Just How Strong Is Your Security Door?

Australian-StandardsWhen you’re considering purchasing a security door or window for your home or business, it’s fair to say that they’re usually quite a big investment. Therefore aside from getting your money’s worth you want to make sure it’s going to do the job that it’s supposed to do. You might have already been doing your homework and read that a particular door was passed to Australian Standards, but what exactly does this mean. Let’s take a closer look.

In essence the Australian standards for testing security doors are relatively high and each door has to pass not just one test but a series of rigorous experiments. If a security door passes all tests bar one, it still can’t be considered ‘Australian Standards certified’. Instead each test has to be deemed successful. The tests are as follows.

Impact testing

Designed to simulate a physical attack such as a kick or a shoulder barge on the screen a large pendulum weight is used to force 100j of pressure into a certain point. This is then carried out a further four times. If the door stays intact with no obvious signs of weakening, then it’s considered a pass.

Jemmy testing

As the name suggests the jemmy test involves placing a wedge in between the door lock and hinges of the door to simulate a forced entry. A mechanical winch is then used to try and pry the door open. In order for any security door to pass, it needs to hold fast.

Pull test

A pull test can only be carried out after a jemmy test when a sufficient gap has been prised open. Again a winch forcing significant pressure is applied to the prised area. If the door holds fast it passes and if it gives way, then it’s a fail. Obviously if the jemmy test shows no prised gaps then the door will then move on to the next and final test.

Knife testing

The knife test is designed specifically to test the security meshing. This involves forcing a heavy-duty knife through the meshing. This is carried out three times and a new blade is installed for each go. In order to pass, the meshing should show no incisions greater than 150mm.
