4 Principle
The tensile bond strength of the adhesive, the reinforced base coat or the rendering system to the
thermal insulation product is determined by applying a direct tensile load perpendicular to the faces of
the individual test specimen.
5 Test apparatus/materials
5.1 Glue
The glue shall be capable of providing a strong bond between the metal pull head plates, the adhesive,
the reinforced base coat or the rendering system. The glue shall also be capable of achieving a strong
bond between the optional substrate and the thermal insulation product. Solvent free epoxy or
polyurethane glue has been found suitable for this purpose. The glue shall not damage or react
chemically with the adhesive, thermal insulation product, the reinforced base coat or the rendering
system. It shall not influence the results.
5.2 Pull head plates
The square metal pull head plates with a thickness of at least 5 mm shall have dimensions of
(50 ± 1) mm × (50 ± 1) mm, (100 ± 1) mm × (100 ± 1) mm, (150 ± 1) mm × (150 ± 1) mm or
(200 ± 1) mm × (200 ± 1) mm. The pull head plates shall have sufficient rigidity to prevent any negative
influence on the test results. They shall have a central fitting for the connection to the tensile testing
machine via a self-aligning attachment (universal coupling) to ensure that an even distribution of
tensile stress is applied to the individual test specimen during test. The face of the pull head plates to
which the glue is to be applied shall be flat to a tolerance of ±0,5 mm per 100 mm length.
5.3 Cutting device
Circular saw, angle grinder or an oscillating cutting device incorporating guides to facilitate a straight
cut.
5.4 Tensile testing machine
Tensile testing machine, appropriate for the range of force and displacement involved and having a
constant rate of displacement of (10 ± 1) mm/min or an average load increase of 50 N/s. It shall be
capable of measuring the force to an accuracy of ±1 %.
5.5 Specimen securing frame
The frame is used in conjunction with the tensile testing machine to clamp the individual test specimen
to the base of the machine and to ensure the applied load is distributed evenly onto the surface of the
specimen. The frame is made of metal plates with a minimum thickness of 5 mm. The size of the frame
should allow it to sit within the upper surface area of the test specimen. The square recess of the frame
shall be (10 ± 1) mm larger than the individual test specimen.
