A loading standard called CARLOS TC BC (CAR LOading Standard for Trailer Coupling devices with Bike Carriers) is derived with focus on trailer coupling devices during bike carrier service. Based on this new standard a comparison with available loading standards for trailer coupling devices is performed and an optimized design of a trailer coupling device is proposed. The derived loading standard is based on results of a public opinion poll in 2005 with 1200 trailer coupling device users. Furthermore service load measurements at trailer coupling devices on proving grounds and public roads are used to derive the loading standard. The scatter bands caused by the track mixture (T), the way of driving (F) and the loading conditions (B) are taken into account to carry out the standardization process. Comparisons between loading standards CARLOS TC BC, CARLOS TC and 94/20/EC are performed. The regulation 94/20/EC covers fictitious damage sums of CARLOS TC BC and CARLOS TC for large sections of the trailer coupling device. However the regulation 94/20/EC does not lead to service load oriented stresses and strains, so that it is not used within the derivation of an optimized trailer coupling device.
