ISO/IEC 17025 establishes a global standard for instrument calibration and testing. It specifies the general requirements for the competence to carry out tests and/or calibrations. Laboratories use ISO/IEC 17025 to implement a quality system aimed at improving their ability to consistently produce valid results and is applicable to all laboratories regardless of the number of personnel or the extent of the scope of testing and/or calibration activities.
Initially issued in 1999, ISO/IEC 17025 was revised in 2005 (ISO/IEC 17025:2005). The second version better aligned 17025 with ISO 9001.
Basic to the ISO/IEC 17025 standard is the requirement for continual improvement. Regularly scheduled internal audits identify opportunities to make testing or calibrating improvements. Laboratories are also expected to remain up-to-date on scientific and technological advances in relevant areas.
Tektronix ISO/IEC 17025 Accreditation
All Tektronix quality systems meet or exceed the requirements ISO/IEC 17025:2005. The scope of the quality system encompasses all operations that affect the quality of our ISO/IEC 17025 calibration service — equipment, personnel, calibration procedures and reporting. An ISO/IEC 17025 calibration is a more thorough and precise than a ANSI Z-540.1 calibration.
A laboratory's certification to ISO 9001 alone does not demonstrate the competence of the lab to produce technically valid data and results to the same level as an ISO/IEC 17025 accreditation. Our ISO/IEC 17025 accreditation assures our clients precise, accurate and repeatable results. Tektronix ISO/IEC 17025 accreditation encompasses both our on-site and regional calibration laboratories.
Laboratories compliant with ISO/IEC 17025 guidelines may be accredited by an internationally recognized external body. This accreditation recognizes capability and competence of a laboratory to perform specific tests and calibrations. There are numerous accreditation bodies serving different regions around the world. A few of the accreditation bodies include:
- China National Accreditation Service (CNAS)
- Dutch Accreditation Council (RVA)
- German Accreditation Service GmbH (DAKKS)
- National Association of Testing Authorities (NATA)
- The National Voluntary Laboratory Accreditation Program (NVLAP)
- Standards Council of Canada (SCC)
The first step for a laboratory to become accredited is to create and implement a documented quality management system. The quality manual documents the system and normally follows the structure of the ISO/IEC 17025 standard. A rigid on-site assessment process includes staff interviews, demonstration of selected calibration or tests, evaluation of compliance and examination of lab equipment and calibration records. Upon approval, a scope of accreditation is issued.
