Leda-Vannaclip  have impact tested their 150NB fixed bollards at the UK’s Transport Research Laboratory (TRL) in May 2008.

Testing was carried out by TRL in compliance with Publicly Available Specification 68 (BSI PAS 68).

One key objective was for the creation of a new generation of physically smaller bollards capable of providing enhanced impact protection against terrorist-instigated hostile vehicle attacks.

A second key objective was for the bollards to provide a high degree of cutting resistance against a range of overt and covert attacks.

The tests each involved a single-sized 150NB stainless steel fixed bollard filled with a Leda-Vannaclip-designed barrier mix to strengthen it under impact and to enhance its cutting resistance. The barrier material was originally developed to combat ATM attacks in Australia.

With the bollards mounted in a shallow rigid foundation, two tests were conducted at 48km/h using, firstly a 2500kg 4x4 SUV vehicle and then a 3500kg van. A third test with a shallow embedment bollard proved ineffective in restraining the impacting vehicle, highlighting the critical importance of footing design. This event offered significant advancement to Leda- Vannaclip’s knowledge base in the area of vehicle impact testing. Further testing will be conducted in the second half of the year to further Leda - Vannaclip’s understanding of the bollards and footing interaction.
