The quality of products in manufacturing or loading plants depends increasingly on reliable measuring readings from measuring instruments and their traceability to national or international standards. For this reason, the WPD has been certified according to DIN EN ISO/IEC 17025 as a testing laboratory. Testing and calibration pursuant to DIN EN ISO/IEC 17025 are required not only in the automotive industry, but also in numerous other industries, such as the chemical and petrochemical sectors.

All testing and inspection equipment used by the WPD have been traced to national standards and guarantee a high standard of measurement accuracy. Through regular internal and external audits, the WPD guarantees high quality standards for its testing facilities. The quality of the testing and inspection equipment is regularly monitored and documented in longitudinal studies.  By adhering to this method of quality monitoring, the WPD provides operators of measuring instruments with assured inspection results according to DIN EN ISO/IEC 17025.
