Secondary link with accessibility requirements
The European Standard EN 301 549 (PDF) (external link) illustrates the relationship between the accessibility criteria and the accessibility requirements of users. So-called functional performance statements can be assigned to the criteria. 11 functional performance statements are defined:
- Use without vision
- Use with limited vision
- Use without color perception
- Use without hearing
- Use with limited hearing
- Use without voice
- Use with limited handling or force
- Use with limited range
- Minimizes triggers for light-sensitive seizures
- Use with cognitive limitations
- Privacy
If an accessibility criterion partially supports a functional performance statement because some users may use the function in certain situations, then there is a secondary relationship.
