Step 8 - CAUTION: Do not overheat the BOF cable.  Prolonged exposure of the jacket to temperatures above l60oC (320oF) may damage the BOF cable jacket.        Discontinue heating of the sleeve and allow the BOF cable jacket to cool before reheating if the BOF cable jacket shows any signs of bubbling.

For heat shrink sleeves only:  Holding the heat gun approximately l00 mm (4 in) away from the heat shrink sleeve, shrink the sleeve from the middle to both ends around the entire sleeve.  Heat until the sleeve has shrunk to a snug fit around the splice end pipe and the BOF cable, and the sealant is flowing at the ends.

For cold shrink sleeves only:  Remove the sleeve center support and allow the sleeve to shrink into place.

Step 9 - Repeat steps 7 and 8 for the other end of the splice.

Step l0 -Abrade each short shrink sleeve circumferentially over the length that will be in contact with the long shrink sleeve using emery cloth.

Clean the end of each of the short shrink sleeves with a wipe dampened with alcohol and blow dry as necessary.

Step ll -Slide the long shrink sleeve up the BOF cable.  The sleeve should be placed so that it is approximately centered over the splice.

Step l2 -For heat shrink sleeves only:  Holding the heat gun approximately l00 mm (4 in) away from the heat shrink sleeve, shrink the sleeve from the middle to both ends around the entire sleeve.  Heat until the sleeve has shrunk to a snug fit around the BOF cable splice, and the sealant is flowing at the ends (see figure lCl-5).

For cold shrink sleeves only:  Remove the sleeve center support and allow the sleeve to shrink into place.

Step l3 -Verify the continuity of each spliced tube with a ball bearing using method 6Hl of this standard.

NOTE:        Alternatively, the continuity of each spliced tube may be verified prior to assembling the splice body.
