BRITISH STANDARD Adhesives for tiles — Determination of transverse deformation for cementitious adhesives and grouts ICS 83.180; 91.100.10 NO COPYING WITHOUT BSI PERMISSION EXCEPT AS PERMITTED BY COPYRIGHT LAW BS EN 12002:2008 BS EN 12002:2008 National foreword This British Standard is the UK implementation of EN 12002:2008 It supersedes BS EN 12002:2002 which is withdrawn Although the test described in this standard has been approved for publication, there is little or no guidance available at present to relate test results to performance in service, and so it is unclear how such test values could inform the process of selecting adhesives and grouts for a particular application There is also a danger that specifiers might mistakenly assume deformability, as measured by the test described in this standard, to be synonymous with flexibility, leading to erroneous assumptions about the performance of materials in service Care should therefore be taken in specifying transverse deformation test requirements for a particular application, unless expert guidance is available This caution also extends to the use of the terms “deformable” and “highly deformable” to indicate categories of transverse deformation as listed in the product standard BS EN 12004:2007, in Tables and and Clause The UK participation in its preparation was entrusted to Technical Committee B/539,

adhesives and grouts This European Standard is applicable to all cementitious ceramic tile adhesives and grouts for internal and external tile installations on floors and walls It is not applicable to non-cementitious adhesives and grouts , e.g dispersion and reactive resin adhesives and grouts This European Standard does not contain performance requirements or recommendations for the design and installation of ceramic tiles NOTE Ceramic tile adhesives can also be used for other kinds of tiles (natural and agglomerated stones, etc.), where these not adversely affect these materials Normative references The following referenced documents are indispensable for the application of this document For dated references, only the edition cited applies For undated references, the latest edition of the referenced document (including any amendments) applies EN 196-1:2005, Methods of testing cement – Part 1: Determination of strength EN 459-2, Building lime – Part 2: Test methods EN 1067, Adhesives – Examination and preparation of samples for testing EN ISO 15605, Adhesives – Sampling (ISO 15605:2000) Principle The test described in this European Standard measures the transverse deformation of cementitious adhesives and grouts, when subjected to a 3-point bending load, performed on test specimens of the stated dimension The specimens are prepared and conditioned in accordance with the specific conditions described NOTE Transverse deformation is used to evaluate the deformability of the adhesive, i.e its capacity to be deformed by stresses between the tile and the fixing surface without damage to the installed surface Sampling Take a sample of at least kg of the adhesive or grout in accordance with EN ISO 15605 and EN 1067 Test conditions Standard conditions shall be (23 ± 2)°C and (50 ± 5)% R.H and air velocity in the working area of less than 0,2 m/s BS EN 12002:2008 EN 12002:2008 (E) Test materials 6.1 General Condition all test materials for at least 24 h under standard conditions The adhesive or grout to be tested shall be within its shelf life, where this is specified 6.2 Substrate Shall be polyethylene film of minimum thickness 0,15 mm 6.3 Plastic container A plastic container that is capable of being sealed to make it air tight, with an internal volume of (26 ± 5) l, e.g a container with dimensions (600 ± 20) mm x (400 ± 10) mm x (110 ± 10) mm 6.4 Support Rigid, smooth and flat support for the polyethylene film Apparatus 7.1 Anvil A metallic construction conforming to the dimensions See Figure 7.2 Test jig Two metallic cylindrical supports, of diameter (10 ± 0,1) mm, spaced (200 ± 1) mm centre to centre, of length 60 mm minimum See Figure 7.3 Template A A smooth, rigid, non absorbent rectangular frame of internal dimensions (280 ± 1) mm x (45 ± 1) mm and thickness (5 ± 0,1) mm; e.g made from polytetrafluoroethylene (PTFE) or metal NOTE A round hole of approximately mm diameter drilled at each internal corner is recommended to ease production of the test piece See Figure BS EN 12002:2008 EN 12002:2008 (E) 7.4 Template B A smooth, rigid, non-absorbent mould (see Figure 4) or similar device capable of producing a test specimen of dimensions (300 ± 1) mm x (45 ± 1) mm x (3 ± 0,05) mm 7.5 Test machine The test machine shall be a press, capable of applying the anvil (7.1) to the test piece at a rate of mm/min 7.6 Flow table The flow table used for the compaction of (280 ± 1) mm x (45 ± 1) x (5 ± 0,1) mm specimen shall comply with EN 459-2 Mixing of adhesive or grout The amount of water and/or liquid admix required for preparing the adhesive or grout shall be as stated by the manufacturer in parts by mass, i.e liquid to dry powder (if a range of values is given, the mean shall be used) Prepare a minimum of kg of powder in a mixer of the type described in clause 4.4 of EN 196-1:2005, using the slow speed settings, (140 ± 5) r/min rotation and (62 ± 5) r/min planetary movement using the following procedure: pour the liquid into the pan; scatter the dry powder over the liquid; mix for 30 s; take out the mixing paddle; scrape down the paddle and pan within min; replace the paddle and mix for If required by the adhesive or grout manufacturer’s instructions, let the adhesive or grout mature and then mix for a further 15 s Procedure 9.1 Preparation of substrate Fix the polyethylene film (6.2) firmly to the rigid support (6.4), ensuring the surface, to which the adhesive is to be applied, is not distorted, e.g without pleats or wrinkles 9.2 Preparation of test units Hold the template A firmly onto the polyethylene film Trowel sufficient adhesive across the template and then screed clean so as to neatly and completely fill the hole in the template Clamp the mould firmly to the flow table and compact the sample using 70 jolts BS EN 12002:2008 EN 12002:2008 (E) Lift the mould gently from the flow table and carefully remove the template vertically Apply a layer of release agent to the template B and position it centrally over the specimen Load the template with a weight capable of exerting a force of (100 ± 0,1) N and an approximate cross-sectional area of (290 x 45) mm The applied pressure ensures that the material fully fills the recess of the template to the required thickness Remove any excess material from the sides of the template and one hour later remove the weight After 48 h remove the template B Prepare six samples for each test Condition the units according to the test requirements 9.3 Conditioning Immediately after the removal of template B place six specimens, on the support, horizontally into the plastic container and make it air tight Condition the test units at (23 ± 2)°C After 12 days remove them from the plastic container and condition them for 14 days in air in standard conditions 9.4 Transverse deformation After conditioning has been completed, remove the specimens from the polyethylene film and measure their thickness, using a caliper with 0,01 mm precision, at three positions, i.e in the middle and (50 ± 1) mm from each end If the three values fall within the required tolerance of (3,0 ± 0,1) mm calculate the average value; discard any specimen which falls outside the required permissible thickness If less than three specimens are acceptable repeat the test The sample shall be flat when resting on a flat surface Place the test specimen on the test jig (7.2) Deform it with a transverse load applied by the anvil (see Figure 2) at a rate of mm/min until failure occurs Record the deformation in millimetres When no cracking occurs, report the maximum force and deformation Repeat the test on the other test pieces 10 Expression of results The transverse deformation is determined to 0,1 mm, by calculating the average value of the deformations obtained in the test 11 Test report The test report shall provide the following information: a) name, number and issue of this European Standard; b) place, date and time of
