Michael Sevada from Qlab PMI testing material

To meet high standards and specific requirements, additional material testing has become indispensable within the industry. As an additional service, we provide a broad range of material testing and recertification with the best equipment and the highest standards.

Knowing an alloy’s composition and grade enables suppliers and other responsible parties to match alloy specifications to their material certificates. A PMI test is required to determine the chemical composition of a metal or alloy. PMI (Positive Material Identification) testing is a non-destructive analysis of materials.

We usually PMI test material ourselves, but sometimes, customers require PMI tests done by an ISO 17025-accredited lab. In situations like these, our partner Quality Lab provides the PMI test. Quality Lab has high professional competence and decades of experience and has been NS-EN ISO/IEC 17025 accredited since 2010.
