Certification of the testing laboratory

In order to become a certified testing laboratory for TIER1 suppliers, a laboratory must first be accredited according to DIN EN ISO/IEC 17025. In a second step, a test is carried out by Deutsche ReferenzbürofürRingversucheund ReferenzmaterialienGmbH to determine suitability for the DBL 7381.10 standard. After the subsequent method test by a representative from the Mercedes-Benz Global Evaluation Center, the testing laboratory is awarded the certification and is then listed as a testing laboratory in the automobile manufacturer’s supplier system.
