Voluntary
Product Accessibility Template
Version 1.1
8/3/01
The purpose of the Voluntary Product Accessibility Template is to
assist Federal contracting officials in making preliminary assessments
regarding the availability of commercial Electronic and Information
Technology products and services with features that support accessibility.
It is assumed that offerers will provide additional contact information
to facilitate more detailed inquiries.
The first table of the Template provides a summary view of the section
508 Standards. The subsequent tables provide more detailed views of
each subsection. There are three columns in each table. Column one
of the Summary Table describes the subsections of subparts B and C
of the Standards. The second column describes the supporting features
of the product or refers you to the corresponding detailed table,
"e.g., equivalent facilitation." The third column contains any additional
remarks and explanations regarding the product. In the subsequent
tables, the first column contains the lettered paragraphs of the subsections.
The second column describes the supporting features of the product
with regard to that paragraph. The third column contains any additional
remarks and explanations regarding the product.
