What is ISO/IEC 17025?
ISO/IEC 17025 is the international standard that sets the requirements for the competence, impartiality and consistent operation of testing and calibration laboratories, and on which laboratory accreditation is based.
The current edition is ISO/IEC 17025:2017; the standard was reviewed and confirmed unchanged in 2023. ISO’s introduction page states one benefit of the standard plainly: results from accredited laboratories can be accepted across countries without retesting. For an exporter, this is exactly where the standard’s value lies: a test carried out in an accredited laboratory in Turkey may not have to be repeated in the buyer’s country.
Can a laboratory be “17025 certified”?
The correct word is not “certified” but “accredited”. A laboratory does not receive a certificate from a certification body; an accreditation body assesses it for specific tests and methods and accredits it. Accreditation therefore belongs not to the laboratory as a whole but to the tests within its scope: the same laboratory can be accredited for one test and unaccredited for another.
This distinction also shows in the report. According to TÜRKAK’s guidance on test reports and calibration certificates, tests outside the scope of accreditation are marked in the report; the verification QR code on calibration certificates is also printed only on certificates within the accredited scope. Not every result in a report is accredited; the marking tells you which one is.
How is 17025 mentioned on a manufacturer’s site?
With the laboratory’s name and accreditation number, as a property of the test, not of the product: “this property was measured by this method in this accredited laboratory”. Accreditation marks belong to the laboratory. Under ILAC’s rules, only accredited bodies use the accreditation symbol, and the symbol is not placed on the product assessed; TÜRKAK’s mark conditions also close the logos of international recognition organizations to certified companies. On the site, you can show the marked report in full; you cannot carry the mark over to the site as a whole or to product images (our reading).
- If your own laboratory is not accredited, a phrase like “our 17025-compliant laboratory” gives the impression of accreditation; avoid it.
- If you work with an accredited external laboratory, write its name and accreditation number; the number can be looked up in the accreditation body’s list.
- State whether the result is within the accredited scope in the report.
In Turkey, laboratories are accredited by TÜRKAK. According to TÜRKAK’s guidance, the report of an accredited laboratory contains the name of the accreditation body, the laboratory’s name and address, the TÜRKAK mark assigned to the laboratory, the report number on every page, the number of pages, the customer’s name and address, and the sample information. These fields are also the backbone of the test report record on the site: if you build the record from these fields, the buyer sees what was measured, where and when, without opening the report.
How the report is shown on the site is covered in the accredited test report guide; what accreditation is is explained in the accreditation entry.
For a site that shows your certificates as a record buyers can verify, B2B website builds and measures the certificate page, the product scope and the path to a quote together.
