Kalibrointilaboratorioa

Kalibrointilaboratorioa is a facility specialized in the calibration of measuring instruments to ensure accuracy, reliability, and traceability of measurements. It may operate as an independent entity or as part of a manufacturing company, an research institution, or a government metrology service. The primary function is to compare instruments against reference standards under controlled environmental conditions and to adjust devices as needed to align their outputs with known values.

Core activities include selecting and maintaining reference standards, performing calibrations across quantities such as length, mass, temperature, electrical quantities, time, and pressure; assessing measurement uncertainty; establishing calibration intervals; and issuing calibration certificates that document the results, methods used, and traceability chain to SI units. Laboratories often store their calibration data in a metrology management system to support traceability and audits.

Quality and accreditation: The work is typically performed according to international standards, notably ISO/IEC 17025, and the lab may seek accreditation from national or regional accreditation bodies. Accreditation confirms competence to perform specific calibrations and ensures traceability to national metrology institutes and international measurement systems through the ILAC MRA.

Impact: Calibration laboratories support quality assurance, regulatory compliance, and product safety across sectors such as manufacturing, healthcare, electronics, and energy. Clients rely on calibration certificates for quality control, maintenance planning, and supply chain verification.
