EN 1348:2007 - Adhesives for tiles - Determination of tensile adhesion strength for cementitious adhesives

1 Scope
This European Standard specifies a method for the determination of the tensile adhesion strength of cementitious ceramic tile adhesives.
This European Standard is applicable to all cementitious adhesives and cementitious adhesives with separate components for internal and external ceramic tile installations on walls and floors.
This European Standard does not contain performance requirements or recommendations for the design and installation of ceramic tiles.
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.

3 Sampling
Take, at least, 2 kg test sample of the adhesive in accordance with EN ISO 15605 and EN 1067.
4 Test conditions
Standard conditions shall be (23 ± 2) °C and (50 ± 5) % relative humidity and a speed of air in the testing area of less than 0,2 m/s.
5 Test materials
5.1 General
Condition all test materials (adhesive etc.) to be tested for at least 24 h under standard conditions. The adhesive to be tested shall be within its shelf life, where this is specified.
6 Apparatus
6.1 Weight
A mass capable of exerting a force of (20 ± 0,05) N, with a cross sectional area of less than 50 mm × 50 mm.
6.2 Pull-head plates
Square metallic plates, with dimensions of (50 ± 1) mm × (50 ± 1) mm and a minimum thickness of 10 mm,with a suitable fitting for connection to the test machine.
6.3 Tensile testing machine
A test machine for direct pull tensile force test and with suitable capacity and sensitivity for the test. The machine shall 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.
6.4 Air-circulating oven
An air-circulating oven capable of controlling the temperature to within ± 3 °C.
6.5 Notched trowel
A notched trowel having 6 mm × 6 mm notches at 12 mm centres.
