mittaustarkastuksia

Mittaustarkastukset, also known as measurement audits, are systematic evaluations of measurement systems, instruments, and procedures to ensure they meet predefined accuracy, precision, and reliability criteria. The principal aim of a mittaustarkastus is to verify that measurement practices produce trustworthy data for decision making, quality control, and regulatory compliance.

Companies in regulated industries such as pharmaceuticals, automotive, and environmental monitoring routinely conduct mittaustarkastuksia. National standards bodies, for example Finland’s SFS and the European Committee for Standardization (CEN), provide guidelines that align with ISO 9001 and ISO/IEC 17025 for testing and calibration laboratories. Audits typically involve traceability checks, bias analysis, reproducibility studies, and calibration record reviews. Tools like statistical process control charts and the Gage R&R method are commonly employed to assess measurement variability.

There are two main types of mittaustarkastuksia: internal audits, carried out by an organisation’s own quality department, and external audits, performed by independent certification bodies or regulatory authorities. External audits can lead to certification of compliance with specific standards or to required corrective actions.

By maintaining rigorous measurement audits, organisations safeguard product quality, protect consumer safety, and meet legal and contractual obligations. Continual improvement of measurement systems, guided by audit findings, is regarded as a best practice in modern quality management systems.
