ISO 17025/IEC 17025: 1999

International Organization for Standardization (ISO) 17025 (more specifically ISO/IEC International Electromechanical Commission 17025:1999) is an international standard for calibration and testing labs “General Requirements for the competence of testing and Calibration Laboratories”2.
It requires labs to demonstrate that they:

• Operate a quality system covering processes, documentation and management.
• Generate technically valid results taking account of the equipment, procedures, and personnel.

This standard is an evolution of the former ISO Guide 25. It replaces EN45001 in Europe and has been adopted in the US as an ANSI standard that provides a migration path to international standards from the older Z540-19994.

All national accreditation bodies have adopted ISO 17025 as a way to ensure standardization. Several industries or countries have incorporated it into their industry-specific or application-specific regulations.
