This European Standard specifies the equipment and procedures for determining the tensile strength of a product parallel to its faces. It is applicable to thermal insulating products used in building applications. This standard is used to determine whether the product has sufficient strength to withstand stresses during transportation and application.
In principle the test specimen is attached to two clamps, which are 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. The test specimens is cut from the full size product so that the length direction corresponds to the direction in which the tensile force is applied to the product in its application.
Test specimen overall size: (L) 1000mm (D) 500mm (T) 100mm
We suggest using a tensile testing system of dual-column design together using a set of tensile grips for testing in accordance with the testing standard. The vertical test daylight of the load frame is important as the test fixture and specimen effective vertical length at the start of test is large.
Attach the test specimen centrally between two clamps to distribute the stress uniformly. Run the test method to drive to a preload to eliminate any slack in the specimen then test at a constant speed of the crosshead of 10mm/min until failure occurs. For this test, it is important to have a high-speed intelligent test data sampling rate of 100 Hz to the PC ensure the capture and record of the maximum tensile strength.
We recommend using Bluehill test software package to input specimen parameters, set the desired speed control, automatically calculate the desired results and statistics, and finally to product a test report or send to a network database.
We suggest reviewing EN1608 to fully understand the test fixture and results requirements prior to performing any tests.
