From the US Access Board:
The Information Technology Industry Council (ITI) maintains a free reporting tool known as the Voluntary Product Accessibility Template (VPAT) to help determine whether information and communication technology products and services satisfy accessibility requirements, including the Section 508 Standards. ITI recently released revised editions of the VPAT (2.3) based on the Board’s revised 508 Standards (VPAT 2.3 508), including the referenced Web Content Accessibility Guidelines (WCAG 2.0). It also offers VPATs for WCAG 2.1 (VPAT 2.3 WCAG), the European Union’s ICT requirements (VPAT 2.3 EU), and another based on all three (VPAT 2.3 INT).
