Voluntary Product Accessibility Template (VPAT) ® for Tenon

The purpose of the Voluntary Product Accessibility Template, or VPAT™, is to assist Federal contracting officials and other buyers in making preliminary assessments regarding the availability of commercial "Electronic and Information Technology" products and services with features that support accessibility. It is assumed and recommended 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.

Section 1194.21 Software Applications and Operating

Criteria Supporting Features Remarks and explanations
(a) When software is designed to run on a system that has a keyboard, product functions shall be executable from a keyboard where the function itself or the result of performing a function can be discerned textually. Supports with exceptions All core functionality is keyboard accessible. Tenon's dashboard contains charts that provide tooltips on hover. Those tooltips are not available via keyboard.
(b) Applications shall not disrupt or disable activated features of other products that are identified as accessibility features, where those features are developed and documented according to industry standards. Applications also shall not disrupt or disable activated features of any operating system that are identified as accessibility features where the application programming interface for those accessibility features has been documented by the manufacturer of the operating system and is available to the product developer. Supports Tenon does not disrupt or disable any accessibility features or assistive technologies, either built-in or external.
(c) A well-defined on-screen indication of the current focus shall be provided that moves among interactive interface elements as the input focus changes. The focus shall be programmatically exposed so that assistive technology can track focus and focus changes. Supports with exceptions All items that get focus are given a clear on-screen indication, with one exception. The "My Account Menu" on the top right of the screen when logged in does not provide any clear, visual indication of focus. All items that get focus are indicated as having focus in a programmatic way.
(d) Sufficient information about a user interface element including the identity, operation and state of the element shall be available to assistive technology. When an image represents a program element, the information conveyed by the image must also be available in text. Supports with exceptions All controls and interface elements expose proper name, state, role, and value information programmatically, with one exception. The State/ Province field shown to visitors outside the US on the checkout screen does not have a label.
(e) When bitmap images are used to identify controls, status indicators, or other programmatic elements, the meaning assigned to those images shall be consistent throughout an application's performance. Supports Tenon does not use bitmap images. Tenon's non-text objects are presented in SVG. All of the SVG objects have sufficient text alternatives which are consistent in their use.
(f) Textual information shall be provided through operating system functions for displaying text. The minimum information that shall be made available is text content, text input caret location, and text attributes. Supports All textual information is provided in the HTML source and therefore available via the operating system functions for displaying text.
(g) Applications shall not override user selected contrast and color selections and other individual display attributes. Supports Tenon does not override or interfere with user-selected contrast and color settings. Tenon uses responsive design. Tenon uses SVG icons, which honor Windows High Contrast Mode.
(h) When animation is displayed, the information shall be displayable in at least one non-animated presentation mode at the option of the user. Not applicable Tenon does not provide any content via animation
(i) Color coding shall not be used as the only means of conveying information, indicating an action, prompting a response, or distinguishing a visual element. Supports Tenon does not use color as the only means of conveying information, indicating an action, prompting a response, or distinguishing a visual element. Any information presented through the use of color is also conveyed in text or other programmatically distinguishable method.
(j) When a product permits a user to adjust color and contrast settings, a variety of color selections capable of producing a range of contrast levels shall be provided. Not applicable Tenon does not contain any mechanism for adjusting color or contrast.
(k) Software shall not use flashing or blinking text, objects, or other elements having a flash or blink frequency greater than 2 Hz and lower than 55 Hz. Not applicable Tenon does not contain any content that flashes or blinks
(l) When electronic forms are used, the form shall allow people using assistive technology to access the information, field elements, and functionality required for completion and submission of the form, including all directions and cues. Supports with exceptions. The State/ Province field shown to visitors outside the US on the checkout screen does not have a label. All other form fields are labelled properly and clearly. Tenon's error handling approach identifies each error, discloses the nature of the error, and provides field-level error messages that are programmatically associated with the control that has the error

Criteria Supporting Features Remarks and explanations
(a) A text equivalent for every non-text element shall be provided (e.g., via "alt", "longdesc", or in element content). Supports
(b) Equivalent alternatives for any multimedia presentation shall be synchronized with the presentation. Not applicable Tenon does not contain any multimedia presentations
(c) Web pages shall be designed so that all information conveyed with color is also available without color, for example from context or markup. Supports Tenon does not use color as the only means of conveying information, indicating an action, prompting a response, or distinguishing a visual element. Any information presented through the use of color is also conveyed in text or other programmatically distinguishable method.
(d) Documents shall be organized so they are readable without requiring an associated style sheet. Supports Stylesheets are not required in order to use Tenon.
(e) Redundant text links shall be provided for each active region of a server-side image map. Not applicable Tenon does not use image maps of any kind.
(f) Client-side image maps shall be provided instead of server-side image maps except where the regions cannot be defined with an available geometric shape. Not applicable Tenon does not use image maps of any kind.
(g) Row and column headers shall be identified for data tables. Supports All relevant table headers are identified via the TH element
(h) Markup shall be used to associate data cells and header cells for data tables that have two or more logical levels of row or column headers. Supports None of Tenon's data tables two or more logical levels of row or column headers. Tenon's tables are very simple in structure. All TH elements on Tenon's tables use scope attributes.
(i) Frames shall be titled with text that facilitates frame identification and navigation. Not applicable Tenon does not use frames.
(j) Pages shall be designed to avoid causing the screen to flicker with a frequency greater than 2 Hz and lower than 55 Hz. Supports No content on Tenon causes flicker
(k) A text-only page, with equivalent information or functionality, shall be provided to make a web site comply with the provisions of this part, when compliance cannot be accomplished in any other way. The content of the text-only page shall be updated whenever the primary page changes. Not applicable Alternate text-only pages are not necessary with Tenon.
(l) When pages utilize scripting languages to display content, or to create interface elements, the information provided by the script shall be identified with functional text that can be read by assistive technology. Not supported Substantial portions of Tenon require JavaScript to function properly. This 508 provision was written in a time before assistive technologies could effectively handle client-side scripting. Modern assistive technologies handle JavaScript well. Tenon's usage of JavaScript is accessible and performs well for users of modern assistive technologies and modern browsers.
(m) When a web page requires that an applet, plug-in or other application be present on the client system to interpret page content, the page must provide a link to a plug-in or applet that complies with ยง1194.21(a) through (l). Not applicable No portion of Tenon requires anything beyond that which is provided in a modern web browser.
(n) When electronic forms are designed to be completed online, the form shall allow people using assistive technology to access the information, field elements, and functionality required for completion and submission of the form, including all directions and cues. Supports with exceptions The State/ Province field shown to visitors outside the US on the checkout screen does not have a label. All other form fields are labelled properly and clearly. Tenon's error handling approach identifies each error, discloses the nature of the error, and provides field-level error messages that are programmatically associated with the control that has the error
(o) A method shall be provided that permits users to skip repetitive navigation links. Supports Tenon uses ARIA landmarks to allow users to skip between sections of the page. Tenon also provides a "skip link" on all screens
(p) When a timed response is required, the user shall be alerted and given sufficient time to indicate more time is required. Supports with exceptions No functionality within Tenon requires a timed response. However, users' sessions will time out with no opportunity to extend. The length of time before a user will be "timed out" can be adjusted in their settings.
