PD CEN/TS 16786 establishes test methods for whole Truck Mounted Attenuator systems (TMAs) under impact.
PD CEN/TS 16786 specify the performance classes, impact test acceptance criteria, and test performance
PD CEN/TS 16786 on truck-mounted attenuators is relevant to:
Truck Mounted Attenuators (TMAs) are designed to protect occupants from impacting passenger motor vehicles from impacts with the rear of stationary or slow-moving mobile carriers used in work zones and during maintenance operations. During an impact with a TMA, the mobile carrier is accelerated forward as the impacting vehicle is decelerated. This can, in turn, pose a risk to road workers in front of the support vehicle.
PD CEN/TS 16786 provides guidance on test parameters, test site, test vehicles, test matrix, accuracies and limit deviations of impact speeds and approach angle, photographic coverage, evaluation criteria.
PD CEN/TS 16786:2018 aims to conduct impact testing of whole TMA systems to establish the severity of an impact with the whole system, and to establish the trajectory of the impacting vehicle and mobile carrier following the impact.
