Content accessible without time constraints
What this criterion checks
This criterion maps to 2.2.1 Timing Adjustable. A detailed plain-language description is maintained in the WebLens criteria catalogue; the WCAG sub-test breakdown below describes exactly what the agent checks and what it does not.
How it's assessed
WebLens walks each user journey, captures a screenshot at every step, and an agent reasons over that evidence. See the how WebLens works for the full pipeline and the deterministic checks layered in for accessibility.
Sub-test coverage
2.2.1 Timing Adjustable is broken into 6 sub-tests. Coverage is honest about where the agent is reliable, where it only partially checks the requirement, and where a human reviewer is still needed.
1 partial5 not covered
- Identification of time limitsPartial
Our tool detects one specific type of time limit: meta http-equiv="refresh" elements with a refresh interval under 20 hours. It does not detect other time limits such as session timeouts, JavaScript-based countdown timers, auto-advancing content, or timed form submissions.
- Adjust optionNot covered
Checking whether users can adjust time limits to at least 10x the default requires behavioral testing. Not automatable with static code analysis.
- At least one condition metNot covered
Verifying that each time limit satisfies at least one of the six conditions (turn off, adjust, extend, real-time exception, essential exception, or 20-hour exception) requires comprehensive behavioral and contextual review. Our tool only detects meta-refresh as one specific type of time limit.
- Exception verificationNot covered
If no user-controllable option (turn off, adjust, extend) is available, verifying whether a valid exception applies (real-time event, essential activity, or time limit over 20 hours) requires human judgment. Not automatable.
- Extend optionNot covered
Checking whether users receive a warning before time expiry with 20+ seconds to extend via a simple action requires behavioral testing. Not automatable.
- Turn off optionNot covered
Our tool flags the presence of meta-refresh but does not check whether users can turn off, adjust, or extend time limits. For meta-refresh specifically, the recommended fix is removal or increasing the interval beyond 20 hours.
How reliable it is
This criterion is still building up testing data, so confirm its findings as you review. See Accuracy & confidence for how the confidence tags are set.
