4.5.2.2 Tape ultimate strength tests. A test specimen, 15 feet long, shall be obtained as
specified in 4.5.2.3. The specimen shall be load tested.
4.5.2.3 Method of sampling for breaking strength tests. The first section of tape leaving a
loom run shall have a 15-foot specimen removed from the lead end. After this, a 15-foot
specimen shall be removed immediately following every other, or alternate, production tape.
The rolls of tape shall be marked consecutively as they leave the loom, with the 15-foot
specimens marked identically with the rolls of tape to which they apply. Test the first 15-foot
specimen leaving the loom run and every 15-foot specimen thereafter. For example, the three
15-foot specimens are tested as outlined in 4.5.2.2. Then, the tests may result in one of the
following seven possibilities as specified in 4.5.2.3.1 through 4.5.2.3.7 (see figure 3).

4.5.2.3.1 Test result I. If the three tape specimens pass the strength test, the four production
tapes in between them are satisfactory.
4.5.2.3.2 Test result II. If the first specimen leaving the loom run fails the strength test and
the other two specimens pass the strength test, the third and fourth production tapes are
satisfactory, but a 15-foot specimen shall then be cut from the lead end of the first production
tape and tested in order to determine if the first and second tapes are satisfactory. If this
specimen passes, the first and second production tapes are satisfactory. If the specimen fails, the
first production tape is unsatisfactory. A 15-foot specimen shall then be cut from the trailing end
of the first production tape in order to determine if the second production tape is satisfactory.
4.5.2.3.3 Test result III. If the second specimen fails and the first and third pass the strength
test, a 15-foot specimen shall be taken from the trailing end of the second production tape and
