EN1607 – Determination of tensile strength perpendicular to faces of Thermal Insulation Products.
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 used in building applications.
In principle the test specimen are bonded between two rigid plates or blocks and fastened in a tensile testing machine. The application is a pulling operation at a given test speed until failure. When failure occurs, the maximum tensile strength perpendicular to the product faces is determined, based on max load divided by the cross-sectional area of the test specimen.
We suggest using a tensile testing system of dual-column tabletop design together with the test fixture specimen dependent and selectable.
Tensile Plate sizes to the standard:
- 50mm x 50mm
- 100mm x 100mm
- 150mm x 150mm
- 300mm x 300mm
Test fixture: One set of tensile plates to meet the standard for testing specimens. The plates have alignment to ensure that only axial force is applied on the test specimen.
For this test type, we use the specimen protect feature of Bluehill when loading the specimen and fixture into the machine to prevent any overloading of specimen during this process prior to test. We then in the test method drive to a preload to eliminate any slack in the specimen then test to failure is carried out. 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 EN1607 to fully understand the test fixture and results requirements prior to performing any tests.
