Craig is correct - the UL1950 PAG 4.4.4-002 confirms this and adds, "IEC TC74 is developing a proposal to clarity this issue."

This relaxation is considered acceptable for ITE. According to UL, a Recognized Component material with either a 94-5VA or 94-5VB flammability rating is considered to meet the Class 5V material flammability requirement. This same interpretation should hold true for material classified as 5V per EN69050. Happy Holidays, Craig Hensley Iomega Corp.

Is there a difference between these two rating and which one is equivalent to the EN60950 classification 5V. Thanks in advance, <<...>> William D'Orazio CAE Electronics Ltd.
