Section 508 and PDFs in the United States

The Revised 508 Standards cover federal ICT. E205 addresses electronic content, including public-facing material and specified categories of internal official communications. Documents can therefore be relevant even when they are not publicly available online.

Federal refers to the US federal government, as distinct from state governments, local bodies and private businesses. Section 508 concerns agencies developing, procuring, maintaining and using ICT. A supplier may encounter the requirements through a federal contract; that does not mean every US business has identical document obligations.

E205.2 addresses public-facing electronic content. E205.3 covers specified official communications that are not public: emergency notices, administrative decisions, policy and programme announcements, benefits or employment notices, formal acknowledgements, questionnaires, templates, forms and educational or training materials. The list also includes intranet content designed as web pages.

An employee training manual can therefore be relevant without ever appearing on a public website. Start with its use and the procuring agency’s requirements, rather than whether a search engine can find it.

E205.4 references WCAG 2.0 A and AA. For non-web documents, it excepts criteria 2.4.1, 2.4.5, 3.2.3 and 3.2.4. Do not automatically substitute WCAG 2.2 as the statutory requirement in that reference.

The four exceptions concern bypassing repeated blocks, multiple ways of locating content, consistent navigation and consistent identification within those criteria’s scope. They do not remove other requirements for image alternatives, headings, meaningful sequence or keyboard operation of document functions.

E205.4.1 also specifies substitutions such as reading “web page” as “document” when applying criteria to non-web documents. Review the document as a whole instead of uncritically reusing a website checklist.

A supplier provides only a PDF/UA report. The customer needs to ask how the delivery requirements were assessed, including aspects the report does not test. PDF/UA can provide technical support but does not fully replace assessment against E205.4.

• Documents and user tasks included in the scope.
• Applicable parts of the Revised 508 Standards.
• Manual and automated assessment methods.
• How issues, limitations and file versions will be reported.

Suppose the contract covers a training manual with exercises and a separate PDF form. Ask the buyer to confirm the applicable 508 provisions and any additional contractual requirements. Define tasks for each document: find a lesson, understand an illustrated instruction, read a table and complete the form.

A result row can identify the criterion, the assessed location or function, the method and an explanation. For a form field, “keyboard: pass” is inadequate without addressing focus sequence and how field names are presented.

Maintain that precision at delivery. The report should cover the actual supplied files. If templates are included, explain how to create further documents without breaking their structure. A good sample is useful but does not prove every future export from the template will be correct.
