Date Comments

National foreword

This British Standard is the UK implementation of EN 12002:2008 It supersedes BS EN 12002:2002 which is withdrawn

Although the test described in this standard has been approved for publication, there is little or no guidance available at present to relate test results to performance in service, and so it is unclear how such test values could inform the process of selecting adhesives and grouts for

a particular application There is also a danger that specifiers might mistakenly assume deformability, as measured by the test described in this standard, to be synonymous with flexibility, leading to erroneous assumptions about the performance of materials in service Care should therefore be taken in specifying transverse deformation test requirements for a particular application, unless expert guidance is available This caution also extends to the use of the terms “deformable” and “highly deformable” to indicate categories of transverse deformation

as listed in the product standard BS EN 12004:2007, in Tables 1 and 5 and Clause 6

The UK participation in its preparation was entrusted to Technical Committee B/539, Ceramic tiles and other rigid tiling

A list of organizations represented on this committee can be obtained on request to its secretary

This publication does not purport to include all the necessary provisions

of a contract Users are responsible for its correct application

Compliance with a British Standard cannot confer immunity from legal obligations.

1 Scope

This European Standard specifies the test method to be used to determine the transverse deformation of cementitious ceramic tile adhesives and grouts

This European 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 non-cementitious adhesives and grouts , e.g dispersion and reactive resin adhesives and grouts

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 kinds of tiles (natural and agglomerated stones, etc.), where these do not adversely affect these materials

2 Normative references

The following referenced documents are indispensable for the application of this document For dated references, only the edition cited applies For undated references, the latest edition of the referenced document (including any amendments) applies

EN 196-1:2005, Methods of testing cement – Part 1: Determination of strength

EN 459-2, Building lime – Part 2: Test methods

EN 1067, Adhesives – Examination and preparation of samples for testing

EN ISO 15605, Adhesives – Sampling (ISO 15605:2000)

3 Principle

The test described in this European Standard measures the transverse deformation of cementitious adhesives and grouts, when subjected to a 3-point bending load, performed on test specimens of the stated dimension The specimens are prepared and conditioned in accordance with the specific conditions described

NOTE Transverse deformation is used to evaluate the deformability of the adhesive, i.e its capacity to be deformed

by stresses between the tile and the fixing surface without damage to the installed surface

4 Sampling

Take a sample of at least 2 kg of the adhesive or grout in accordance with EN ISO 15605 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

6.2 Substrate

Shall be polyethylene film of minimum thickness 0,15 mm

6.3 Plastic container

A plastic container that 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 x (400 ± 10) mm x (110 ± 10) mm

6.4 Support

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 x (45 ± 1) mm and thickness (5 ± 0,1) mm; e.g made from polytetrafluoroethylene (PTFE) or metal

NOTE A 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 producing a test specimen of dimensions (300 ± 1) mm x (45 ± 1) mm x (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 x (45 ± 1) x (5 ± 0,1) mm specimen shall 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 of 2 kg of powder in a mixer of the type described in clause 4.4 of EN 196-1:2005, using the slow speed settings, (140 ± 5) r/min rotation and (62 ± 5) r/min 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 mixing paddle;

 scrape down the paddle and pan within 1 min;

 replace the paddle and mix for 1 min

If required by the adhesive or grout manufacturer’s instructions, let the adhesive or grout mature and then mix for a further 15 s

9 Procedure

9.1 Preparation of substrate

Fix the polyethylene film (6.2) firmly to the rigid support (6.4), ensuring the surface, to which the adhesive is to

be applied, is not distorted, e.g without pleats or wrinkles

9.2 Preparation of 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

BS EN 12002:2008

EN 12002:2008 (E)

7

Lift the mould gently 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 x 45) mm The applied 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 to 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 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 three 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 specimen on the test jig (7.2)

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 in millimetres

When no cracking occurs, report the 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

11 Test report

The test report shall provide the following information:

a) name, number and issue of this European Standard;

b) place, date and time of sampling;

c) type of adhesive or grout, commercial designation and manufacturer;
