The United Nations Economic Commission for Europe (UN ECE) on Jan. 4 published the 03 series of amendments to Regulation No. 29 on commercial vehicle cab safety which introduces some significant amendments to the pendulum impact test procedures, according to InterRegs, an online resource for global vehicle safety and emissions regulations. The changes increase the impact energy level for the existing front pendulum impact test from 44 kJ to 55 kJ, specify an additional front pendulum impact test designed to test the cab’s A-pillars, and require that the cab roof be subjected to a lateral pendulum impact prior to the roof crush test being conducted. Compliance with these new requirements becomes mandatory for new types of truck from Jan. 30, 2017.
