The VDA Recomendation 250 has been prepared by the VDA Working Group "Material Laboratory Assessment“
on behalf of the VDA Material Steering Committee to provide a tool for the standardization of
the assessment and for the improvement of the quality of material laboratory services in the automotive
The objective is the assessment of material laboratories within the companies of the automotive
industry within the framework of system auditing using a list of requirements. The application
of this Guideline is intended to save time and money and, in particular, to prevent multiple
audits by different clients.
This material laboratory assessment - which is an assessment of material laboratories according to
ISO/TS 16949 with increased depth - is intended as a basic validation. This is why suitable elements
from ISO/IEC 17025 are used in the list of requirements without however applying this
standard fully in order to keep the time and effort required reasonable. This is possible because
there is no requirement for in-house material laboratories within the automotive industry to be accredited.
