PAS 68:2007. Dynamic Impact Test
Impact barrier: The impact conditions of the test were met with a total test mass of 1500 kg at a speed of 48km/h and at an angle of 90° to the line of the impact face.
The test was conducted with 4 Ram Bags. The bags were interconnected using 12 No: bolts threaded through webbing loops made from straps surrounding the bags. Each bag was of a triangular cross-section with walls 335mm thick and filled with water. The vehicle hit the centre of the 4-unit Ram Bag as designed and on impact, the centre two bags ruptured spraying the vehicle with water. The structure then gave way allowing the vehicle to come to a halt without major damage.
The vehicle could not be removed from the Ram Bags until the water had been mostly drained from the remaining two bags over a period of about 5-10 minutes. Penetration was zero and no debris was ejected. The following vehicle could not have passed through.
