Tensile Testing of Thin Metal Foil

Tensile testing of thin metallic specimens such as aluminum foil may be performed using the test procedures specified in ASTM E8 and other relevant standards; however, due to the fragile state of the thin test strip a conventional extensometer may put unnecessary stress on the sample and cause premature failure. To avoid this error it is recommended that a non contacting extensometer be used.
