MIL-STD-2042-6B(SH)

NOTE: This can be accomplished by applying pressure to the near end of the

BOF tube to be tested and observing air flow at the tube remote end.

344 to 688 kPa (50 to 100 PSI) should be sufficient to allow tube

verification.

Step 4 - Place a BB into the BOF tube under test.

Step 5 - Using the pressure source, send the BB through the tube. Use the projectile trap to catch the BB as it exits the tube.

NOTE: A pressure of 344 to 688 kPa (50 to 100 PSI) should be sufficient to send the BB through the BOF tube.

Step 6 - If the BB exits the BOF tube, proceed to step 8. If the BB does not exit the BOF tube, proceed to step 7.

Step 7 - Apply pressure at the remote end of the tube and remove the BB.

Record the test failure on the test data sheet.

NOTE: Do not exceed 1034 kPa (150 PSI) within the BOF tube when attempting to dislodge a stuck BB. BOF tube damage can occur at pressures greater than 1034 kPa (150 PSI).

NOTE: A BB stuck within a BOF tube can also be dislodged by injecting a BB with a diameter smaller than 4.5 mm (0.17 in) from the remote end of the BOF tube.

Step 8 - Repeat steps 2 through 7 for all of the tubes to be tested.
