Official methodology to test criterion 4.10

Test 1 (4.10.1)

  1. When the document is loaded, if a sound is triggered automatically, check that
    • either the sound sequence lasts 3 seconds or less;
    • or a device (a button, for example) on the element that triggered the sound (see note), or on the page, can be used to stop it;
    • or the volume of the sequence can be controlled by the user, independently of the system volume control.
  2. If this is the case, the test is validated.

Note: the following elements are likely to trigger sounds when the page is loaded: <audio>, <video>, <object>, <embed>, <bgsound> elements or JavaScript code (using the Web Audio API, for example).
