About the ISO/IEC 17025 Resource Center

The ISO IEC 17025 Resource Center website is a unique source of information specific to the ISO/IEC 17025 standard and ISO 17025 laboratory accreditation. The information and documents provided on this site have been donated to benefit others in understanding what ISO 17025 is all about. This information will be of benefit to laboratories on the road to becoming accredited or to customers of laboratories in understanding the benefits of an ISO 17025 accreditation.  



The ISO/IEC 17025 international standard was recently revised in 2017.


Addition of processes rather than procedures, risk based thinking and management, identifying opportunities in business, quality and customer satisfaction, measured performance, prevention of negative impacts, effective improvements, separated technical and Management System Records.  

Risk based thinking applied in this version enables some reduction in prescriptive requirements and their replacement by performance based requirements. There is more latitude on how laboratories can implement the standard. For example, ISO/IEC 17025:2005 stated "the laboratory shall have policies and procedures to ensure protection of confidential information" and ISO/IEC 17025:2017 states "the laboratory shall ensure the protection of confidential information...". This can be accomplished with policies and procedures if the lab prefers or by evidence of records such as training, internal audit, etc.  

The laboratory needs a plan to address risks, however, there is no requirement for a formal risk management system or documented risk management process.
