It represents combined in-plane biaxial tension and out-of-plane compression. A punch test with a small radius punch head is one of the standard abuse tests for lithium-ion battery separators. It is performed with a punch of 3.2 mm in diameter according to ASTM F1306-90, and usually referred to as a puncture test 25.
Using a footswitch for actuation of the pneumatic grips frees the hands of the operator so securing of the battery separator is fast and efficient. To ensure stability and efficiency in the puncture test of the battery separator, the materials tester combined with a pneumatic puncture test fixture is the ideal solution.
