Invisi-Gard by Verosol Knife Shear Test: AS5039-2008

This Australian Standard test simulates a knife attack on Invisi-Gard by Verosol 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.

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

During this test, a specially designed machine draws a knife blade along a line down a panel three times.

After each draw, the used blade is replaced with a new one. The sample fails if a continuous cut of 15cm or greater is achieved after the third draw. Invisi-Gard by Verosol passes this test in both the warp and fill directions, unlike many imported meshes which only pass in one direction.
