ISO/IEC 17025 General requirements for the competence of testing and calibration laboratories is the main ISO
standard used by testing and calibration laboratories. Originally known as ISO/IEC Guide 25, ISO/IEC 17025 was
initially issued by the International Organization for Standardization in 1999.
The ISO/IEC 17025 standard itself comprises five elements that are Scope, Normative References, Terms and Definitions,
Management Requirements and Technical Requirements. The two main sections in ISO/IEC 17025 are Management Requirements
and Technical Requirements. Management requirements are primarily related to the operation and effectiveness of the
quality management system within the laboratory. Technical requirements includes factors which determines the correctness
and reliability of the tests and calibrations performed in laboratory.
ISO/IEC 17025:2005 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.
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.
