Security Compliance Testing
Invisi-Gard put their screens through tough conditions in independent testing facilities to ensure their products are tested to not just meet but exceed Australian Standards. Central Security Screens do not compromise on the quality of the 316 stainless steel mesh, the frame, or the locking mechanism used.
Dynamic Impact Test: AS5039-2008
- This Australian Standard test simulates a kick to a security screen door.
- This test was introduced after it was found that grilles fitted to security screen doors were subject to impact breakage through kicking of the grille panel.
- The test is performed with a sand- and lead-filled bag weighing around 40 kg.
- At impact the bag imparts 100 joules of energy to the panel being tested. The test is repeated 5 times, simulating repeated kicking as the burglar attempts to break into your home.
- The test panel fails the test if the infill material (mesh) comes out of the door or window framing or if the impact breaches the material in any way.
- The Australian Standard AS5041 requires security screens and doors to resist five consecutive impacts, each of 100 joules.
- Invisi-Gard easily meets this requirement and can resist in excess of 50 consecutive impacts, each of 100 joules, without failure.
- Invisi-Gard passes because of our patented EGP Retention System, which runs around four sides of the screen.
- This patented retention system resists the tendency of the mesh to be pulled out of the frame.
Jemmy Test: AS5039-2008
- The effects of a jemmy attack against a security screen door or window grille are simulated by allowing a standardised narrow-bladed lever (representing a large screwdriver) to be inserted against the locking, fastening, and hinging points, and a turning force (torque) is applied to those points via the lever.
- If all the hinges and/or all the locking and/or all the fastening points tested have failed, then the security screen door or window grille shall have failed. No part of the edge of the security screen door or window grille shall have deflected to the extent that the gap between the security screen door or window grille and the door or window frame is greater than 15 cm, perpendicular to the door or window frame, after the jemmy test has been completed.
- Invisi-Gard products pass this test thanks to the quality of our hardware and the stiffness of our aluminium section framing. Also, all Invisi-Gard hinged security doors are manufactured with three-point locks as a standard feature. Three-point locks provide higher security, as not only does the lock engage in the centre position, but also it has extra latches towards the top and bottom of the door that give even more strength.
Knife Shear Test: AS5039-2008
- 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.
- 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 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 15 cm or greater is achieved after the third draw. Invisi-Gard passes this test in both the warp and fill directions, unlike many imported meshes, which only pass in one direction.
- Invisi-Gard is able to pass this test thanks to the strength of the 316 Marine Grade Stainless Steel Mesh!
