Formal Authorization
A formal directory specifies the specific tests and calibration types a facility is authorized to perform under its ISO 17025 certification. The accredited laboratory scope defines the exact chemical analytes and matrix types (such as polyester fabric or synthetic leather) that the facility is competent to measure. External auditors verify these capabilities annually to ensure the laboratory maintains the required equipment and staff expertise.
Measurement limits and specific equipment configurations are locked to this document.
Compliance Verification
Technical assessments determine whether a laboratory can reliably detect restricted substances within the limits specified in its listing. Every accredited laboratory scope details the detection limits and measurement uncertainties for each approved method. A buyer uses this document to confirm that a mill’s chosen testing house is actually certified for the specific PFAS or azo dye test requested.
Standard Coverage
Proprietary methods or new international standards must be formally added through a surveillance visit or a desk audit. If a testing facility performs a test not found on its accredited laboratory scope, the resulting report cannot carry the logo of the accreditation body.
Global Reliability
Global brands rely on these documents to manage risk across multi-country supply chains. Failure to check the accredited laboratory scope before submitting samples often leads to invalid data that cannot support a compliance claim. The document acts as the definitive map of a laboratory’s technical legitimacy and its status remains subject to periodic review by regional bodies.
