PAS 68 performance ratings can, at first, seem confusing. If you break each section down, it becomes a lot simpler. As an example, here is the performance rating of our PAS 68 Hydraulic Road Blocker: PAS68: V/7500[N2]/80/90:0/25
The ‘V’ standards for a vehicle. This first section of the rating is stating which test method has been used, and in this case, the road blocker has been crash tested using a vehicle. Sometimes you might also see a rating start with either a ‘D’ for design, where the test is stimulated or ‘P’ for a pendulum. However, the vehicle impact testing is most commonly used as it clearly replicates dynamic, real-life conditions.
