ISO/IEC 17025:2017 Testing and Calibration Laboratories

ISO and the International Electrotechnical Commission (IEC) developed a joint documents used by testing and calibration laboratories. Most Regulatory Authorities across global will not accept test or calibration results from a lab which is not accredited, so labs must hold ISO/IEC 17025 accreditation in order to be reckoned technically competent. There are many commonalities with ISO 9000 standard but ISO/IEC 17025 evaluates the technical competence in the lab testing and calibration services emphasises mostly in competence requirements and directly deals to organizations that produce testing and calibration results. ISO/IEC 17025 was initially issued in 1999 by the International Organization for Standardization and second issue released on 2005, but third edition replaced it with following main changes:

  • Greater flexibility in the processes requirements, responsibilities of organization and documented information;
  • Applied Risk-based thinking minimized in prescriptive requirements and replacement by performance-based requirements;
  • Laboratory definition added.

ISO/IEC 17025 standard comprises:

  1. Scope
  2. Normative References
  3. Terms and Definitions
  4. Management Requirements
  5. Technical requirements

The later are two main sections in ISO/IEC 17025 in relation with operation and effectiveness of the QMS within laboratory and factors determining correctness and reliability of the tests and calibrations performed in the laboratory.

How to achieve ISO/IEC 17025 accreditation?

– Laboratory’s QMS and Technical competence evaluation;

– Conducted audits;

– Meeting management requirements and Technical Requirements of ISO 17025

– Regular Internal Audits to ensure continual improvement


GSC helps you to obtain ISO 17025 Accreditation proving that laboratory operating with an acceptable QMS having the ability and competence to provide testing and calibration results.

It proves that tests performed in your laboratory are against the international standard of ISO 17025 and results accepted mutually by government and regulatory organizations.

It proves that unlike most QMS ISO Standards, third party assessment of the laboratory is carried out by the Accreditation Body, therefore Accredited under ISO/IEC 17025 rather than Certified or registered ISO 9000 series.

So, accreditation by GSC affirming to technical competence within your laboratory in addition to documented quality system operation specific to a scope of Accreditation.
