Testing of trailer towing devices (CARLOS TC)
Testing standard:
UN ECE R55
Product information
Approval-relevant multiaxial fatigue strength test as a service load follow-up test (BLNV). Required for the approval of a trailer coupling device (AHV) on the European market. Also known colloquially as the CARLOS TC (CAR LOading Standard Trailer Coupling) test and was developed by manufacturers, the TÜV and the Frauenhofer Institute.
The realistic load application of the vertical, longitudinal and transverse forces on the AHV is carried out using a triaxial servo-hydraulic test rig. This ensures reproducible laboratory conditions. The test can be carried out on all typical AHV types (fixed, removable, swivelling, bolt, combination with electrical control).
The exact type of test is not defined in detail in the standard, so that depending on the target group (vehicle or component manufacturer) the test can be carried out on an entire vehicle or only on the AHV assembly (incl. cross member).
