>From IEC 74/510/CD, draft amendment to IEC 60950, Material flammability classifications, HBF replaced by FH-3. "The new definitions are not in all cases identical to the earlier ones."
I imagine the -40 in the FH3-40 you refer to is the burning rate of 40mm/min specified for HBF. A certain national committee, not too many miles from Dundee, commented on this proposal that we "welcome the proposal in principle. However, in view of the widespread use of UL-recognized materials, (we) would not support the proposal being advanced to a CDV until it is agreed that IEC-rated and UL-rated materials are accepted by test houses world-wide as equivalent and interchangeable" John Crabb, Development Excellence (Product Safety) , NCR Financial Solutions Group Ltd., Kingsway West, Dundee, Scotland.
