1 Jun 2012 Combined solution for vehicle test mass definition, inertia mass step-less approach, vehicle and tire selection (ICCT, Netherlands, RDW, and T&E) WLTP-DTP-10-02 2012-06-01 In 2011, the WLTP-DTP group agreed to pursue an improved definition of vehicle test mass and a step-less approach to the inertia class system. This revised document describes the current view on the combined approach for vehicle test mass, inertia setting, tire and vehicle selection. ICCT Netherlands RDW T&E
