PRE-SERIES TEST

A question of safety

Pre-series wheels are tested according to the demanding standards of the German TÜV and of the Japanese JWL VIA Homologation Institutes.

All tests on the wheels are made at the internal testing facilities within the OZ manufacturing facility, fully equipped with the appropriate equipment for assessment certified by TÜV and JWL VIA Institutes. OZ is authorized by these Institutes to certify wheels itself.

All OZ products are TÜV certified. The most important tests required by TÜV and JWL VIA Institutes are the Rotary bending, Rolling, Impact, and Biaxial stress tests.
