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 listedhereafter. For dated references subsequent amendments to, or revisions of, any of these publicationsapply to this European Standard only when incorporated in it by amendment or revision. For undatedreferences the latest edition of the publication referred to applies (including amendments).EN 87Ceramic floor and wall tiles – Definitions, classification and markingEN 1308Adhesives for tiles - Determination of slipEN 1324:1996Adhesives for tiles - Determination of shear adhesion strength of dispersion adhesivesEN 1346Adhesives for tiles - Determination of open timeEN 1347Adhesives for tiles - Determination of wetting capabilityEN 1348:1997 Adhesives for tiles - Determination of tensile adhesion strength of cementitiousadhesivesEN 12002Adhesives for tiles - Determination of transverse deformation for cementitious adhesivesand groutsEN 12003Adhesives for tiles - Determination of shear adhesion strength of reaction resinadhesivesEN 12808-1Adhesives and grouts for tiles - Determination of chemical resistance of reaction resinmortars3Terms and definitionsFor the purpose of this standard the following terms and definitions are given:3.1General3.1.1thin bed methodmethod used for installing tiles onto a plane surface with an adhesive. The adhesive is usually applied witha trowel to obtain a layer and then combed with a notched trowel to achieve the right thickness andplanarity3.1.2fixing surfaceplane rigid surface upon which the tile is fixed3.1.3wall and floor tilestiles made out of ceramic (see EN 87) or natural and agglomerated stonesSIST EN 12004:2002

The adhesive are mixed with wateror liquid admix just before use3.2.2dispersion adhesive (D)mixture of organic binding agent(s) in the form of an aqueous polymer dispersion, organic additives andmineral fillers. The mixture is ready for use3.2.3reaction resin adhesive (R)mixture of synthetic resin, mineral fillers and organic additives in which hardening occurs by chemicalreaction. They are available in one or more component forms3.3Tools and working methods3.3.1notched troweltoothed tool, which makes it possible to apply the adhesive
as a series of ribs of a uniform thickness ontothe fixing surface and/or the reverse face of the tile3.3.2application to one surface only, «Notched trowel» or «Floating method»adhesive applied only to the fixing surface, usually with a trowel to obtain a uniform layer and then combedwith a notched trowel (see 3.1.1). The tiles are then fixed before a film forms on the surface of theadhesive3.3.3application to both surfaces, « Floating and buttering method »adhesive applied to the fixing surface and to the reverse of the tiles. The combined layer of adhesive doesnot exceed the maximum recommended thickness. The tiles are then fixed before a film forms on thesurface of the adhesive3.4Application properties3.4.1shelf lifetime of storage under stated conditions during which an adhesive may be expected to maintain its workingproperties3.4.2maturing timeinterval between the time when the cementitious adhesive is mixed and the time when it is ready for use3.4.3pot-lifemaximum time interval during which the adhesive can be used after mixing3.4.4open timemaximum interval after application at which tiles can be embedded in the applied adhesive and meet thespecified tensile adhesion strength requirement. It is measured following EN 1346SIST EN 12004:2002

surface area which can be measured by shear or tensile testing. It ismeasured following EN 1348:1997, EN 1324:1996 or EN 12003:1997 depending on the type of adhesive3.5.2deformabilitycapacity of a hardened adhesive to be deformed by stresses between the tile and the fixing surfacewithout damage to the installed surface3.5.3transverse deformationdeflection recorded at the centre when a beam of hardened adhesive is subjected to three point loading. Itis used to evaluate the deformability of the adhesive. It is measured following EN 120023.6Failure pattern3.6.1adhesion failure (AF-S or AF-T)when failure occurs at the interface between adhesive and substrate the notation AF-S is used, when itoccurs between tile and adhesive the notation AF-T is used and in both cases the test values equal theadhesion strength. See figure A.1, figure A.2.In some cases failure may occur in the adhesive layer between the tile and the pull-head plate. In thiscase the notation BT is used, see figure A.3, and the adhesion strength is greater than the test value. Thetest should be preferably repeated3.6.2cohesive failure within the adhesive (CF-A)when failure occurs within the adhesive layer, see figure A.43.6.3cohesive failure in the substrate or in the tile (CF-S or CF-T)when failure occurs within the substrate the notation CF-S is used, see figure A.5; when it happens withinthe body of the tile the notation CF-T is used, see figure A.6. In this case the strength of the adhesive isgreater than the test valueSIST EN 12004:2002
