508 Chapter 1: Application and Administration
E101 General
E101.1 Purpose.These Revised 508 Standards, which consist of 508 Chapters 1 and 2 (Appendix A), along with Chapters 3 through 7 (Appendix C), contain scoping and technical requirements for information and communication technology (ICT) to ensure accessibility and usability by individuals with disabilities. Compliance with these standards is mandatory for Federal agencies subject to Section 508 of the Rehabilitation Act of 1973, as amended (29 U.S.C. 794d).
E101.2 Equivalent Facilitation. The use of an alternative design or technology that results in substantially equivalent or greater accessibility and usability by individuals with disabilities than would be provided by conformance to one or more of the requirements in Chapters 4 and 5 of the Revised 508 Standards is permitted. The functional performance criteria in Chapter 3 shall be used to determine whether substantially equivalent or greater accessibility and usability is provided to individuals with disabilities.
E101.3 Conventional Industry Tolerances. Dimensions are subject to conventional industry tolerances except where dimensions are stated as a range with specific minimum or maximum end points.
E101.4 Units of Measurement. Measurements are stated in metric and U.S. customary units. The values stated in each system (metric and U.S. customary units) may not be exact equivalents, and each system shall be used independently of the other.
E102 Referenced Standards
E102.1 Application. The specific editions of the standards listed in Chapter 7 are incorporated by reference into 508 Chapter 2 (Scoping Requirements) and Chapters 3 through 6 to the prescribed extent of each such reference. Where conflicts occur between the Revised 508 Standards and the referenced standards, these Revised 508 Standards apply.
