What is ISO/IEC 17025?

ISO/IEC 17025:2017 is the international standard that outlines the general requirements for the competence of testing and calibration laboratories. Developed by the International Organization for Standardization (ISO) in cooperation with the International Electrotechnical Commission (IEC), ISO 17025 is recognized globally as the benchmark for laboratory quality and competence.

It applies to all laboratories performing testing, sampling, or calibration and is essential for labs seeking accreditation and recognition for the accuracy, consistency, and reliability of their results.

Why ISO 17025 Accreditation Matters

ISO 17025 accreditation is more than just a certificate—it’s a signal of technical competence, data integrity, and global credibility. Laboratories accredited to ISO 17025 standards can:

  • Demonstrate valid and traceable results

  • Ensure customer confidence and satisfaction

  • Facilitate acceptance of test results internationally

  • Improve laboratory efficiency and risk management

  • Meet regulatory and contractual requirements

Whether you’re operating in healthcare, environmental testing, food safety, pharmaceuticals, forensics, or industrial inspection, ISO 17025 is the gold standard for lab quality systems.

Key Elements of ISO/IEC 17025:2017

1. Scope

Defines the range of testing, calibration, and sampling services to which the standard applies.

2. Normative References

Specifies other ISO documents that are referenced within the standard.

3. Terms and Definitions

Clarifies key terminology for consistent interpretation and implementation.

4. General Requirements

Focuses on impartiality and confidentiality, ensuring that lab activities are free from conflicts of interest or undue influence.

5. Structural Requirements

Outlines the responsibilities and authority of laboratory management and organizational structure, ensuring accountability and clarity.

6. Resource Requirements

Addresses the personnel, facilities, equipment, and support services needed to ensure technically valid results.

7. Process Requirements

Includes procedures for:

  • Handling test and calibration items

  • Method validation

  • Measurement uncertainty

  • Sampling, traceability, and data integrity

  • Reporting results and managing complaints

8. Management System Requirements

Allows for either:

  • A traditional QMS based on ISO 9001, or

  • A standalone management system that meets all ISO 17025 clauses

ISO 17025 vs ISO 9001: What’s the Difference?

Feature ISO/IEC 17025 ISO 9001
Focus Laboratory competence Quality management
Industry Testing and calibration labs All industries
Technical Validation Required Not required
Accreditation By national accreditation bodies Certification by registrars
Use Case Demonstrating lab results’ accuracy Improving overall quality management

ISO 9001 focuses on process quality, while ISO 17025 goes further to verify that test results are scientifically valid and reproducible.

How to Get ISO 17025 Accreditation

  1. Understand the Standard
    Read and study the ISO/IEC 17025:2017 standard to fully grasp its requirements.

  2. Conduct a Gap Analysis
    Compare current practices against the ISO 17025 requirements to identify deficiencies.

  3. Implement a Quality Management System (QMS)
    Establish or upgrade your lab’s QMS to comply with ISO 17025.

  4. Train Personnel
    Ensure all staff understand procedures, policies, and their responsibilities under ISO 17025.

  5. Document Everything
    Maintain records of procedures, calibration, training, audits, and corrective actions.

  6. Internal Audit and Management Review
    Perform internal audits and hold regular reviews to ensure ongoing compliance.

  7. Apply for Accreditation
    Contact an ISO 17025 accreditation body (such as A2LA, IAS, or SCC) to begin the assessment process.
