Testing Laboratories
ISO/IEC 17025
Testing laboratories generate objective technical results used for conformity assessment, quality control, research and regulatory or commercial decisions. GTAF accreditation evaluates the laboratory’s competence, resources, methods and management arrangements within the requested scope.
Competence, impartiality and confidence
GTAF’s accreditation approach is designed to provide a structured, evidence-based evaluation of organizations performing conformity assessment activities. The emphasis is on technical competence, impartiality, consistent processes and confidence in results or certification decisions.
Technical competence
Qualified personnel, suitable facilities, appropriate equipment and technically valid methods.
Method control
Selection, verification or validation of methods and effective control of technical records.
Measurement confidence
Appropriate calibration, traceability and quality assurance arrangements where applicable.
Result integrity
Review, reporting and handling of results in a controlled and impartial manner.
Define the scope with precision
The accreditation scope should clearly describe the activities, sectors, methods, schemes or technical fields for which competence is demonstrated.
- Chemical and physical testing
- Materials and product testing
- Environmental testing
- Food, agricultural and consumer product testing
- Industrial and specialized testing
Evidence that supports reliable outcomes
Assessment considers the organization’s documented arrangements and their effective implementation. Depending on the programme and scope, evidence may include:
- Competent personnel and defined responsibilities
- Controlled procedures, records and technical methods
- Suitable facilities, equipment and resources
- Impartiality and confidentiality controls
- Quality assurance, monitoring and continual improvement
- Effective handling of complaints, appeals or feedback where applicable
