Statement of accessibility

The AENOR web portal has been developed by adopting a series of measures to improve accessibility, and ensure that it can be used by as many users as possible, regardless of their personal or technological limitations.

To this end, work has been carried out based on the requirements of Priority 1 and Priority 2 of the UNE 139803:2012 Accessibility Requirement for web content, corresponding to the AA (Double-A) compliance level of the international Accessibility for Web Content WCAG 2.0 guidelines defined by the World Wide Web Consortium (W3C).

Semi-automatic tools and a manual audit have been used to check compliance with the requirements applicable to this Double-A level, and work is currently underway to resolve some of the problems identified.

Advantages to website users provided by implementing accessibility techniques and criteria, include:

  • Facilitating access for users, regardless of their capabilities, environment, or technological infrastructure.
  • Facilitating access through various web browsers (viewed correctly in the latest versions of the most widely used web browsers, such as, Microsoft Internet Explorer (except obsolete version 6), Netscape, Mozilla Firefox, Safari and Google Chrome).
  • The content is well-structured and clear, facilitating its interpretation.
  • Improved navigation and user experience.

To do this the measures taken include:
  • Separation between content and presentation, using cascading style sheets (CSS).
  • Text alternatives are added to the non-text content.
  • Implementation of content hierarchy, using appropriate structural and semantic marking for information and relationships between content.
  • Application of the W3C standards.
  • Improved navigability, browser menu visible on all pages, breadcrumb navigation.
  • The size of the text is defined in relative units so that it can be expanded or reduced by the user. The text can be resized in such a way that it can be read by visually impaired users. Use CTRL+ or CTRL -
  • Breadcrumb navigation is included on every page; this shows the user the route they followed to get to that page from the main page.
  • Acronyms and abbreviations are explained.
  • All links are identified and offer details of the function or hyperlink destination. The formats of downloadable files are identified, such as PDFs.
  • The user is warned when a new pop-up window is going to open. 


Contents provided to give further information in formats other than HTML, such as PDF mostly, do not incorporate accessibility features. AENOR undertakes to provide these documents in an accessible format to whoever requests them.
