In cross-development projects of automobile manufacturers test reports are accepted, provided that the tests were performed by a 17025 accredited according to DIN EN ISO / IEC, independent institute. The acceptance of test reports does not imply automatic approval. Other reports may be accepted at the discretion of the customer.
Since the individual automakers make changes if necessary, work should be done according to the liabilities arising from this course work standards of the automobile manufacturers.
This course is stored as a Word file in the Department of Standardization of AUDI AG.
This course does not claim to be complete. The car manufacturers are free at any time to require the respective state of the art additional tests.
Foreword This course was developed in the present version of representatives of the automobile manufacturer AUDI AG, BMW AG, Daimler AG, Porsche AG and Volkswagen AG.
Application Warning Note Because the intended standard may differ from the draft version, may not in principle be carried out according to standard designs. If, nevertheless, a design applied in exceptional cases, so this must be agreed between the users.
