Impact Test
The Australian Standard (AS5041-2003) simulates the effect of a human impact against a security screen and requires a security screen to withstand five single impacts of 100 joules (J) each. 100J is roughly equivalent to the impact of a young child running into a glass door. The average Australian male, weighing 86kg, can easily exert more than 100J of force in a single impact.
That’s why Crimsafe has been designed to more than just exceed the minimum requirement of Australian Standards.
The University of Queensland tested Crimsafe and competitor products for their ability to withstand single and multiple impacts. This graph shows that many competitor products could not meet the recommended Australian Standard, failing to withstand five impacts of 100J each, but Crimsafe withstood the multiple impacts required by Australian Standards, and also withstood a single impact of 550J (Crimsafe Regular), 750J (Crimsafe Ultimate) and 1200J (Crimsafe Commercial Applications).
This test is designed to simulate a knife attack on a screen, using the kind of small to medium blade favoured by home intruders.
A test screen is mounted horizontally in a rigid frame and a heavy duty trimming knife is pulled along the mesh with a force of up to 350N (35kg) and a constant downward pressure of 150N (15kg) for a distance of 250mm.
The test is performed three times along the same line with a new blade fitted each time. In order to achieve a pass, the mesh must not be penetrated in a continuous line for more than 150mm.
With our industry leading 0.9mm, 304 grade high tensile stainless steel Tensile-Tuff® mesh, all Crimsafe screens pass this test.
The specifications pertaining to the mesh and other products that we supply are our target specifications. The actual specifications for items supplied may differ, taking into account reasonable manufacturing tolerances.
