Testing for §1194.22 (m): Applets & Plug-ins

Back Next


Applets and plug-ins are self-contained software applications that can be downloaded or installed to allow the display of special, often proprietary, content on a web page. This module will focus on how to test applets and plug-ins for accessibility under Section 508 §1194.22.

The section 508 requirement covering this is: §1194.22 (m) When a web page requires that an applet, plug-in or other application be present on the client system to interpret page content, the page must provide a link to a plug-in or applet that complies with §1194.21 (a) through (l).

This requirement has two parts:

  • Web pages that require applets and plug-ins must provide a link to them.
  • The applets and plug-ins themselves must comply with Section 508 §1194.21, Software Applications and Operating Systems.

VA-tested applets and plug-ins are listed on the VA website: http://www.va.gov/viewer.htm. Please note that if you link directly to an application provider's download site from a VA site, be careful not to promote their product using their free banners.

Testing for Section 508 §1194.21 requirements for other applets and plug-ins is covered in a separate course, Testing Software Applications and Operating Systems for 508 Compliance. These requirements apply to both the viewers (e.g., the Flash Player or Acrobat Reader) and the content you create to view in them (e.g., .swf and .pdf files).
