Laboratories are generally accredited to ISO/IEC 17025 by an accreditation body for a defined technical scope.

Yes. The system can be proportionate, but the laboratory must still demonstrate competence, valid methods, traceability and quality assurance for its scope.

Verification confirms that a laboratory can achieve acceptable performance when implementing an established standard method.

Validation is commonly required for non-standard, laboratory-developed, modified or out-of-scope methods.

It describes the dispersion associated with a measurement result and supports interpretation, comparability and conformity decisions.

It is the property of a result linked to a reference through a documented unbroken chain of calibrations, each contributing to uncertainty.

Through defined criteria, training, observation, practical evaluation, quality-control performance and formal authorisation.

The laboratory should use proficiency testing or suitable interlaboratory comparison where available and appropriate within a planned result-validity strategy.

It explains how measurement uncertainty is considered when a laboratory reports conformity with a specification.

Qualitcert can support scope design, method and equipment controls, uncertainty, competence, audits, management review and assessment readiness.
