Joint Testing

Flow Fastening Technology

Pretest: -  2 complete test part

are needed for each test series to determine Ti, Ts and Tt

27

Joint Testing

Flow Fastening Technology Sheering Test: -  A screw is driven

into the 2 layers then the layers are pulled to failure recording the required force.

-  A Minimum of 5 parts should be tested per joint.
