LV 214-4 OEM Connector Test Specification

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of LV 214-4 testing. LV 214-4 is an automotive standard developed by representatives of German automakers Audi AG, BMW AG, Daimler AG, Porsche AG and Volkswagen AG.

LV 214-4 OEM Connector Test Specification

The standard outlines terminal requirements specifically for the automotive industry. The standard is for efficient evaluation of terminals by crimped force monitors. For use in an automotive wiring harness, the terminal must exhibit certain clamping force characteristics so that typical clamping force monitors can detect critical failure modes effectively. The standard has been around for many years, although it is currently in draft form and many points are still largely theoretical.

The standard focuses on the relative deviation of force curves and headroom, both of which are common concepts related to crimp force tracking. Relative deviation is the change in peak strength expressed as a percentage. The headroom is the difference between the peak strengths of the average good curl and the hollow curl curves, expressed as a percentage.

LV 214-4 defines what an empty crimp is; something that is not clear to everyone. In a good crimp, the conductor crimp is filled with all the conductor strands and the insulating crimp with all undamaged insulating materials. The tightening parameters are at the nominal values ​​specified by the manufacturer. An empty crimp has a complete insulating crimp, but the conductor crimp is empty.
