Dynamic Impact Test
The test: The dynamic impact test is designed to simulate an intruder trying to kick his way through a security door or window. The test is performed with a bag full of lead shot and sand, weighing more than 40 kg. The bag is smashed into the security screen with a force of 100 joules – beyond most burglars. The test is repeated 5 times.
The result: Passed. All four Prowler Proof Diamond designs easily pass the dynamic impact test. Have a look at the video to see just how easily a Prowler Proof Diamond security screen absorbs the impact.
Your benefit: Kicking your way through a Prowler Proof Diamond design security screen is all but impossible. It handles the Australian Standards test for dynamic impact with ease – the test sample still looks brand new after the test.
The test: The jemmy test is designed to simulate an intruder using a lever to get past the security door or window. The test is performed with a large screwdriver at all locking, hinging and fixing points. The force applied is up to 450 N (45 kg) for 20 seconds – way beyond the capability of most potential intruders.
The result: Passed. The jemmy test is no match for the Prowler Proof Diamond design security doors – all locking and fixing points are secure after the test. The test couldn't even be performed on the Diamond design security windows – the dynamic impact test left no gap to insert the screwdriver!
Your benefit: It takes much more than a large screwdriver to get past a Prowler Proof Diamond design security screen. Even with substantial force applied, the locking and fixing points just won't give way.
The test: Imagine an intruder trying to pull out your security screen…that’s what the pull test is all about. The security door or window must be able to withstand pulling forces of up to 2 kN (200 kg) for 20 seconds at various positions from various angles.
The result: Passed. It's virtually impossible to separate the mesh from the welded frame of a Prowler Proof Diamond design security screen. 200 kg is a substantial force – still the screen looks unaffected upon completion of the test.
Your benefit: A potential intruder will need to pull substantially more than 200 kg at various positions for an extended period of time to have any hope of getting past a Prowler Proof Diamond design security screen. Good luck with that.
The test: The probe test simulates an intruder having created a gap and trying to get his hand inside to unlock a door or a window. A deflecting force of 1.5 kN (150 kg) is applied to each opposite side of the opening to increase the space enough to get a hand through.
The result: Passed. The test simply can't be performed on any Prowler Proof Diamond design. The openings in the mesh are far smaller than the test requirement of a 213 mm diameter probe.
Your benefit: A Prowler Proof Diamond design security screen significantly restricts a would be intruder from gaining access to inside your home.
The test: Cutting pliers are popular tools among burglars. The shear test simulates a cutting plier attack on a security screen. The shearing tool applies increasing pressure until the sample chord breaks. The force required to break one chord must be at least 3 kN (300 kg).
The result: Passed. No matter which Prowler Proof Diamond design security screen you choose, it takes much more than 300 kg of force to break a chord with cutting pliers.
Your benefit: Even armed with cutting pliers a potential intruder will have to leave your home empty-handed. He won't be able to apply enough force to break a chord in the aluminium grille – much less all the chords needed to gain access.
Knife Shear Test
The test: The knife shear test simulates a knife attack on your security screen. A heavy duty trimming knife is dragged along a
250 mm line with a force of 150 N (15 kg) vertically and up to 350 N (35 kg) horizontally. The test is repeated 3 times – each time with a new blade – along the same line.
The result: Passed. This test can't be performed on a Prowler Proof Diamond design security screen. The blades would be unable to move. The test is designed for stainless steel security screens...it goes without saying that Prowler Proof ForceField® passed easily.
Your benefit: A potential intruder would need to arm himself with much more than a knife or a heavy duty trimming knife with 3 fresh blades to shear his way past a Prowler Proof Diamond design security screen. The outcome is certain: the knife wouldn't survive.
