The checked purchase is EN ISO/IEC 17020:2026, whose catalogue title identifies the ISO/IEC 17020:2026 corrected version of June 2026. ISO lists the third edition as published and the 2012 edition as withdrawn. Use the 2026 reference deliberately when ordering new training or implementation support.

Translate the inspection purpose into a buying brief
The public description covers competence, impartiality and consistent operation of inspection bodies. Inspection can examine materials, products, installations, plants, processes, procedures or services and determine conformity with relevant requirements. Those requirements may originate in standards, regulations, contracts or internal specifications. Publisher’s inspection scope.
For procurement, specify the item, its condition or lifecycle stage and the question the inspection is intended to answer. Then ask the provider to identify the requirements it will use and the boundaries of its conclusion. An offer that says only “inspection to industry standards” leaves too much uncertainty about the expected deliverable.
| Decision | Question for the bidder |
|---|---|
| Item and boundary | Exactly which equipment, area, process or service will be examined? |
| Basis for the conclusion | Which named requirements and editions will be used? |
| Activities and interfaces | What site access, evidence and supporting work are assumed? |
| Report scope | Which findings and limitations will be explained to the client? |
| Independence basis | How does the proposed body describe its position under the current edition? |
Check the changed independence terminology
ISO’s public explanation says the 2026 edition changes the former A, B and C independence categories to Type A and Type non-A. It also identifies changes concerning risk-based thinking and information control. An older proposal using the three-category terminology therefore needs an explicit edition explanation. Publisher’s explanation of the revision.
Do not assign a category to a supplier from a website description alone. Ask the body and, where relevant, the intended assessment organisation how the current requirements apply to the proposed activity. This guide does not state an accreditation transition deadline or promise that every existing service must change on the publication date.
Example: buying an inspection for a refurbished installation
Imagine a facility purchasing an inspection before returning a refurbished installation to service. The facility has drawings, a maintenance history and a new contractor’s work record. One bidder prices a short visit, while another includes review of the changes and several interfaces with the operating team.
The buyer could ask both bidders to describe the same proposed inspection boundary: which parts of the installation, which records and which decision the report will support. It could also ask what would cause the report to limit its conclusion or require more information. This original comparison exposes differences in scope without prescribing an inspection method or declaring that the installation is fit for use.

Frequently asked questions
Should I buy the 2012 edition for a new 2026 project?
The checked current records point to the 2026 replacement. A legacy contract may specify an older edition, but record that contractual basis and discuss it with the relevant parties rather than treating 2012 as the latest publication.
Does the standard prescribe my product’s technical requirements?
Its focus is the inspection body. Your purchasing brief still needs to identify the applicable requirements for the item and the decision the inspection will support.
Is the correction a separate new edition year?
The catalogue keeps the 2026 designation and identifies the corrected ISO version. Confirm the supplied version; do not invent a new standard year from the correction date.
