This article discusses the test methods found in eight technical annexes to proposed regulations being examined by the European Committee for Normalization (CEN) Technical Committee (TC) 226, Working Group 1 (WG1), which is concerned with the standardization of safety barriers, crash cushions, and, in a general way, road restraint systems. These annexes describe the test specifications a little further. They include how-to methods of measuring the acceleration severity index (ASI), theoretical head impact velocity (THIV), post-impact head deceleration (PHD), and vehicle compartment deformation index (VCDI). They also include how to compensate for instrumentation displaced from a vehicle's center of gravity, a test report from an International Standardization Organization (ISO) proposal that is very detailed, how to measure kinetic energy and average force, some measurement techniques for compensating for different locations of axle loads on the vehicles, etc.
