This sheet of IEC 60454-3 contains the requirements for pressure-sensitive adhesive tapes,made with combined backings based on polyester film:– PET film/glass filament combination tapes;– Creped cellulosic paper/PET film combination tapes;– PET film/polyester non-woven combination tapes;– PET film/epoxy combination tapes.Materials which conform to this specification meet established levels of performance. However,the selection of a material by a user for a specific application should be based on the actualrequirements necessary for adequate performance in that application, and not based on thisspecification alone.
