Summary of Section 508 Standards Compliance
ACEs products and services comply with Section 508 of the Rehabilitation Action of 1973 as summarized below.
General (Subpart A)
The standards define the types of technology covered and set forth
provisions that establish a minimum level of accessibility. The
application section (1194.2) outlines the scope and coverage of the
standards. The standards cover the full range of electronic and
information technologies in the Federal sector, including those used for
communication, duplication, computing, storage, presentation, control,
transport and production. This includes computers, software, networks,
peripherals and other types of electronic office equipment. The standards
define electronic and information technology, in part, as "any
equipment or interconnected system or subsystem of equipment, that is used
in the creation, conversion, or duplication of data or information."
Subpart A also explains what is exempt (1194.3), defines terms
(1194.4), and generally recognizes alternatives to what is required that
provide equal or greater access (1194.5). Consistent with the law, the
standards exempt systems used for military command, weaponry,
intelligence, and cryptologic activities (but not routine business and
administrative systems used for other defense-related purposes or by
defense agencies or personnel). The standards also exempt "back office"
equipment used only by service personnel for maintenance, repair, or
similar purposes.
The standards cover technology procured by Federal agencies under
contract with a private entity, but apply only to those products directly
relevant to the contract and its deliverables. An exception clarifies that
the standards do not apply to technology that is incidental to a Federal
contract. Thus, those products that are not specified as part of a
contract with a Federal agency would not have to comply with the
standards. For example, a firm that produces a report for a Federal agency
under a contract would not have to procure accessible computers and word
processing software even if they were used exclusively for the contract;
however, compliance would be required if such products were to become the
property of the Federal agency as contract deliverables or if the Federal
agency purchased the products to be used by the contractor as part of the
project. If a Federal agency contracts with a firm to develop its web
site, the standards would apply to the new web site for the agency but not
to the firm's own web site.
Technical Standards (Subpart B)
The standards provide criteria specific to various types of
technologies, including:
- software applications and operating systems
- web-based information or applications
- telecommunication products
- video and multimedia products
- self contained, closed products (e.g., information kiosks,
calculators, and fax machines)
- desktop and portable computers
This section provides technical specifications and performance-based
requirements, which focus on the functional capabilities of covered
technologies. This dual approach recognizes the dynamic and continually
evolving nature of the technology involved as well as the need for clear
and specific standards to facilitate compliance. Certain provisions are
designed to ensure compatibility with adaptive equipment people with
disabilities commonly use for information and communication access, such
as screen readers, Braille displays, and TTYs.
Software Applications and Operating Systems
(1194.21)
Most of the specifications for software pertain to usability for
people with vision impairments. For example, one provision requires
alternative keyboard navigation, which is essential for people with
vision impairments who cannot rely on pointing devices, such as a mouse.
Other provisions address animated displays, color and contrast settings,
flash rate, and electronic forms, among others.
Web-based Intranet and Internet Information and
Applications (1194.22)
The criteria for web-based technology and information are based on
access guidelines developed by the Web Accessibility Initiative of the
World Wide Web Consortium. Many of these provisions ensure access for
people with vision impairments who rely on various assistive products to
access computer-based information, such as screen readers, which
translate what's on a computer screen into automated audible output, and
refreshable Braille displays. Certain conventions, such as verbal tags
or identification of graphics and format devices, like frames, are
necessary so that these devices can "read" them for the user in a
sensible way. The standards do not prohibit the use of web site graphics
or animation. Instead, the standards aim to ensure that such information
is also available in an accessible format. Generally, this means use of
text labels or descriptors for graphics and certain format elements.
(HTML code already provides an "Alt Text" tag for graphics which can
serve as a verbal descriptor for graphics). This section also addresses
the usability of multimedia presentations, image maps, style sheets,
scripting languages, applets and plug-ins, and electronic forms.
The standards apply to Federal web sites but not to private sector
web sites (unless a site is provided under contract to a Federal agency,
in which case only that web site or portion covered by the contract
would have to comply). Accessible sites offer significant advantages
that go beyond access. For example, those with "text-only" options
provide a faster downloading alternative and can facilitate transmission
of web-based data to cell phones and personal digital assistants.
Telecommunications Products (1194.23)
The criteria of this section are designed primarily to ensure access
to people who are deaf or hard of hearing. This includes compatibility
with hearing aids, cochlear implants, assistive listening devices, and
TTYs. TTYs are devices that enable people with hearing or speech
impairments to communicate over the telephone; they typically include an
acoustic coupler for the telephone handset, a simplified keyboard, and a
visible message display. One requirement calls for a standard
non-acoustic TTY connection point for telecommunication products that
allow voice communication but that do provide TTY functionality. Other
specifications address adjustable volume controls for output, product
interface with hearing technologies, and the usability of keys and
controls by people who may have impaired vision or limited dexterity or
motor control.
Video or Multimedia Products (1194.24)
Multimedia products involve more than one media and include, but are
not limited to, video programs, narrated slide production, and computer
generated presentations. Provisions address caption decoder circuitry
(for any system with a screen larger than 13 inches) and secondary audio
channels for television tuners, including tuner cards for use in
computers. The standards also require captioning and audio description
for certain training and informational multimedia productions developed
or procured by Federal agencies. The standards also provide that viewers
be able to turn captioning or video description features on or off.
Self Contained, Closed Products (1194.25)
This section covers products that generally have imbedded software
but are often designed in such a way that a user cannot easily attach or
install assistive technology. Examples include information kiosks,
information transaction machines, copiers, printers, calculators, fax
machines, and similar types of products. The standards require that
access features be built into the system so users do not have to attach
an assistive device to it. Other specifications address mechanisms for
private listening (handset or a standard headphone jack), touchscreens,
auditory output and adjustable volume controls, and location of controls
in accessible reach ranges.
Desktop and Portable Computers (1194.26)
This section focuses on keyboards and other mechanically operated
controls, touch screens, use of biometric form of identification, and
ports and connectors.
Functional Performance Criteria (Subpart
C)
The performance requirements of this section are intended for overall
product evaluation and for technologies or components for which there is
no specific requirement under the technical standards in Subpart B. These
criteria are designed to ensure that the individual accessible components
work together to create an accessible product. They cover operation,
including input and control functions, operation of mechanical mechanisms,
and access to visual and audible information. These provisions are
structured to allow people with sensory or physical disabilities to
locate, identify, and operate input, control and mechanical functions and
to access the information provided, including text, static or dynamic
images, icons, labels, sounds or incidental operating cues. For example,
one provision requires that at least one mode allow operation by people
with low vision (visual acuity between 20/70 and 20/200) without relying
on audio input since many people with low vision may also have a hearing
loss.
Information, Documentation, and Support (Subpart
D)
The standards also address access to all information, documentation,
and support provided to end users (e.g., Federal employees) of covered
technologies. This includes user guides, installation guides for end-user
installable devices, and customer support and technical support
communications. Such information must be available in alternate formats
upon request at no additional charge. Alternate formats or methods of
communication, can include Braille, cassette recordings, large print,
electronic text, Internet postings, TTY access, and captioning and audio
description for video materials.
