Viidestandardid

Viidestandardid is a term used in Estonian standardization and metrology to refer to a defined set of reference standards. These are standards that laboratories, manufacturers, and certifying bodies designate as authoritative benchmarks for calibration, validation, and comparability of measurements. The concept emphasizes traceability to recognised measurement units and agreed procedures.

Governance and selection: Viidestandardid are identified by national or international standardization bodies or by accreditation schemes. Selection criteria typically include relevance to the field, stability over time, documented uncertainty, availability, and the ability to maintain an unbroken chain of custody to SI units or other primary standards. They are periodically reviewed and may be updated or superseded as knowledge and technology advance.

Applications: In testing and calibration, references from the viidestandardid set are used to calibrate equipment, validate methods, and interpret results. They underpin conformity assessment, quality management systems, and interlaboratory comparisons. Common types of reference standards include standard reference materials, reference measurement procedures, and certified reference data.

Relation to other terms: Viidestandardid are distinct from general standards (standardid) because they function as traceable references rather than normative requirements. Their use is documented in test reports, calibration certificates, and metrology documentation; they enable comparability across organizations and over time.
