Underwriters Laboratories’ (UL) 94 Standard for Safety Tests for Flammability of Plastic Materials for Parts in Devices and Appliances defines acceptable flammability ratings of plastic materials for parts in devices and appliances in North America. The First Edition of UL 94 appeared in September of 1972. And on September 16, 1988, the Department of Defense (DoD) adopted UL 94. Since then, there have been several updated editions of UL 94.
