Pull-off / Pull-out | Mecmesin

'Pull-off' or 'pull-out' testing generally involves the separation of two secured parts under tension.

This may be to test joints in assemblies of any kind ranging from the tensile strength of crimped or welded wire terminals, the seal integrity of adhesive joints, the mechanical strength of industrial fixings and fasteners, stoppers, lids and push-fit closures, through to household fabric fastenings and trimming. In these tests, each part of a test sample must be held securely in a tensile grip, but in such a way as to not deform or weaken the component under test.

Tensile force is then applied at a constant rate to ensure maximum repeatability between tests. The test can be destructive and runs until the component pulls off or breaks. Alternatively, it can be non-destructive and set to run to a pre-determined load limit or displacement. The maximum tension applied is recorded, preferably with a test system operating at a high data-capture rate so that any sudden peak forces are not missed.
