Validation & Verification Bodies
ISO/IEC 17029 • ISO 14065

Validation and verification bodies provide independent evaluation of claims, assertions or information against defined criteria. GTAF accreditation focuses on competence, impartiality, evidence-based conclusions and robust processes for validation and verification activities.

Applicable framework: ISO/IEC 17029 • ISO 14065

Programme Focus

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.

Evidence-based evaluation

Defined criteria, competent personnel and systematic review of objective evidence.

Impartiality safeguards

Processes for identifying and managing impartiality risks throughout the engagement.

Consistent conclusions

Controlled planning, sampling, review, technical evaluation and reporting.

Sector competence

Appropriate technical expertise for the sectors, schemes or programmes within scope.

Typical Scope Areas

Define the scope with precision

The accreditation scope should clearly describe the activities, sectors, methods, schemes or technical fields for which competence is demonstrated.

Greenhouse gas and climate-related information
Environmental and sustainability claims
Organizational, project or product-related assertions
Other eligible validation and verification programmes

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
