Accessibility Declaration

TU Wien makes every effort to make our website accessible in accordance with the Web Accessibility Act ("Web-Zugänglichkeits-Gesetz" - WZG).

This declaration on accessibility applies to websites of TU Wien, which are hosted on a CIT server and are connected to the central TU Wien TYPO3 system.

Efforts to support accessibility

TU Wien takes the following measures to ensure accessibility:

Accessibility is part of our internal guidelines.
Continuous training on accessibility is offered for our employees.
Formal methods for quality assurance of accessibility exist within the company.
We include people who rely on accessible websites in the development of our website.

Compliance status

This website is partially compliant with conformance level AA of the “Web Content Accessibility Guidelines – WCAG 2.2” or with the applicable European standard EN 301 549 V3.2.1 (2021-03) according to Directive (EU) 2016/2102 of the European Parliament and of the Council. It has been awarded the WACA quality seal in silver.

Known accessibility issues

Unfortunately, we still cannot completely exclude one or the other barrier. Please contact us if you notice a problem.

We are aware of the following recommendations for further improvement of our website:

Perceivable

Time-based media: Time-based media is not accessible in all cases because sufficient audio-descriptive alternatives may not be provided.
On the "Events" page, the contrast of the gray values is sufficient and WCAG-compliant, but especially on mobile, the information about time and place is written very small and gray and thus not optimally readable.
In the document overview, the links to the documents are only distinguished from the body text by color.

Operable

Not best practice: on the "Events" page in mobile view, the calendar is visually in front, but after the events in tab order.
When searching for events multiple times with the help of a screen reader, the focus is no longer placed at the top of the page.

Documents

Unfortunately, not all documents on our website are accessible yet.

Enforcement Procedure

The contact form of the complaints office can be found at www.ffg.at/form/kontaktformular-beschwerdestelle, opens an external URL in a new window.

These complaints are examined by the FFG to determine whether they relate to violations of the Web Accessibility Act (WZG), in particular deficiencies in compliance with accessibility requirements, by the federal government or an institution assigned to it.

If the complaint is justified, the FFG must make recommendations to the federal government or the legal entities concerned and propose measures to remedy the existing deficiencies.
