This working instruction describes

This working instruction describes the misuse testing required for the parts release process of chassis and body components of passenger and off-road vehicles under extreme conditions (special incident and misuse by the customer).Definition of “Special occurrence”:Activities with low frequency of occurrence (< 100), which can be categorized as intended use of the vehicle and neither tend to result in functional or security relevant damages nor tends to result in reduction of expected life cycle.Definition of “Misuse”:Single incidents, which don’t belong to the proper usage of the product. The functioning of the vehicle might be affected by misuse and the lifespan also might be reduced, but a defined failure mode has to occur without showing any safety risks. The rule “deformation before breakage” applies.For the release during engineering development vehicles will be tested in terms of the following criteria:• Strenght behavior• Deformation behavior• Vehicle Safety
