Underwriters Laboratories (UL) is doing a cannonball into the deep end of the “autonomous standards” pool.

By the end of this year, designers of self-driving vehicles, mining robots, unmanned aerial vehicles (UAVs), and a plethora of other industrial systems featuring autonomy could be adhering to an emerging UL Standard, dubbed UL 4600, that would cover autonomous product safety.

At least this is the goal set by the UL and the Edge Case Research (ECR) – who are collaborating on the still embryonic UL4600…

So, how does UL 4600 differ from SOTIF (also known as ISO 21448)?

Phil Koopman, professor in Electrical and Computer Engineering at Carnegie Mellon Univ. and CTO of ECR, made it very clear, “UL 4600 is not being developed to supplant SOTIF.”

Riccardo Mariani, Intel Fellow and functional safety technologist, who is active in SOTIF development, agreed.
