G180: Providing the user with a means to set the time limit to 10 times the default time limit

Important Information about Techniques

See Understanding Techniques for WCAG Success Criteria for important information about the usage of these informative techniques and how they relate to the normative WCAG 2.0 success criteria. The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2.0.


All technologies.

This technique relates to:


The objective of this technique is to give people with disabilities enough time to complete tasks which may take them longer than someone without those challenges. Some mechanism such as a preference setting or a control on the page lets the user change the time limits to at least 10 times the default time limit. Preferably, the mechanism would have a variable adjustment that lets the user change the time limit to any value in its range, but could also provide ways to change the time limit by discrete increments. The user changes the time limit at the beginning of his session, before any activity that has a time limit.




  1. Check to see if there is a mechanism to set the time limit to 10 times the default time limit.

  2. Change the time limit to a new value that is 10 times the default time limit.

  3. Perform an action that has a time limit.

  4. Wait until the default time limit has passed.

  5. Check that the time limit does not expire until the limit specified in step 2 has passed.

Expected Results

If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been satisfied in some other way, only that this technique has not been successfully implemented and can not be used to claim conformance.
