Reference Material Producers
ISO 17034
Reference material producers support reliable measurement by producing reference materials with characterized properties and appropriate documentation. GTAF accreditation evaluates competence in planning, production, characterization, homogeneity, stability and certification or documentation activities within the defined 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.
Material production control
Defined production processes, facilities, equipment and competent personnel.
Homogeneity and stability
Appropriate evaluation and control of material characteristics over the intended period of use.
Characterization
Competent technical approaches for assigning property values and evaluating evidence.
Documentation and traceability
Clear documentation supporting intended use, handling, storage and measurement confidence.
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 reference materials
- Physical and material-property references
- Environmental and food-related materials
- Sector-specific reference materials
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
