Official methodology to test criterion 4.13

Test 1 (4.13.1)

  1. Find the non-time-based and time-based media in the document.
  2. For each media, check that:
    • either the name, role, value, settings and status changes of the user interface components are accessible to assistive technologies via an accessibility API (for example, dynamically updated zones in a video player are correctly rendered);
    • or an alternative compatible with an accessibility API can be used to access the same accessibility features.
  3. If this is the case for each time-based or non-time-based media, the test is validated.

Test 2 (4.13.2)

  1. Find the time-based and non-time-based media in the document that have an alternative compatible with assistive technologies.
  2. For each media, check that
    • either the alternative is adjacent to the time-based or non-time-based media;
    • either the alternative is accessible via a link or an adjacent button;
    • or there is a mechanism for replacing the time-based or non-time-based media with its alternative.
  3. If this is the case for each time-based or non-time-based media, the test is validated.
