ATEX harmonised standards: start with the complete reference
The European Commission's harmonised-standards overview explains their European standardisation context and Official Journal publication. It also states that their use is voluntary: another technical solution may demonstrate compliance with mandatory legal requirements. Voluntary standards do not make the underlying legal obligations optional.
For a purchasing review, copy the designation exactly as supplied, including its prefix, part number, year and any amendment. Keep the original document beside the transcription. Avoid shortening the reference in a way that removes the very distinction under review.
Suppose a quotation names one reference while a declaration names another. Record both, identify their document sources and ask the responsible party to explain the relationship. Do not silently replace either entry with a newer-looking number. The task is to understand the evidence, not to make the paperwork look consistent by editing it.
A summary list is a starting point, not the final record
On the review date, the Commission's ATEX standards page lists Official Journal publications and amendments. It warns that its summary includes both references still supporting a presumption of conformity and references already withdrawn. The summary is informational, may contain errors or omissions and does not itself create legal effects.
Accordingly, treat a search hit as a lead to inspect, not a conclusion to forward. Retain the applicable official publication identified through the Commission page, together with the precise reference and any qualifications the responsible reviewer considers relevant. If the underlying record cannot be opened, mark that check incomplete.
A downloaded spreadsheet also needs context. Record where it came from and when it was retrieved. A file renamed current-standards on a shared drive can outlive the review that produced it. Its convenient name is not a substitute for a recorded source and review date.
Keep four evidence records distinct
| Record | Question it helps answer | Unsupported shortcut |
|---|---|---|
| Supplier's standard reference | What designation is actually claimed? | Correcting its year without clarification |
| Official citation record | What does the relevant publication say? | Treating a summary search hit as the complete check |
| Product documentation | Which offered item and claim are addressed? | Treating a cited standard as a model certificate |
| Project review decision | Who assessed the evidence and open questions? | Treating receipt of an attachment as acceptance |
This is an editorial record-management aid, not an ATEX conformity-assessment procedure. The four records should be connected, but one should not be used to disguise the absence of another.
Assign different dates to different questions
A document set may contain a publication date, an issue date, a review date and a delivery date. Write what each date describes before using it to make an acceptance decision. A single spreadsheet column called expiry is a poor place to combine unrelated information.
Where a reviewer identifies a date-dependent citation issue, retain the exact supporting record and the explanation of its relevance to the offered item. Ask whether the question concerns the standard reference, the manufacturer's evidence or a contractual requirement. Those questions may need different respondents.
The existing EN IEC 60079-28:2026 update guide addresses one specific optical-radiation standard change. This article instead explains how to organise a citation check across an enquiry. It does not announce a new standards amendment or transfer that earlier example's dates to other references.
Connect the citation check to the actual offer
Write the offered model and configuration at the top of the review record. Beneath it, list the documents that the supplier says support the claim, keeping their own identifiers intact. An index should help the reviewer retrieve evidence, not become a shortened substitute for that evidence.
Separate a missing attachment from an unresolved technical judgement. For example, a declaration may be absent from the package, or it may be present while its relationship to the quoted variant remains unclear. These are different follow-up questions and should not receive the same generic documents pending label.
Use the IECEx and ATEX document verification guide for the separate product-document review. The Ex nameplate guide helps organise marking information. Neither exercise can be replaced by finding a standard title on a public website.
Preserve the question when an offer changes
When a supplier revises the quotation, compare the identity of the offered item with the identity recorded at review. Keep the previous version available so the responsible reviewer can see what changed. Do not assume that an earlier acceptance note covers a new suffix, option or document issue.
A useful handover states the exact unanswered question, its document reference and the person expected to respond. For instance, ask which supplied document explains the difference between two cited references. That is more actionable than requesting a general assurance that everything is compliant.
Close the record only with the responsible team's stated outcome. If the answer is conditional or a matter remains open, preserve that qualification when the purchasing file is passed to another department. The checklist here is intended to prevent administrative ambiguity, not to make the technical or legal judgement for that team.
