materiaalaudit

Materiaalaudit is a systematic assessment of the materials used in manufacturing to verify conformance with technical specifications, regulatory requirements, and sustainability criteria. The audit examines the quality and supply risk of raw materials, components, and packaging, as well as the traceability of material data throughout the supply chain.

Scope includes material certificates and test data (CoA), chemical composition and impurity levels, hazard classification, storage and handling, shelf life, packaging integrity, and recyclability. It also evaluates supplier performance, documentation integrity, and the ability to trace materials from supplier to finished product via lot numbers and BOM or ERP records.

Process typically involves planning, data collection, on-site inspections, material sampling and laboratory testing where needed, and documentation review. Non-conformities are recorded, root causes analyzed, and corrective actions requested and tracked to closure. The audit may be conducted as a supplier audit, a production-material process audit, or a combination.

Standards and frameworks commonly referenced include ISO 9001 for quality management, ISO 14001 for environmental management, industry-specific requirements such as IATF 16949 for automotive, and chemical compliance standards like REACH and RoHS. Audits often leverage risk assessment tools and traceability systems (ERP, RFID, barcode).

Outputs typically include an audit report, a list of non-conformities, corrective-action requests, and supplier performance scores. Benefits include improved material quality and compliance, reduced supply disruption, better traceability, and strengthened sustainability performance. Challenges include access to complete material data, supplier cooperation, and keeping up with evolving regulations.
