Evaluation of Detectable Warnings Advisory Committee
The Evaluation of Detectable Warnings Advisory Committee (EDWAC) proposes durability and degradation testing standards to ensure that detectable warnings remain effective, thereby improving safety.
Detectable warnings are a distinctive surface pattern of domes detectable by cane or foot that alert people with vision impairments of their approach to street crossings and hazardous drop-offs. The Evaluation of Detectable Warnings Advisory Committee (EDWAC) proposes durability and degradation testing standards to ensure that detectable warnings remain effective, thereby improving safety. To aid in this effort, DSA contracted with Underwriters Laboratories Inc. (UL) to provide technical expertise and facilitate the efforts of the committee. UL is an independent, not-for-profit organization that has evaluated products, materials, and systems in the interest of public safety for over 100 years. UL has developed more than 800 Standards for Safety, which are essential to promote public safety and confidence.
The committee will issue a final report of recommendations that will be used to develop the Standard Test Method for the Evaluation of Detectable Warning Products and Directional Surfaces.
