This European Standard does not contain performance requirements or recommendations for the design and installation of ceramic tiles. The following test methods are described: determination of open

24、 time (8.1); determination of slip (8.2); determination of tensile adhesion strength for cementitious adhesives (8.3); determination of shear adhesion strength of dispersion adhesives (8.4); determination of shear adhesion strength of reaction resin adhesives (8.5); determination of transverse defor

25、mation of cementitious adhesives (8.6). NOTE Ceramic tile adhesives can be used also for other kinds of tiles (natural and agglomerated stones, etc.), if they do not adversely affect the stones. WARNING This European Standard can involve hazardous materials and operations. Persons using this standar

26、d should be familiar with normal laboratory practice. This European Standard does not purport to address all the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any European and

27、national regulatory conditions. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

The tolerance in the time of conditioni

31、ng for all test specimens shall be as shown in Table 1 below: Table 1 Allowed tolerance in testing time for all samples requiring conditioning Sample Conditioning Time Allowed tolerance for testing 6 h 15 min 7 d 3 h 14 d 6 h 21 d 9 h 28 d 12 h Testing shall be performed within the specified time wi

32、ndow. 5 Test materials 5.1 General Condition all test materials for at least 24 h under standard conditions. The adhesive to be tested shall be within its shelf life, where this is specified. 5.2 Ceramic tiles The tiles shall be checked prior to conditioning to ensure that they are unused, clean and

33、 dry. The type of tile shall be as specified under the specific test procedures found in Clause 8. 5.3 Test substrate 5.3.1 Concrete slab The concrete slab shall be at least 35 mm thick, have a moisture content of less than 3 % by mass (carbide method) and have a water absorption at the surface afte

34、r 4 h in the range of 0,5 cm3to 1,5 cm3. The tensile adhesion strength shall be at least 1,5 N/mm2. The test surface shall have a finish similar to that obtained by using a wooden float and be clean and dust-free at the time of the test. A method for manufacturing a suitable concrete test slab and t

35、he procedures for measuring the performances are given in Annex A. 5.3.2 Other substrates Other substrates may be used upon agreement if the substrate is recommended for ceramic tile application by the adhesive manufacturer. To demonstrate compatibility with other optional substrates, the adhesive s

36、hall be applied to the selected substrate in accordance with the open time test method (8.1). When the result of 0,5 N/mm2is achieved or cohesive failure occurs in the substrate, the requirement is considered satisfied. BS EN 12004-2:2017EN 12004-2:2017 (E) 7 6 Mixing of the adhesive The amount of w

37、ater and/or liquid admix required for preparing the cementitious adhesive shall be as stated by the manufacturer in parts by mass, i.e. liquid to dry powder (in the case where a range of values is given, the average shall be used). Prepare a minimum quantity of 2 kg of the adhesive in a mixer of the

38、 type described in EN 196-1:2016, 4.4, using the slow speed settings (140 5) rotations per min and (62 5) revolution planetary movement. Carry out 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

39、paddle and pan within 1 min; replace the paddle and mix for 1 min. Let the adhesive mature as specified in the manufacturers instructions, and then mix for a further 15 s. Where ready-to-use dispersion adhesives or reaction resin adhesives are to be used, the manufacturers instructions shall be foll

46、hall be capable of applying the load to the pull-head plate at the rate of (250 50) N/s through a suitable fitting that does not exert any bending force. 8.1.3 Procedure Apply a thin layer of the adhesive, mixed in accordance with Clause 6, to the concrete slab with a straight edge trowel. Then appl

47、y a thicker layer and comb with the notched trowel (8.1.2.1). The trowel shall be held at an angle of approximately 60 to the substrate at a right angle to one edge of the slab and drawn across the slab parallel to that edge (in a straight line).
