3、2:2008National forewordThis British Standard is the UK implementation of EN 12002:2008. Itsupersedes BS EN 12002:2002 which is withdrawn.Although the test described in this standard has been approved forpublication, there is little or no guidance available at present to relatetest results to perform

4、ance in service, and so it is unclear how such testvalues could inform the process of selecting adhesives and grouts fora particular application. There is also a danger that specifiers mightmistakenly assume deformability, as measured by the test described inthis standard, to be synonymous with flex

5、ibility, leading to erroneousassumptions about the performance of materials in service. Careshould therefore be taken in specifying transverse deformation testrequirements for a particular application, unless expert guidance isavailable. This caution also extends to the use of the terms “deformable”

6、and “highly deformable” to indicate categories of transverse deformationas listed in the product standard BS EN 12004:2007, in Tables 1 and 5and Clause 6.The UK participation in its preparation was entrusted to TechnicalCommittee B/539, Ceramic tiles and other rigid tiling.A list of organizations re

25、cope This European Standard specifies the test method to be used to determine the transverse deformation of cementitious ceramic tile adhesives and grouts. This European Standard is applicable to all cementitious ceramic tile adhesives and grouts for internal and external tile installations on floor

26、s 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

27、also be used for other kinds of tiles (natural and agglomerated stones, etc.), where these do not adversely affect these materials. 2 Normative references The following referenced documents are indispensable for the application of this document.

29、SO 15605, Adhesives Sampling (ISO 15605:2000) 3 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 a

30、nd 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. 4 Sampling Take a samp

31、le of at least 2 kg of the adhesive or grout in accordance with EN ISO 15605 and EN 1067. 5 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.

The adhesive or grout to be tested shall be within its shelf life, whe

33、re 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.

34、6.4 Support Rigid, smooth and flat support for the polyethylene film. 7 Apparatus 7.1 Anvil A metallic construction conforming to the dimensions. See Figure 1. 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 Fi

35、gure 2. 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 2 mm diameter drilled at each internal corner is recommended to e

37、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 2 mm/min. 7.6 Flow table The flow table used for the

38、compaction of (280 1) mm x (45 1) x (5 0,1) mm specimen shall comply with EN 459-2. 8 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 val

39、ues is given, the mean shall be used). Prepare a minimum of 2 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 t

40、he dry powder over the liquid; mix for 30 s; take out the mixing paddle; scrape down the paddle and pan within 1 min; replace the paddle and mix for 1 min. If required by the adhesive or grout manufacturers instructions, let the adhesive or grout mature and then mix for a further 15 s. 9 Procedure 9

41、.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

42、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. Copyright European Committee for Standardization Provided by IHS under license with CENNot for R

Apply a layer of release agent to the template B and position it centrally over the specimen. Load the

44、 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

45、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

46、 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 th

47、eir 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.

48、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 2 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 deformatio
