Test Laboratory Accreditation
Since November 2016 our Test Laboratory accreditation to ISO 17025:2005, enables us to perform the following tests for our customers:
Test Standard Description
Lap Shear ASTM D1002-10 A method for testing adhesion by pulling bonded layers apart along the plane of adhesion.
T-Peel ASTM D1876-08 A good accurate method of assessing the quality of a joint but is only applicable for flexible test pieces for example aluminium foil. An example would be the force it takes to pull tape off a roll.
Climbing Drum ASTM D1781-98 A peel test but designed to understand the bond between a surface, or ‘skin’ and a sub-straight. In our case we usually test the bond between honeycomb aluminium and an aluminium skin.
Flatwise Tensile ASTM C297/C296M-16 Test specimens are cut from sandwich panels, and the faces of these specimens are bonded to aluminium blocks. The aluminium blocks are mounted in a universal test machine and pulled apart. This force, along with the area of the specimen is used to establish the bond strength.
We use a Universal Test Machine( Inston or LLoyds machine) for each of the above test. the samples are pulled apart at a pre-determined rate (mm per min), the force required to do this is continuously measured and recorded. This information is used to assess the strength of the bond.
