Assessment Procedures

The assessment procedure for determining whether your application conforms to this provision is simple. Utilize the following steps to perform your test:

  • Open the application to be tested.
  • Navigate through the application.
  • Search for flashing or blinking text, objects, or other elements.
  • Use an electronic tester to determine if the item has a flash or blink frequency greater than 2 Hz and lower than 55 Hz.
  • Make note of those animations that have a Hertz range of greater than 2 Hz and lower than 55 Hz. These are the items that will need to be addressed during remediation. Flashing or blinking objects need to be omitted from an application if they cannot be tested.
  • There may be tools to automate this procedure. Since all twelve provisions can not be measured in an automated way, manual test procedures must accompany any automated processes used to ensure complete testing is performed, and eliminate inaccurate results.

What actions can be taken to develop flashing text and objects that conform to this provision? What can be done if existing text and objects do not conform?
