Conformity assessments in materials testing: an overview

Conformity assessment in materials testing is a subject of central importance, even if it initially appears complex and difficult to approach. Working with the underlying standards requires an understanding of their specific terminology and systematic structure. This precision is essential to avoid misunderstandings and make reliable, traceable statements of conformity.

W.S. Werkstoff Service GmbH operates an accredited testing laboratory and an accredited inspection body. We also carry out damage analyses and provide expert assessment services. Our personnel hold certificates in various destructive and non-destructive materials testing methods (NDT).

Against this background, companies and technical professionals need a clear understanding of the meaning and practical significance of conformity assessments – testing, inspection, certification and accreditation. It is equally important to know the relevant rules and standards and understand the expectations of suppliers, customers and other stakeholders.

Why conformity assessments are indispensable

A key conclusion of the series is that conformity assessment is far more than a formal process. It provides the basis for trust in products, processes and organisations. The level of confidence generated varies according to the procedure chosen, from a supplier’s declaration to independent certification. At the same time, increasing complexity places greater demands on the competence, independence and systematic approach of the assessment.
