For each time limit that is set by the content, at least one of the following is true:

Turn off

The user is allowed to turn off the time limit before encountering it; or


The user is allowed to adjust the time limit before encountering it over a wide range that is at least ten times the length of the default setting; or


The user is warned before time expires and given at least 20 seconds to extend the time limit with a simple action (for example, "press the space bar"), and the user is allowed to extend the time limit at least ten times; or

Real-time Exception

The time limit is a required part of a real-time event (for example, an auction), and no alternative to the time limit is possible; or

Essential Exception

The time limit is essential and extending it would invalidate the activity; or

20 Hour Exception

The time limit is longer than 20 hours.



The purpose of this success criterion is to ensure that users have enough time to interact with the content.

How to Meet

Authors need to ensure that users can control time limits that would prevent them from completing a task, when the time limit is not essential.

Users should be able to turn off time limits, adjust the time limit to a new preference before beginning, or easily extend the time limit when it is about to expire.

In most cases with digital publications, time limits are not essential to the content. They are more prevalent on the web, where they are used, for example, to end user sessions for security reasons or prevent users from blocking access to products for sale. The rare exception may occur in educational works if a test requires specific timing.
