Open "Screen reader preview", the contents of the file are displayed as they will be rendered, with the element(s) used preceding each content.
Locate the images conveying information in the original document.
Check in PAC that the alternatives (ALT element or content linked by an adjacent link) contain all the information needed to understand the content with which the image is associated.
In these situations, the criterion does not apply:

The presentation of the text is considered essential to the information conveyed by the image, for example an image used to illustrate the graphic aspect of a font.
Assessment methodology
With PAC
Open the PDF file.
Open "Screen reader preview", the contents of the file are displayed as they will be rendered, with the element(s) used preceding each content.
Locate all text that may be presented as an image in the original document.
Check in PAC that each text is actually presented in image form (FIGURE element).
Check that the image is accompanied by an anchor (LINK element) enabling an alternative text version to be consulted.

Test 2.1.1For each word or set of words whose colouring carries information, the information must not be provided by colour only. Is this rule respected?Test 2.1.1
Test 2.1.2For each indication of colour given by text, the information must not be provided by colour only. Is this rule respected?Test 2.1.2
Test 2.1.3For each image conveying information, the information must not be provided by colour only. Is this rule respected?Test 2.1.3

This topic only covers interactive forms filled in with Acrobat Reader.
PDF forms can only be created using Adobe Acrobat Pro, Adobe InDesign or specialised PDF form editing software.
In addition to the assessments proposed in this section, testing by a person with disabilities using their own assistive technology is recommended to check:
that the PDF form is perfectly usable,
that all the input fields can be filled in,
and that the user has all the necessary information.
PDF/UA-2: 8.10.2.2 Labels, 8.10.2.3 Contents entry, 8.10.3.2.3 Check boxes and radio buttons, 8.10.3.4 Choice fields.
Criterion 10.3Is every label associated with a form field having the same function and repeated several times in the same document consistent?Criterion 10.3Compliance level AA
Criterion 10.5Are the mandatory or optional form fields correctly identified (excluding special cases)?Criterion 10.5Compliance level A
Tests
Test 10.5.1Does each mandatory or optional form field meet these conditions?
Test 10.5.1
The required or optional nature is visible and explicit.
The required or optional nature is accessible to assistive technologies.
Notes and special cases
Special cases
When the form contains only one field, the criterion is not applicable.
If all fields in a form are mandatory, the criterion remains applicable.
Technical notes
Test 10.5.1 addresses fields independently; however, it must be ensured that the method chosen to alert users (mandatory fields or optional fields) is consistent throughout the form.
Assessment methodology
With Acrobat Reader
Open the PDF file.
Use the tab key to exit fields or, if the form allows, submit the form.
Identify fields marked as mandatory in the document.
Check that the mandatory or optional status is clearly indicated:
either by text (e.g. ‘mandatory’);
or by a visual indication (e.g. "*") defined before the form by a text indication (e.g. ‘Fields preceded by ("*") are mandatory’).
Check that the indication of whether a field is mandatory or optional is:
visible in the document, prior to form validation;
contained in the tooltip, prior to form validation.

Notes and special cases
Special cases
The criterion is not applicable when the error message is generated automatically by the PDF editing software.
Assessment methodology
With Acrobat Reader
Open the PDF file.
Fill in form fields with values that are likely to cause input errors (e.g. entering an incorrectly formatted email address).
Use the tab key to exit fields or, if the form allows it, to send the form.
For each error message relating to a data type, format or expected value displayed in an information window, check that the error message includes an example of an actual input (for an email address, check that it includes a real address in the format ‘jean.dupont@sample.com’).
For each error message relating to a data type, format or expected value specified directly in the document, check
that it contains an example of a real input (for an email address, check that a real address is mentioned, such as ‘jean.dupont@sample.com’);
that it is visible near the field;
that the tooltip contains information similar to the visible text.

Test 10.11.1For each form which modifies or deletes data, or which transmits answers to a test or examination, or whose validation has financial or legal consequences, can the data entered be modified, updated or recovered by the user?Test 10.11.1
Assessment methodology

Fill in the form.
For all data of a financial (e.g. an income statement), legal (e.g. an administrative act reference) or personal (e.g. a telephone number) nature, for each form that transmits answers to a test or examination, check that the user can:
modify or cancel data and carried out actions on this data while it is being entered (for example, a field is not deactivated after a value has been entered);
explicitly confirm the sending of this data using a dedicated mechanism (e.g. by ticking a confirmation box).
For each mechanism (e.g. a button) used to modify or delete data entered, check that the user can
cancel the changes made;
recover deleted data;
or explicitly confirm the modification or deletion of this data using a dedicated mechanism (e.g. a checkbox).
