General
The standard LV 124 defines the requirements, test conditions, tests for electrical, electronic and mechatronic components and systems to be used in motor vehicles up to 3,5 t. The standard is used to check the quality and safety, thus increasing the efficiency and competitiveness of the company. The tests shown are used to test a part of the component’s required properties and are not used to qualify electrical/electronic subcomponents or to qualify the manufacturing process.
One example of components are light strips, which are installed for decorative purposes in doors or on the instrument panel (I-panel).
Test procedure
The components are subjected to various environmental or mechanical loads. They are energized before, during and after the test with different operating modes. Electrical values such as current, voltage and resistance are recorded in the process. In the best case, the control system is supplied together with the specimens. This ensures that the specimens are controlled correctly and that the correct key figures are recorded. The control and the recording of the values are of course coordinated with you in advance.
Origin
As already mentioned, the electrical tests and the testing of the assemblies are carried out in accordance with the LV 124 standard, which was drafted by representatives of a wide range of automotive manufacturers (OEMs) such as Audi, Volkswagen, BMW, Porsche, Mercedes-Benz, etc. The tests described in LV 124 are included in their in-house OEM specifications (e.g. VW 80000, MBN LV124, BMW GS 95024-3-1, etc.). The aim is to minimize the risk of failure and to eliminate electrical faults that occur at short notice.
