Standards and testing

What is a security screen?

Not every screen that looks like a security screen actually is. There are essentially three grades of screen - security screens, fall prevention screens and barrier screens.

Security screen

Security screens must meet standards for both construction and installation in order to qualify as security screens, as well as passing stringent tests.

Fall prevention screens

Fall prevention screens do not meet the requirements of a security screen, but must comply with fall prevention standards to ensure they will withstand outward forces.

Barrier screens

Barrier screens include lightweight stainless steel mesh and steel doors that do not meet security or fall prevention standards. They are useful if you want something stronger than flyscreen, for longevity or to keep pets in.

What standards do security screens have to meet?

 

 

AS5039 sets the requirements and performance for the manufacture of all types of hinged and sliding security doors and security windows.  The screens and grilles must be able to resist attempted break-ins, and it should be very difficult to slice through a screen or penetrate a grille.

  • AS5040 sets the requirements for the installation of all types of security doors and windows. Security screens should be installed in a way that prevents an intruder prying the screen from its hinges or frame and gaining access to the house.

  • AS5041 sets out the required tests for security screen doors and windows. Key tests include the dynamic impact, jemmy, pull, probe, shear and knife shear tests.

Australian Standard  AS5041 sets out the required tests for security screen doors and windows. Key tests include the dynamic impact, jemmy, pull, probe, shear and knife shear tests. Testing must be carried out at an independent NATA accredited facility.

In addition, there are safety standards for fire, cyclones and corrosion, which are important in some areas. 

All our security screens have been rigorously tested and exceed these requirements. 

Some tests can be easily demonstrated using a dragon 🐉

Dynamic impact test

The dynamic impact test is designed to simulate an intruder trying to kick through a security door window. To pass the test, a door must withstand 5 consecutive impacts from a 40kg bag, hitting the door with a force of 100 joules. 

Knife shear test

The knife shear test determines the resistance of the security mesh to an attack from a heavy duty knife. The knife strikes the mesh a number of times with a constant force. If the knife penetrates the mesh with a cut longer than 150mm, the mesh does not pass.

Jemmy 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 fastening points. The force applied is up to 450 N (45 kg) for 20 seconds – way beyond the capability of most potential intruders

Bushfire rating

The Australian Standard for construction in bushfire zones (AS 3959) requires that openable windows are screened with corrosion-resistant steel, bronze or aluminium mesh with an opening less than 2mm x 2mm. 

All our stainless steel mesh and aluminium security screens meet this requirement and are approved up to Bushfire Attack Level 29 (BAL-29). ForceField has been tested and approved up to extreme level BAL-FZ (fire zone).

Cyclone testing

Cyclone testing is not a requirement for buildings in Brisbane, but it is reassuring to know that all our stainless steel security screens easily pass the missile test.
