Flammability rating vw-1
WebVoltage ratings are commonly found on power cables such as extension cords or TV power cables. VW-1: The VW-1 rating written on a cable specifies the flammability of the outer jacket. It is a standardized test to measure how the outer jacket responds when exposed to a flame in a vertical orientation hence the abbreviation VW (vertical wire). The VW-1 (vertical wire burn) rating is sometimes erroneously associated with UL 94, but it (and some other flammability tests) is described by UL 1581 (Reference Standard for Electrical Wires, Cables, and Flexible Cords).
