Step 8 - For each BOF tube that will not be connected to a single tube BOF cable, end seal the BOF tube using a BOF tube coupler and a BOF tube fitting plug in accordance with Method 2J1 of this standard.

Step 9 - Access the single tube BOF cables that are to be connected to the multiple-tube BOF cable within the compartment. Select one cable and measure approximately 3.8 cm (1.5 in) from the end of the single tube BOF cable and mark the outer jacket. With the cable jacket-stripping tool, ring cut and remove the single tube BOF cable outer jacket up to the mark.

NOTE: Make sure that the individual tube is not cut, punctured, crushed, or kinked while removing the single tube BOF cable jacket.

Step 10 -Trim back any strength members or waterblocking tape around the BOF

tube flush to the BOF cable jacket edge.

Step 11 -Use the tube cutter to trim approximately 16 mm (0.6 in) off the end of the BOF tube. Visually verify that the end of the tube is cut perpendicular to the tube length.

Step 12 -Abrade the end of each single tube cable jacket circumferentially over the length that will be in contact with the shrink tube using emery cloth. Clean the end of the single tube BOF cable jacket with a wipe dampened with alcohol and blow dry as necessary.

Step 13 -Cut a 127 mm (5.0 in) length of heat shrink sleeve (in accordance with the diameter in table 1D1-IV). Slide the heat shrink sleeve over the single tube BOF cable.

NOTE: The heat shrink sleeve material shall meet the requirements SAE AMS- DTL-23053/15 and table 1D1-IV.

NOTE: A cold shrink sleeve may be used in lieu of a heat shrink sleeve.
