Accreditation for Testing Laboratory

ISO/IEC 17025 specifies the general requirements for the competence to carry out tests and/or calibrations, including sampling. It covers testing and calibration performed using standard methods, non-standard methods, and laboratory-developed methods.


Accreditation requires that the Testing Laboratories must conform to the most recent version of the following standards:
• ISO/IEC 17025 - General requirements for the competence of testing and calibration laboratories
• Demonstrated Technical Competence specific to the field in which Testing is performed
• Relevant Requirements for ACCB Accreditation


ISO/IEC 17025 is for use by laboratories in developing their management system for quality, administrative and technical operations. Laboratory customers, regulatory authorities and accreditation bodies may also use it in confirming or recognizing the competence of laboratories. ISO/IEC 17025 is not intended to be used as the basis for certification of laboratories.

It is applicable to all organizations performing tests and/or calibrations. These include, for example, first-, second- and third-party laboratories, and laboratories where testing and/or calibration forms part of inspection and product certification.
