"With responsiveness and flexibility that meets unique needs and a thorough process that examines both products and the management systems that support them, UL’s experience and expertise in functional safety (FS) ensures accuracy and assurance, insight, and integrity."
The above paragraph is the summation of a 12-page Functional Safety brochure that I wrote for Underwriters Laboratories. As part of the broad scope of product safety, functional safety zeroes in on the safety-related systems of a product. The UL FS brochure provides an in-depth explainable of FS and how UL helps its client to achieve their FS goals.
