Compatible is not the same as certified

Three different questions

Compatibility asks whether a device works in a defined setup. Platform certification asks whether it passed a vendor programme. Regulatory compliance asks whether it meets market-access requirements. None of these labels should be substituted for another, and a single page on a website rarely distinguishes them clearly.

For procurement, the useful question is narrower than any of these labels: what exact configuration was tested, by whom, on which date and against which version of the software?

What compatibility evidence looks like

Compatibility evidence is a configuration record, not a logo. The record should identify the product revision, the operating system and build, the meeting application and version, the connection method and the firmware that was tested.

When any part of that stack changes, the evidence is technically stale. A configuration tested last year on an older operating system still tells you something, but it should be re-validated before you rely on it at scale.

• Exact product and hardware revision
• Operating system and build
• Meeting application and version
• Connection method and cable
• Firmware version and test date

What certification actually requires

Certification is granted by a vendor or standards programme and is usually recorded in a formal listing, certificate or letter. The owner of that programme, the covered products and the validity period are part of the evidence.

Phrases such as certified-ready, certification pending or certified-compatible are status claims, not certification. If the listing does not name your product revision, the certificate does not cover it.

Regulatory compliance is market-specific

Compliance depends on the target market: radio functions, power supply, electromagnetic compatibility, packaging and labelling all matter. A device that is compliant in one market may not be in another.

Ask for the certificate or declaration that names the legal manufacturer, the exact model, the covered markets and the validity period. Market-specific evidence cannot be generalised from a partner region.

Ask for the evidence trail

Request the same evidence from every vendor so answers can be compared. Keep the replies together with the purchase record, because the evidence trail is what you will need during installation and audits.

• Tested operating systems and application versions
• Connection method and hardware revision
• Certification listing or report reference and its owner
• Countries and configurations covered
• Dates of testing and evidence review

Keep a living evidence register

Procurement teams should maintain a short register for each model: the claim, the supporting record, the review date and the next review date. When firmware, hardware, operating system or application versions change, the affected rows are retested.

• Claim and supporting record reference
• Review date and owner
• Next scheduled review
• Retest triggers and results

Common pitfalls

Most problems come from treating a marketing label as evidence: a platform logo used as proof of compatibility, a status phrase read as certification, an expired listing kept on a product page, or an older configuration quoted as the current one.

None of these are deliberate deception in most cases; they are the natural result of content that is not reviewed. A short, dated evidence register removes the ambiguity.

• A logo used as proof of a configuration test
• Status phrases presented as certification
• Expired or superseded listings
• Evidence for one region applied to another

Record pending states honestly

A public roadmap may say evaluation or testing is pending. It should not use phrases that resemble certification until the relevant organisation has granted that status.
