Meet Section 508 hardware accessibility requirements with tested evidence
Specialized accessibility testing for physical products, kiosks, terminals, and embedded interfaces — with documentation that passes federal procurement.
Trusted by teams across regulated and public-sector environments
Why hardware manufacturers can't ignore digital accessibility
Physical + Digital Interface Gap
Hardware products with embedded software need both physical accessibility assessment and digital interface testing — most vendors only do one.
Section 508 Hardware Requirements
Federal procurement mandates specific hardware accessibility criteria that go beyond software WCAG — including reach ranges, operable parts, and tactile feedback.
International Compliance Complexity
Selling globally means meeting EN 301 549 and the European Accessibility Act alongside the US Section 508 standards, and each names different criteria for the same physical product.
Which accessibility standards apply to hardware manufacturers
Standard
Applies
Section 508
Binds federal agencies and reaches you through procurement. Chapter 4 of the Revised 508 Standards sets the hardware requirements and 402 covers closed functionality.
EN 301 549
European ICT accessibility standard. Clause 8 covers hardware and Clause 11 covers non-web software such as an embedded interface.
ADA
Binds the organizations that deploy your devices: Title II for state and local government, Title III for public accommodations. Their reach range and operable parts obligations reach you as purchase requirements.
WCAG 2.2 AA
For embedded software interfaces and web-based management consoles. Section 508 incorporates WCAG 2.0 Level AA by reference, so the version you are held to is the one your contract names.
EAA
European Accessibility Act. Binds manufacturers placing covered products on the EU market, including self-service terminals, and has applied since June 28, 2025.
AODA
Ontario legislation, not a national one. It requires organizations in Ontario to account for accessibility when they procure self-service kiosks, so it reaches your product through the buyer rather than binding you as the manufacturer.
Accessibility barriers we frequently find
Touchscreen-Only Interfaces
Kiosks and terminals that require touch interaction without alternative input methods for users with motor disabilities.
Insufficient Color Contrast on Displays
Embedded displays with low contrast ratios, especially in varying lighting conditions.
Missing Tactile Indicators
Physical controls without tactile differentiation for users with visual impairments.
Audio-Only Feedback
Devices that rely solely on audio cues without visual or tactile alternatives for deaf or hard-of-hearing users.
Embedded Software Accessibility
On-device software interfaces lacking keyboard navigation, screen reader support, or proper focus management.
Reach Range & Operable Parts
Physical controls placed outside accessible reach ranges defined by Section 508 and ADA standards.
How we help hardware manufacturers
Hardware Accessibility Testing
Comprehensive testing of physical products against Section 508 hardware requirements and EN 301 549.
Hardware VPAT Documentation
One completed ACR, produced from the current VPAT template, covering hardware criteria alongside the embedded software interfaces so federal and enterprise buyers can accept it in review.
Embedded Interface Audit
WCAG testing for touchscreen interfaces, management consoles, and on-device software.
Design Consultation
Early-stage accessibility guidance for product teams designing hardware interfaces and physical controls.
Kiosk Manufacturer Achieves Federal Procurement Approval
Challenge
A self-service kiosk manufacturer was blocked from a major government contract because their VPAT didn't address Section 508 hardware-specific criteria.
Solution
ADACP conducted physical accessibility testing and an embedded software WCAG audit, then produced a single ACR from the VPAT template covering all applicable hardware and software criteria.
Outcome
The manufacturer passed federal procurement review and secured deployment across 200+ government facilities.

Accessibility checklist for hardware manufacturers
- Physical controls are operable with one hand and don't require tight grasping or twisting
- Controls are within accessible reach ranges (407 Operable Parts in the Revised 508 Standards)
- Touchscreen interfaces provide alternative input methods
- Visual displays meet minimum contrast ratios in typical operating conditions
- Audio output includes visual and/or tactile alternatives
- Tactile indicators differentiate controls for users with visual impairments
- Embedded software meets WCAG 2.2 AA success criteria
- Product documentation is available in accessible formats (602 Support Documentation)
- Physical dimensions accommodate wheelchair users
- Status indicators use more than color alone
- Connection points and ports are clearly labeled and accessible
- The ACR you hand a buyer, completed from the VPAT template, covers both hardware and embedded software criteria
Our process for hardware manufacturers
- 01
Product Assessment
We evaluate your hardware product, embedded interfaces, and management software to determine applicable accessibility standards and testing scope.
- 02
Physical & Digital Testing
Combined testing of physical accessibility (reach, operable parts, tactile) and embedded software interfaces (WCAG, keyboard, screen reader).
- 03
Comprehensive VPAT
The ACR, completed from the current VPAT template, covering hardware and software criteria with evidence mapped to each tested requirement.
- 04
Design Recommendations
Specific guidance for product engineering teams on addressing physical and digital accessibility gaps.
- 05
Verification & Updates
Re-testing after design changes, and an updated ACR so the conformance documentation still matches the product you ship.
Why choose ADACP for hardware manufacturers
Combined Hardware + Software Testing
Most accessibility firms only test software. We have the expertise and methodology to test physical products alongside embedded interfaces.
Section 508 Hardware Expertise
We work from Chapter 4 of the Revised 508 Standards, including 402 Closed Functionality, 407 Operable Parts and 409 Status Indicators, rather than from a software checklist with a hardware section bolted on.
International Standards Coverage
We test against EN 301 549, EAA, and other international hardware accessibility standards for global market access.
Product Design Consultation
We work with your engineering team during the design phase to prevent accessibility issues before manufacturing.

Who does this work
David LoPresti works directly with technology manufacturers and government contractors to evaluate accessibility conformance and prepare the documentation required during procurement and contract reviews. On a device engagement that means the product is evaluated against the hardware chapter of the Revised 508 Standards, including the closed functionality requirements that apply when a user cannot attach their own assistive technology, alongside the embedded and management interfaces, and you receive findings your engineers can act on plus an ACR completed from the current VPAT template that claims only what the testing supports.
