Who Should Apply?
Is ISO/IEC 17025 Accreditation Right for Your Calibration Laboratory?
ISO/IEC 17025 is the internationally recognized standard for laboratories performing calibration activities. Accreditation demonstrates that a laboratory has the technical competence, qualified personnel, suitable equipment, appropriate environmental controls, and effective management systems required to produce accurate and traceable calibration results.
Whether your laboratory operates independently or as part of a manufacturing company, government authority, university, research institution, service company, or industrial organization, ISO/IEC 17025 accreditation provides independent confirmation of competence and strengthens confidence in the calibration certificates and results you issue.
Suitable for laboratories performing
Mass & Balance Calibration
Temperature Calibration
Pressure Calibration
Electrical Calibration
Time & Frequency Calibration
Force & Torque Calibration
Volume & Flow Calibration
Benefits
Why ISO/IEC 17025 Accreditation Matters
01
Demonstrate Technical Competence
Provide independent evidence that your laboratory has the qualified personnel, reference standards, equipment, methods, and systems needed to perform reliable calibration activities.
02
Strengthen Confidence in Calibration Results
Build confidence among customers, regulators, manufacturers, laboratories, and other users of calibration certificates by demonstrating that measurements are performed competently and consistently.
03
Establish Measurement Traceability
Demonstrate that calibration results are linked through a documented and unbroken chain of calibrations to appropriate national or international measurement standards.
04
Support Compliance & Market Opportunities
Meet regulatory, contractual, and customer requirements while strengthening your laboratory’s credibility and ability to compete for calibration work.
Assessment Areas
Key Areas Assessed During Accreditation

FAQ
Frequently Asked Questions
Common questions about ISO/IEC 17025 calibration laboratory accreditation.
What is ISO/IEC 17025?
ISO/IEC 17025 is the internationally recognized standard specifying the general requirements for the competence of testing and calibration laboratories.
Can a newly established calibration laboratory apply?
Yes. A newly established laboratory may apply when it has implemented its management system and can demonstrate that personnel, methods, equipment, traceability arrangements, and calibration activities meet applicable requirements.
What is included in the accredited calibration scope?
The scope normally identifies the measurement quantity, calibration item or instrument, measurement range, calibration method, and the laboratory’s approved calibration and measurement capability.
What is measurement traceability?
Measurement traceability is the property of a measurement result whereby it can be related to a recognized reference through a documented and unbroken chain of calibrations, each contributing to measurement uncertainty.
Is measurement uncertainty required?
Yes. Calibration laboratories are expected to evaluate and document measurement uncertainty for the calibration activities included within their scope.
Is participation in proficiency testing required?
Participation in proficiency testing, interlaboratory comparisons, or other suitable quality-assurance activities may be required where relevant and available.
How long is accreditation valid?
AAA accreditation is valid for three years, subject to continued compliance with accreditation requirements and completion of any applicable surveillance or reassessment activities.
How do I begin?
Complete the accreditation application form or contact the AAA team to discuss your laboratory’s calibration activities, measurement capabilities, and proposed scope.
