Road vehicles. Trailers up to 3,5 t. Calculation of the mechanical strength of steel drawbars Ingestion-build-50790 Quality Management Systems1 Scope This International Standard gives a simplified procedure for the calculation of the mechanical strength of steel drawbars, whether there are welds or not, for centre axle trailers Categories O1 and O2 as specified in the UNECE, Consolidated Resolution on the Construction of Vehicles (R. E. 3). Consequently, it only applies to simple constructions that enable a calculation in bending.
