21、r Ducts and Air Connectors, UL 181. 1.2 These requirements cover only pressure-sensitive tapes intended for use at the core to tting attachment and at the outer moisture barrier. When used at the core to tting attachment, a mechanical fastener shall be installed over the tape. The tape shall be empl

When tape is used at the outer moisture barrier, mechanical fasteners may or may not be employed. 1.3 These requirements cover only mastic systems intended to be used with joints of factory-made exible non
23、-metallic air ducts or air connectors which employ mechanical fasteners (see 2.4). The joints, without mastics, shall comply with the requirements of the Standard for Factory-Made Air Ducts and Air Connectors, UL 181. 1.4 Mastic closure systems are intended for use as an additional seal at the attac
24、hment of the exible non-metallic air duct cores (or air connectors). The mastic shall be installed uniformly around the mating surface of the tting collar (i.e. sleeves, elbows, and the like) and in such a manner that it does not disrupt the connection of the mechanical fastener around the core. 1.5
