ISO/IEC 17025 clause 8.3: keep laboratory documents current at use
Clause 8.3 requires control of internal and external documents related to fulfilling ISO/IEC 17025 under Option A. Documents include more than formal procedures: methods, specifications, manufacturer instructions, tables, charts and other relevant information may guide technical decisions and therefore need appropriate control.
What clause 8.3 requires in practice
Clause 8.3 applies under Option A and covers documents, internal and external, that relate to meeting the standard. A note explains that documents can include policy statements, procedures, specifications, manufacturers' instructions, calibration tables, charts, textbooks, posters, notices, memoranda, drawings and plans, on paper or in digital form.
The laboratory ensures six things. Authorised personnel approve documents for adequacy before issue. Documents are reviewed periodically and updated as needed. Changes and the current revision status are identified. Relevant versions are available at points of use, with distribution controlled where necessary. Each document is uniquely identified. Unintended use of obsolete documents is prevented, with suitable identification on any obsolete copy that is kept for some purpose.
The aim is that people doing the work always use the right information, and that anyone can tell which version that is.
Approve and identify the current information
Documents must be approved for adequacy before issue by authorised personnel and uniquely identified. Establish who can judge the technical and operational adequacy of each document type. Administrative formatting approval alone may not establish that a method instruction is correct.
Identify changes and current revision status. Personnel should be able to determine which version applies without guessing from filenames such as “latest” or “final”. A controlled identifier and revision method can be simple, provided it is reliable.
Review and update where necessary
Periodically review documents and update them as needed. The standard does not prescribe one universal review interval for every document. Choose arrangements suited to the document and relevant change sources, including revisions issued by external organisations.
For external methods, connect document control with clause 7.2.1's latest-valid-version and verification requirements. Replacing the stored method file is not the whole change process if technical instructions, calculations or training are affected.
Put applicable versions where work occurs
Relevant versions must be available at points of use, with distribution controlled where necessary. Consider printed copies, temporary sites, instrument workstations and offline materials. A central portal can be effective only if personnel can actually use it during the activity.
Prevent unintended use of obsolete documents. If old versions are retained for a legitimate purpose, identify them appropriately. Historical retention may be necessary to explain past work, but it should not make the old version appear current to an operator.
Why controlling laboratory documents matters
Laboratories run on instructions: methods, tables, manufacturer manuals and calculation sheets. When an outdated version is in use, the result may be wrong, and nobody may realise until a customer queries it.
Reliable document control prevents that quiet failure. It also shortens training and reduces arguments about which instruction applies. For an accreditation body, it shows that the laboratory knows what information governs its work. In a business that depends on defensible results, it is among the least expensive controls and one of the most visible to assessors who walk the floor.
How to implement clause 8.3
Begin with the documents people actually pick up at the bench, including external ones that were never formally listed. Simple methods work well here. A clear identifier, a visible revision mark and a controlled place for current copies often achieve more than an elaborate system nobody maintains.
- Walk the laboratory and note every instruction, table, chart and manual in use, internal and external.
- Decide who is competent to approve each type of document for technical adequacy.
- Give every controlled document a unique identifier and a simple revision indicator that people can read at a glance.
- Choose how current versions reach the point of use, including printed copies, instrument workstations and offline sites.
- Set a way to review documents, to watch for revisions from outside organisations and to mark or remove obsolete copies.
- Check by observation that staff are using the current version, not only that the master list is tidy.
Two illustrative document controls
A testing laboratory receives a revised published method. It evaluates the change, updates relevant instructions and removes uncontrolled old bench copies from use while preserving the historical version needed for earlier records. Staff understand when the new version becomes effective.
A calibration laboratory uses a reference table at several workstations. It ensures the approved revision is available consistently and that a locally saved old copy cannot silently continue to guide calculations. The master register is checked against actual point-of-use information.
Evidence and common mistakes
Approval, review and revision records can demonstrate control, together with checks of what personnel actually use. A master document list is an optional tool, not the entire requirement. The appropriate system may combine controlled files, publication monitoring and managed printed copies.
Avoid controlling only documents with an internal procedure number, overlooking external instructions, or assuming a read-only file is automatically current. Also distinguish documents that instruct work from records that show what happened; both need control, but their purposes and change treatment differ.
Frequently asked questions
Do external test methods need document control?
Yes. External documents relevant to fulfilling the standard are included. Control their applicable versions, availability and changes alongside the technical method requirements.
Must every document be reviewed annually?
The clause requires periodic review and updating as necessary, without prescribing one universal annual interval. Use an appropriate arrangement and meet any other applicable conditions.
Can obsolete documents be retained?
Yes, for a legitimate purpose such as understanding earlier work, provided they are suitably identified and unintended use is prevented.
Turn this requirement into reliable laboratory practice
Ask Sterling to review documents at the actual point of laboratory use, including external methods and local copies. A free consultation can identify changes that reduce wrong-version work without unnecessary administration.
