Quality-system elements
Controls that support valid results.
The exact controls used depend on the method and quality system. These sections explain common ISO/IEC 17025 concepts in plain language.
Measurement traceability
Where applicable, results are linked through documented calibrations, reference materials, and measurement standards.
Equipment control
Critical equipment is identified, maintained, calibrated or verified, and protected from use when performance is questionable.
Personnel competence
Personnel are trained, evaluated, and authorized for the activities they perform.
Quality controls
Suitable blanks, controls, standards, replicates, system-suitability checks, or other controls are used as required by the method.
Proficiency testing
External comparisons or suitable alternatives help evaluate laboratory performance where available and appropriate.
Deviations and corrective action
Nonconforming work is controlled, investigated, corrected, and assessed for possible impact on reported results.
Document control
Current methods, procedures, forms, and records are controlled so personnel use authorized versions.
Impartiality and confidentiality
Risks to impartiality are managed, and client information is protected according to applicable obligations.
Complaints and appeals
Questions about a report or laboratory decision?
Peak Analytical should maintain documented processes for receiving, evaluating, and resolving complaints and appeals without compromising impartiality.
