ISO/IEC 17025 is an International Organization for Standardization (ISO) standard used by testing and calibration laboratories to provide a basis for accreditation of laboratory quality systems. There are many commonalities with the ISO 9000 family of standards, but ISO/IEC 17025 adds in the concept of competence to the equation, applying directly to those organizations that produce testing and calibration results.
ISO/IEC 17025 was originally known as ISO/IEC Guide 25, first released in 1978, with subsequent editions following in 1982 and 1990. Guide 25 was created with the belief that "third party certification systems [for laboratories] should, to the extent possible, be based on internationally agreed standards and procedures." In the mid- to late 1990s, an update to Guide 25 was required. However, the ISO decided to convert the guide into a standard and introduce tight compatibility with ISO 9001, which was also being revised, such that ISO 9001 would be treated as a master standard and the next evolution of Guide 25 to be treated as a standard to be specifically applied to testing and calibration laboratories.
ISO/IEC 17025:1999 was issued by the ISO in late 1999 and was internationally adopted in 2000. A second release—ISO/IEC 17025:2005—was made on May 12, 2005 after it was agreed that it needed to have its wording more closely aligned with the 2000 version of ISO 9001. The most significant changes introduced greater emphasis on the responsibilities of senior management, as well as explicit requirements for continual improvement of the management system itself, particularly communication with the customer.
At the end of November 2017, the ISO released an updated version, ISO/IEC 17025:2017. This update brought with it broader scope in sampling, testing, and calibration; a more consistent process approach; a stronger focus on information technologies; and the addition of risk-based thinking methods.
The ISO/IEC 17025:2017 standard itself comprises eight (formerly five) elements: scope, normative references, terms and definitions, general requirements, structural requirements, resource requirements, process requirements, and management system requirements. Two annexes are also included. The management and technical requirements sections of 2005 were further broken out into general, structural, resource, process, and management system requirements. The management system requirements section remains one of the more important ones, detailing the operation and effectiveness of the quality management system within the laboratory, with the process requirements being equally as vital.
The standard is organized as follows:
The scope of the standard is described over six points. It states what type of testing and calibration is covered; who it's applicable to; the purpose for the standard; what's not covered; and how it relates to ISO 9001.
This section states both ISO/IEC 17000 and the International Vocabulary of Metrology (VIM) are vital to applying the standard.
Terms and definitions
This section simply states that relevant terms found in the standard can be defined via ISO/IEC 17000 and VIM. The 2017 version added nine new terms to be defined, including "impartiality," "complaint," and "validation."
This section discusses the risks associated with creating biased results (impartiality) and risks associate with handling protected information (confidentiality) to the standard. The requirements are broken down into two subsections:
This section addresses the organization as a legal entity, responsible for its processes and actions, including the protection of customer information.
This section addresses the provisioning of resources necessary to supporting organizational operations. The requirements are broken down into six subsections:
6.3 Facilities and environmental conditions
6.5 Metrological traceability
6.6 Externally provided products and services
This section gets into the nuts and bolts of operations within the laboratory, running through best practices for various laboratory functions. The requirements are broken down into 11 subsections:
7.1 Review of requests, tenders and contracts
7.2 Selection, verification and validation of methods
7.4 Handling of test or calibration items
7.5 Technical records
7.6 Evaluation of measurement uncertainty
7.7 Ensuring the validity of results
7.8 Reporting of results
7.10 Nonconforming work
7.11 Control of data and information management
Management system requirements
The requirements for the operational effectiveness of a laboratory's quality management system are outlined in this section. It splits compliance into two options: A. complying with all of this section's subsections, or B. complying with ISO 9001:2015. The requirements are broken down into nine subsections:
8.2 Management system documentation (Option A)
8.3 Control of management system documents (Option A)
8.4 Control of records (Option A)
8.5 Actions to address risks and opportunities (Option A)
8.6 Improvement (Option A)
8.7 Corrective actions (Option A)
8.8 Internal audits (Option A)
8.9 Management reviews (Option A)
Two annexes and a bibliography are included. Annex A: Metrological traceability provides further context on section 6.5 of the standard, including addressing international agreements. Annex B: Management system options elaborates on section 8, including rationale behind the various options.
Laboratories use ISO/IEC 17025 to implement a quality system aimed at improving their ability to consistently produce valid results. It is also the basis for accreditation from an accreditation body. Since the standard is about competence, accreditation is simply formal recognition of a demonstration of that competence. A prerequisite for a laboratory to become accredited is to have a documented quality management system. The usual contents of the quality manual follow the outline of the ISO/IEC 17025 standard.
National accreditation bodies are primarily responsible for accrediting laboratories to ISO/IEC 17025. Laboratories can use either a domestic organization or some other internationally recognized body in cases where the domestic organization "has either no international recognition or where it lacks recognition in parts of the world relevant to the laboratory’s operations." Laboratories typically select a range of common and frequently used methodologies that could readily benefit and demonstrate a comprehensive quality system that those methodologies run under.
