Particular cases - RGAA 3 2017

Images

Criterion 1.3

There is a particular case of management when the image is used as a CAPTCHA or as a test image. In this situation, where it is not possible to give a relevant alternative without compromizing the function or the CAPTCHA or test, the criterion is not applicable.

Note: the case of CAPTCHA and test images is handled specifically by the criterion 1.4.

Criterion 1.8

For this criterion, there is a particular case management when the text is part of a logo or a graphic element associated with the identity of an organization or a company (a slogan, for example). In these situations, the criterion is not applicable for these items.

Note 1: Changes of color when taking focus are not affected by the application of the test, unless the content also changes when taking focus.

Note 2: the indications of link state (active or visited) are not affected by the application of the criterion.

Criterion 1.9

For this criterion, there is a particular case management when the text is part of a logo or a graphic element associated with the identity of an organization or a company (a slogan, for example). In these situations, the criterion is not applicable for these items.

Note 1: Changes of color when taking focus are not affected by the application of the test, unless the content also changes when taking focus.

Note 2: the indications of link state (active or visited) are not affected by the application of the criterion.

Colors

Criteria 3.3 - 3.4

For these criteria, there is a particular case management when the text is part of a logo or a graphic element associated with the identity of an organization or a company. In these situations, the criteria are not applicable for these items.

Note 1: The particular case concerning the texts associated with the graphic identity of an organization or a company should be limited to specific elements such as a slogan. In case it is an entire graphic identity, especially when the graphic identity is imposed, that is problematic, like a choice of font color for example, the solution is to resort to an alternative version, with sufficiently high contrast.

Note 2: Changes of color when taking focus are not affected by the application of the test, unless the content also changes when taking focus.

Note 3: the indications of link state (active or visited) are not affected by the application of the criterion.

For these criteria, there is a particular case of management when the image of text is used as a CAPTCHA or as a test image. In this situation, the criteria are not applicable.

There is a particular case management when:

• the time-based media is used for decorative purposes (ie it contains no information);
• the time-based media is itself an alternative to a content in the page (a sign language video or a spoken version of a text, for example);
• the time-based media is used to access a larger version;
• the time-based media is used as a CAPTCHA;

In these situations, the criterion is not applicable.

Criterion 4.19

Criterion 7.5

There is a particular case management when the unsolicited warning relates to an emergency, event, or a sudden and unexpected situation that requires immediate action to preserve health, safety or property. In these situations, the criterion is not applicable.

Mandatory elements

Criterion 8.2

There is a particular case management regarding the compliance of HTML code:

To accompany the gradual support of HTML5 by browsers, accessibility APIs and assistive technologies, some criteria may require the presence of attributes or tags declared "obsolete" in HTML5. In this case the test is not applicable 8.2.2.

Criterion 8.7

There is a particular case management regarding the language change in the following cases:

• proper name: the criterion is not applicable;
• common name in a foreign language, present in the official dictionary of the default human language of the web page, the criterion is not applicable (Note: the official dictionary is recommended by the academy in charge of the language in question).

For any request to the service of the dictionary of the French Academy, use the online French academy contact form;
• the term in foreign language was previously submitted by the user via a form field and displayed on the page (such as the reminder of the search term, in the case of a search engine), the criterion is not applicable;
• text in a language that can not be determined: the criterion is not applicable.

Note: For common names in a foreign language, absent in the official dictionary of the default human language of the website, and adopted in the common language (eg: rendezvous): the criterion is applicable only when the absence of language specification may cause misunderstanding during restitution.

However, an automatic redirection that leads to the new version of a page from an outdated url is essential; the criterion is not applicable.

Criterion 13.6

There is a particular case management when the document is generated dynamically (eg an invoice). In this situation, the weight indication is optional, other indications (file type and language) are still required.
