When making the decision to purchase a security window or door for your residence or business, it’s fair to say that it’s a reasonably sized investment.
So understandably, you want to make sure that you’re getting your money’s worth when investing in a security screen. Australian Standards aid this process in allowing you to see exactly how safe and secure security screens are.
In essence, the Australian Standard for assessing security screens are quite high, with each door having to pass a series of thorough experiments in order to pass. Even if the security screen passes all but one test, it cannot be deemed ‘Australian Standards Certified’.
The tests all security screens must undergo to be considered certified by Australian Standards are outlined below.
Australian Standards Certified Security Screens – The Impact Test
The impact test is designed to feign a physical attack, such as a shoulder barge or kick, on the security screen. A large pendulum mass is used to force such pressure onto a particular weak spot on the security screen, four times in a row. The security screen can only pass the impact test if there is no obvious signs of weakening.
Australian Standards Certified Security Screens – The Jemmy Test
The jemmy test is used to observe the performance of a security door in a simulated forced entry. This test involves placing a wedge in-between the hinges of the door and the door lock. For the screen to pass, it must hold fast when a mechanical winch is used to attempt to pry the screen open.
Australian Standards Certified Security Screens – The Pull Test
Next, the pull test must occur after the jemmy test, as there needs to be a sufficient gap or opening in the screen. Similar to the jemmy test, the pull test uses a winch to force a significant amount of pressure to the prised area. If the screen at any time gives way, it is considered an automatic fail.
Australian Standards Certified Security Screens – The Knife Test
The final test is the knife test, which is designed specifically to examine the mesh of the security screen. This examination involves a heavy duty knife being forced to cut through the meshing three times in a row. If the security screen mesh shows no cuts greater than 150mm, then the security screen has passed.
