Latest changes to accessibility standard

Find out about the latest changes to accessibility standard EN 301 549 and the rationale behind them.

Introduction

Standards can take a long time to be developed, as they require agreement from many different parties. As far as the WAD is concerned, only once a modified standard is harmonised through a reference in the Official Journal, does it have legal significance. So new versions of the WCAG or of EN 301 549 do not automatically change the legal obligations of the Member States with respect to the WAD.

In order for changes to have an effect on the WAD, first, the standard has to be updated, and then it needs to be referenced in the Official Journal.  The last change happened in August 2021. In this case EN 301 549 v2.1.2, which was referenced in the Official Journal in 2018, was replaced by v3.2.1. An overlap of several months until February 2022 was provided for in the legislation.

Reference lists on this page:

Changes in v3.2.1

The following table lists the changes between v2.1.2 and v3.2.1 of EN 301 549. Both versions build heavily on WCAG 2.1. Since WCAG 2.1 has not changed in this period, the changes in the new version are quite small. One important change in v3.2.1, due to an editorial oversight in v2.1.2, is that WCAG 2.1 now applies to documents downloaded from the web.

Clauses added in v3.2.1

Note that the row number in the first column refers to the row in Table A.1 of Annex of EN 301 549, v3.2.1.

Row Requirement Rationale
20 6.5.4 Synchronization between audio and video Was upgraded from a recommendation to a requirement in version 3.2.1
21 6.5.5 Visual indicator of audio with video A new requirement in version 3.2.1
22 6.5.6 Speaker identification with video (sign language) communication A new requirement in version 3.2.1
26 7.1.4 Captions characteristics A new requirement in version 3.2.1
27 7.1.5 Spoken subtitles A new requirement in version 3.2.1
81 9.6 WCAG conformance requirements This was in version 2.1.2 (as 9.5) but wrongly omitted from Table A.1
82 to 126 Downloadable document requirements (all based on WCAG 2.0 Newly added to Table A.1 in version 3.2.1 for the reason described above in 2.

Clauses removed in v3.2.1

This tables lists the requirements of EN 301 549 that go beyond WCAG 2.1, based on Table A.1 (covering websites) of Annex A in EN 301 549 v3.2.1. 

To note: Table A.2 (covering mobile applications) is not covered by WCAG at all, even though it makes use of requirements from WCAG. This is because the WCAG does not actually apply to mobile applications.

Requirements in EN 301 549 but not relevant to the WAD

Below are listed the requirements of EN 301 549 that are not listed in Table A.1 (covering websites) or Table A.2 (covering mobile applications) of Annex A in EN 301 549 v3.2.1.  They are therefore a part of the standard, but are not a part of the presumption of conformity to the WAD. 

Requirements not relevant because the WAD does not apply to hardware:

  • 5.1 Closed functionality
  • 6.5.2 Resolution item b)
  • 6.5.3 Frame rate item b)
  • 6.6 Alternatives to video-based services
  • 8 Hardware (in its entirety)

Requirements not relevant because the WAD does not apply to live time-based media:

  • 9.1.2.4 Captions (live)
  • 10.1.2.4 Captions (live)
  • 11.1.2.4 Captions (live)
