WCAG 2.0 joins PDF/UA as an ISO standard


With Monday’s publication of W3C’s Web Content Accessibility Guidelines (WCAG 2.0) as ISO/IEC 40500, ISO standards now provide accessibility requirements for a large fraction of the world’s electronic content.

While ISO 14289 (PDF/UA) governs the creation and use of accessible PDF documents and forms, ISO/IEC 40500 (WCAG 2.0) provides normative principles, guidelines and success criteria for accessible web content. WCAG 2.0 is fundamentally rooted in traditional web technologies such as HTML, CSS and JavaScript, but the standard also provides much-needed guidance for multimedia, graphic design and other considerations.

Organizations that implement both WCAG 2.0 and PDF/UA will be able to meet the highest standards for ensuring both web-based and PDF content is accessible to users with disabilities.

Chairman of the PDF Association Olaf Drümmer said: “The PDF Association welcomes the addition of WCAG 2.0 to the expanding list of ISO standards addressing accessibility in electronic content.  Coupled with PDF/UA, which was published in August of 2012, it’s now possible to use ISO standards to meet the needs of organizations for a standardized approach to accessibility across a wide range of content.”
