Evaluating Metrological Traceability on Certificates (ISO/IEC 17025)
August 13 @ 2:00 pm – 3:00 pm
Metrological traceability is a fundamental requirement of ISO/IEC 17025 and a cornerstone of laboratory competence. Determining whether traceability has been adequately demonstrated can be challenging, given the variety of certificates a laboratory receives, including calibration certificates, certificates of analysis, and reference material certificates. These certificates carry varying levels of traceability information, and the laboratory must evaluate that information to determine whether it is suitable for its operations.
This webinar provides a practical approach to evaluating metrological traceability on certificates and determining whether the stated traceability supports the laboratory’s needs under ISO/IEC 17025. Participants will learn how to assess traceability claims, identify key supporting information, recognize potential gaps, and document traceability evaluations in a way that supports the laboratory’s management system and accreditation requirements. Real-world examples illustrate effective calibration certificate review practices and support compliance with ISO/IEC 17025 accreditation requirements.
Whether you review certificates daily or only occasionally, this webinar will help you evaluate traceability claims with greater consistency and confidence. Join us to strengthen your understanding of traceability and gain confidence in your certificate review process.
