25、5 mm) of one end of the sleeving shall be pressed together with sufficient pressure from the pair of pliers so the surfaces are in full contact and the pressure held for 20 to 40 seconds. Allow the sleeving to condition at room temperature for 10 minutes. Reheat the sleeving in a 302 F (150 C) oven
26、for 5 minutes. Remove from the oven and allow the sleeving to condition to room temperature for a minimum of 10 minutes. Submerge the pressed together portion of the sleeving 1 inch (2.5 mm) minimum in room temperature water and pressurize the open end of the sleeving at 3 psi minimum for no less th

See 3.5.2 for storage life extension. NOTICE a. Flammability
30、- Class 1 shrinkable sleevings described in this specification sheet have not been flame retarded and will burn readily. These sleevings shall not be considered for acquisition when flame resistance is required. Additionally, only the outer jacket of Classes 2 and 3 sleevings are flame retardant. In
31、tended use: Heat shrinkable dual-wall polyolefin sleeving is used in one-step potting, encapsulating, or moisture sealing of electrical components.
