Safeguard's Insurance Approved Grille

As well as being an ISO 9000 accreditation body, the LPCB also tests security grilles in its own testing facilities. These tests are intended for use in conjunction with the rules and regulations of the Association of British Insurers and Lloyd's of London for insurance purposes.

LPC1 System

Safeguard's LPC1 grille has successfully undergone a simulated attack by an opportunist burglar using a variety of tools that can all be concealed about his person. This form of attack would represent virtually all domestic and commercial burglaries.

The attack is in two parts:

A soft body impact attack test

  • which is a laboratory method of simulating shoulder blows or kicking as a means of gaining forced entry.


A manual intervention test

  • which is a manual attempt at gaining forced entry with the aid of tools.

The attack tools used are as follows:

  • Non Tool
    • 1 Soft body impactor - 30k
  • Prime Kit
    • 1 Screwdriver - 6.5mm/square x 150mm long
    • 1 Knife - blade 125mm long x 3mm thick
    • 1 Lever - 0.7kg/300mm long
    • 1 Glass cutter

  • Additional
    • Tweezers
    • Hooks
    • Pliers (including self gripping) - selection 200mm long
    • Spanners - selection 150mm long
    • Hexagon wrenches - selection 120mm long
    • Punches
    • Rope
    • Wire
    • Adhesive tape
    • Flexible plastic coupon
    • Wood/plastic wedges

Although designed to simulate an actual attack, the test is arguably much more severe than in reality because:

  • It is carried out by two experienced engineers

  • They have extensively studied drawings and the actual test sample prior to testing

  • The test is conducted in laboratory conditions

    • Well lit
    • Dry
    • Warm
  • All the tools are to hand and can be used in combination
  • They can take it in turns to attack the system and have rests between attacks
  • The tester is allowed a one minute attack over a ten minute period for each chosen method and area of attack
  • In real life the burglar would be attacking through glass and the system would be secured behind a window or door frame
  • Finally, there is no need to be quiet and no fear of being discovered
