This European Standard specifies the equipment and procedures for determining the tensile strength of a product perpendicular to its faces. It is applicable to thermal insulating products.
Tensile strength is maximum recorded tensile force perpendicular to the product faces during the pulling operation, divided by the cross-sectional area of the test specimen.
A test specimen is attached between two rigid plates or blocks, fastened in a tensile testing machine and pulled apart at a given speed.
The maximum tensile force is recorded and the tensile strength of the test specimen is calculated.
