The E-Liner FLEX ZERT is a purely electrically driven test rig for the certification of the legform impactor FLEX PLI GTR.

With the E-Liner FLEX ZERT both, the inverse test as well as the pendulum test, can be performed with highest repeatability.

During the pendulum test, the FLEX PLI GTR impactor is lifted up fully automated together with an additional weight in the legally given end position. After that it falls freely against the impact wedge.

During the inverse test a linear guided impactor is fired acc. to GTR9 to strike the pending FLEX PLI GTR impactor.

Together with the FLEX STATIC, all relevant FLEX PLI GTR certification tests are covered. Furthermore, the dynamic certification of the TRL upper and lower legform can also be performed.
