ISO 13007-2:2013 pdf download.Ceramic tiles – – Grouts and adhesives -Part 2:Test methods for adhesives.
This part of Iso 13007 describes the methods for determining the characteristics for adhesives used in
the installation of ceramic tiles. The following test methods are described:
— determination of open time (41);
— determination of slip (4.2);
— determination of shear adhesion strength (4.3);
— determination of tensile adhesion strength (4.4);
— determination of transverse deformation (4.5).

3 General test conditions and procedures
3.1 Sampling
A representative sample of at least 2 kg shall be used.
3.2 Test conditions
Standard conditions shall be (23 ± 2) °C and (50 ± 5) % relative humidity and the speed of air in the testing area shall be less than 0,2 rn/s. Other test conditions may be specified in Clause 4. The tolerance in the time of conditioning for all test specimens shall be as shown in Table 1 below.
3.3 Test materials
Condition all test materials, including water, for at least 24 h under standard conditions. The adhesive to be tested shall be within its shelf life, where this is specified.
3.3.1 Ceramic tiles
The tiles shall be checked prior to conditioning to ensure that they are unused, clean, and dry. The type of tile shall be as specified under the specific test procedures found in Clause 4.
3.4 Mixing procedures
3.4.1 Cementitious adhesives (C)
The amount of water and/or liquid admix required for preparing the adhesive shall be as stated by the manufacturer in parts by weight, i.e. liquid to dry powder (in cases where a range of values is given, the average shall be used).
Using a minimum quantity of 2 kg of the powder and the recommended quantity of liquid, prepare the adhesive in a planetary mixer using the following slow speed settings: (140 ± 5) rotations per minute and (62 ± 5) rotations per minute planetary movement. See Figures 1 and 2.
Carry out the following procedure.
1) Pour the liquid into the pan.
2) Scatter the dry powder over the liquid.
3) Mixfor30s.
4) Take out the mixing paddle.
5) Scrape down the paddle and pan within 1 min.
6) Replace the paddle and mix for 1 min.
If required by the adhesive manufacturer’s instructions, let the adhesive mature as specified and then mix for an additional 15 s.
3.4.2 Dispersion adhesive (D) and reaction resin adhesive (R)
Where ready-to-use dispersion adhesives or reaction resin adhesives are to be used, the manutacturers instructions shall be followed.ISO 13007-2 pdf download.
