WCAG 2.0 is now also ISO/IEC 40500
Web Content Accessibility Guidelines 2.0 (WCAG 2.0) is now also an ISO International Standard: ISO/IEC 40500:2012. ISO/IEC 40500 is exactly the same as the original WCAG 2.0 standard from the W3C's Web Accessibility Initiative (WAI). WCAG 2.0 was first released in 2008 and is now adopted and referred to by many organizations and governments. The fact that it is now an ISO standard means that the countries that use the ISO technical standards may adopt WCAG 2.0 by referring to ISO/IEC 40500.
If you are already working with WCAG 2.0, you can now say that you also work with an ISO standard, namely ISO/IEC 40500 standard.
What is WCAG 2.0 and who is it for?
WCAG 2.0 explains how web content should be accessible to persons with disabilities. These guidelines will help the internet that is more accessible to users with disabilities and will benefit all users. WCAG 2.0 is developed by W3C in collaboration with individuals and organizations throughout the world. The goal is to get a standard for web content that meets the needs of individuals, organizations and governments internationally. WCAG 2.0 is primarily designed for web developers, web authors and web designers etc. In other words, WCAG 2.0 is a technical standard and not an introduction to availability. WCAG 2.0 is a stable technical standard with 12 guidelines which are organized under 4 principles: perceivable, operable, understandable, and robust. For each of these four guidelines, there are testable success criteria at three levels: A, AA and AAA.
Universal design in Norway
The Web is becoming an important tool for everyday tasks. The ISO/IEC 40500:2012 standard will increase accessibility for people with disabilities. W3C's Web Accessibility Initiative (WAI) is an effort to make web pages disability-friendly. Universal design should enable websites so everyone can participate. In Norway, the universal design of ICT solutions is a legal requirement for both the public and private sectors (§ 14 in the Anti-Discrimination and Accessibility Act). All new ICT solutions should be universally designed. This means that new websites aimed at the public must built on recognized international standards (ISO/IEC 40500) and they must meet at least 35 of 61 of the success criteria in WCAG 2.0.
WAI is a win-win strategy
Not only users with disabilities take benefits of WAI, WCAG 2.0 and ISO/IEC 40500. In fact, WCAG 2.0 requires compatibility with both current user agents and future user agents. Add that even WCAG 1.0 contributes to better universal design. Examples of this are increased user-friendliness of websites using multi-modality, different learning styles using redundant text/audio/video, more efficient site maintenance with CSS, and faster searching and indexing of content with captioning of audio files support. Therefore, WCAG 2.0 provides user-friendly solutions both now and in the future. It will make the web more usable for all. The conclusion is clear: This benefits all users.
