EN 1346:2007 – Adhesives for tiles – Determination of open time
1 Scope
This European Standard specifies the test method for the determination of the open time of ceramic tile adhesives.
This European Standard is applicable to all ceramic tile adhesives for internal or external 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 also be used for other types of tiles (natural and agglomerated stones etc.), if they do not adversely affect the stones.

3 Sampling
Take a 2 kg 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 the air speed in the testing area less than 0,2 m/s.
5 Test materials
5.1 General
Condition all test materials (adhesive etc.) 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 new, clean and dry.
The tiles used for this method shall be of the following type:
type P1: glazed porous body tile complying with EN 14411, group BIII, of water absorption (15 ± 3) % by mass,with a thickness in the range 7 mm to 10 mm and a profile back pattern less than 0,25 mm deep, cut to facial dimensions of (50 ± 1) mm × (50 ± 1) mm.
5.3 Concrete slab
The concrete slab shall comply with EN 1323.
6 Apparatus
6.1 Notched trowel
A notched trowel having 6 mm × 6 mm notches at 12 mm centres.
6.2 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.
6.3 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.
6.4 Test 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.
