4 Principles
The load-bearing capability ("pull off") of a kit is determined by subjecting a test specimen to tensional
force, applied evenly to its face through an elastic foam block and/or a lateral force, applied through the
reinforcement into the basecoat. Five combinations of tension and lateral shear loads can be tested
using the following methods:
— method A assesses the load-bearing capability with an increasing tension load (F ) only. No lateral
T
shear load is applied;
— method B assesses the load-bearing capability with an increasing tension load (F ) and a constant
T
lateral shear load (F ) in the plane of the reinforcement;
L
— method C assesses the load-bearing capability with an increasing tension load (F ) and a constant
T
lateral shear displacement (u ) in the plane of the reinforcement;
L
— method D assesses the load-bearing capability with an increasing lateral shear load (F ) in the
L
plane of the reinforcement and a constant tension load (F );
T
— method E assesses the load-bearing capability with an increasing lateral shear load (F ) in the
L
plane of the reinforcement. No tension load is applied.
5 Test equipment/apparatus
5.1 Substrates
5.1.1 General
The length and width of the substrate shall be equal or greater than the length and width of the test
specimen. The substrate shall be big enough to support the kit in case of lateral shear displacement.
5.1.2 Concrete substrate
The concrete shall have a minimum strength class of C12/15 according to EN 206 and a minimum
thickness of 70 mm.
For “mechanically fixed only” test specimens where a foil layer is omitted between the substrate and
thermal insulation in the test – see 5.2 – the roughness of the concrete substrate shall be determined
according to EN ISO 4287.
5.1.3 Timber substrate
The timber substrate may consist of more than one piece and may support only the setting positions.
NOTE A suitable material for the substrate is plywood of at least 20 mm thickness.
5.2 Foil
In the case of “mechanically fixed only” test specimens where no adhesive is used between the thermal
insulation product and substrate, a polyethylene or polypropylene foil layer may be placed on top of the
substrate to minimize the possibility of friction between the substrate and thermal insulation product
surfaces influencing the test result.
5.3 Foam blocks
The thickness shall be in the range of 300 mm to 500 mm. The thickness tolerance of every foam block
shall be ±3 mm. The nomin
