Knowledge of UL Testing:
UL 94 Flammability Testing:
UL 94 small-scale test data is intended solely for determining the
flammability of plastic materials used in the components and parts of
end-use product devices and appliances, where the acceptability of the
combination is determined by UL Inc. By small-scale tests, materials
are classified as V-0, V-1, V-2, HB In addition, some materials may
also secondarily be classified as 5VA or 5VB.
UL 746B Long-Term Heat Aging:
The materials covered by this program have, in many cases, been
investigated with respect to retention of certain critical properties
(e.g. dielectric, tensile, impact, and the like) as part of a longtime
thermal-aging program conducted in accordance with Underwriters
Laboratories Inc. "Standard for Polymeric Materials-Long Term Property
Evaluations" ,UL 746B.
