NOTE
A ripcord-locking pin should withstand a 7-pound load without
assuming a permanent set.
c. Remove the weight, rotate the locking pin one-quarter turn, and test the pin again by reapplying
the load as prescribed in step b., above.
d. Repeat the procedure is step c., above, until the locking pin has been tested in four positions and
rotated one-quarter turn prior to each test.
NOTE
Each locking pin on a ripcord length will be tested under load in four
positions.
e. Remove the weight from the ripcord grip and further remove the locking pin from the test block.
f.
Visually, examine the test block locking pin to ascertain if it is marred, cracked, or distorted during
the test under load. If any defects are noted, the ripcord will be removed from service.
g. Repeat the procedures in steps b. through f. above, for the remaining locking pins on the ripcord
length. After testing all the locking pins, if there are no visual defects apparent, each of the
locking pins will then be further tested for bends.
h. Place a locking pin in a vertical position with the pin end facing upward and either clamp the pin
between two wooden blocks at a point below the pin or hold between the thumb an index finger of
one hand.
i.
Using a test gage block, manually locate the hole in the block over the end of the secured pin,
allowing for a 1/16-inch maximum insertion.
