20、ation of cementitious ceramic tile adhesives and grouts. This 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 ceramic tile adhesives and grouts which possess elastomeric properties,
21、 such as many dispersions and reaction resin adhesives and grouts. This European Standard does not contain performance requirements or recommendations for the design and installation of ceramic tiles. NOTECeramic tile adhesives can also be used for other kinds of tiles (natural and agglomerated ston
22、es, etc.), where these do not adversely affect these materials. 2 Normative references This 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 listed he
23、reafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN 196-1:1

The specimens are prepared and conditioned in accordance with the specific conditions described. 4 Sampling Take a sample of at least 2 kg of the adhesive or grout i
26、n accordance with EN 1066 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. 6 Test materials Condition all test materials for at least 24 h under standard conditions. The adhesive or grout to be tested sh
27、all be within its shelf life, where this is specified.

28、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 (400 10) mm (110 10) mm. 6.3 Support Rigid, smooth and flat support for the polyethylene film. 7 Apparatus 7.1 Anvil A metallic construction conforming to the dimensions
29、. 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 Figure 2. 7.3 Template A A smooth, rigid, non absorbent rectangular frame of internal dimensions (280 1) mm (45 1) mm and thickness (5 0,1) mm; e.
30、g. made from polytetrafluoroethylene (PTFE) or metal. NOTEA round hole of approximately 2 mm diameter drilled at each internal corner is recommended to ease production of the test piece. See Figure 3. 7.4 Template B A smooth, rigid, non-absorbent mould (see Figure 4) or similar device capable of pro
31、ducing a test specimen of dimensions (300 1) mm (45 1) mm (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 compaction of (280 1) mm (45 1) mm (5 0,1) mm specimen sh
32、all 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 values is given, the mean shall be used). Prepare a minimum o
33、f 2 kg of powder in a mixer of the type described in 4.4 of EN 196-1:1994, using the slow speed settings, (140 5) min-1 rotation and (62 5) min-1 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
34、 mixing paddle; Licensed Copy: sheffieldun sheffieldun, na, Sat Oct 28 16:26:41 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 12002:2002 (E) 6 - 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 t
35、he adhesive or grout mature and then mix for a further 15 s. 9 Procedure 9.1 Preparation of substrate Fix the polyethylene film (6.1) firmly to the rigid support (6.3), ensuring the surface, to which the adhesive is to be applied, is not distorted, e.g. without pleats or wrinkles. 9.2 Preparation of
36、 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. Lift the mould gently
37、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 45) mm. The appli
38、ed 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 t
39、o 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
40、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 thr
41、ee 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
42、specimen on the test jig (7.2). If the test specimen is deformed, measure the deformation, then 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 from the horizontal plane, in mm. When no cracking occurs, report th
43、e 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. The cementitious adhesives are defined in two classes according to the me
44、asured transverse deformation value.
