Who developed ISO 17025?

ISO 17025 is an internationally recognized standard that specifies the general requirements for the competence of testing and calibration laboratories. It plays a crucial role in ensuring the accuracy and reliability of test results that laboratories generate. In this article, we will explore the origins and development of ISO 17025.

The International Organization for Standardization (ISO)

The ISO is an independent, non-governmental organization that develops and publishes international standards. It was established in 1947 and has its headquarters in Geneva, Switzerland. The ISO's mission is to facilitate international cooperation and the exchange of goods and services by providing common standards.

ISO/IEC Guide 25: The Beginning

In the late 1970s, there was a growing need for harmonized laboratory accreditation across different countries. To address this, ISO established a technical committee called ISO/TC 176. One of the first projects undertaken by this committee was the development of ISO/IEC Guide 25, which provided general guidelines for the accreditation of testing and calibration laboratories.

The Birth of ISO 17025

In 1999, ISO/IEC Guide 25 was completely revised to meet contemporary laboratory practices, and it was renamed ISO/IEC 17025. The revision process involved input from experts, industry stakeholders, and national standards organizations from around the world. The aim was to develop a more comprehensive and user-friendly standard that would ensure the consistency and reliability of test results produced by laboratories.

ISO 17025 not only addresses the technical aspects of laboratory operations but also includes requirements related to quality management systems. This ensures that accredited laboratories have robust processes in place to continuously improve their operations and deliver accurate and reliable test results.


ISO 17025 is the result of international collaboration and years of development. It has become the benchmark for laboratory competence worldwide, providing a framework for laboratories to demonstrate their technical capabilities and commitment to quality. Accreditation according to ISO 17025 not only enhances the credibility of laboratories but also facilitates global acceptance and recognition of test results.

With continuous advancements in technology and evolving laboratory practices, ISO 17025 will likely continue to be revised and refined to meet future needs. The ongoing development and implementation of this standard play a vital role in ensuring the accuracy and reliability of test results generated by laboratories across various industries.
