Test AI notice localization after a release

Short answer

Compare the displayed notice with the approved locale version after translation, component or routing changes. Include languages with longer text and fallback states.

When to use this guide

A release updates the English notice but leaves one locale on a shorter phrase that no longer identifies the AI participant.

This is a fictional implementation scenario. The procedure below is Article 50 Hub's suggested working method, not a prescribed legal form, a customer result or a claim that every step is an additional statutory requirement.

Review procedure

  1. Record the approved wording version for each supported locale.

  2. Test representative entry routes with browser and account language settings.

  3. Check fallback, text expansion and any mixed-language states.

  4. Record discrepancies and verify the corrected locale on the deployed build.

What the example review finds

  • One translation still refers to a previous participant type.

  • The fallback phrase omits the AI identity.

Keep these example observations separate from your own results. An unknown or untested state should stay open until the relevant evidence has been inspected.

Fields for your working record

  • Locale

  • Approved version

  • Displayed version

  • Fallback

  • Release evidence

Use the downloadable blank worksheet linked on this page to connect the observed behavior with the deployed system. Add a reviewer, date, evidence reference, unresolved questions and a next action. The worksheet is editable locally and does not upload your records to Article 50 Hub.

Completion and handoff

Close the task only for the scope actually reviewed. Preserve the result that another authorized reviewer can reproduce, identify the owner of remaining work, and record a retest when the implementation changes. A completed worksheet is not a substitute for the underlying evidence.

Decision boundary

Localization regression checks do not establish translation competence or the complete legal adequacy of wording.

The official references below provide legal or technical context. Resolve applicability and exception questions with the responsible qualified reviewer; use the product's tools to organize implementation work within that assessment.
