Knife Shear Test

This Australian Standard test simulates a knife attack on Invisi-gard as a burglar tries to cut through the screen. The test aims to recreate the effect of someone attacking your doors with a Stanley knife or similar.

During the test a specially designed machine draws the knife along a 25cm line down the test panel 3 times. The sample fails if a continuous penetration measuring more than 15cm is achieved after the 3 passes.

Invisi-gard is able to pass this test thanks to the strength of the 316 Marine Grade Stainless Steel Mesh.
