7.2 Test Method for Edge Waving of Tape
The edge waving of tape shall be tested in such a manner that one end of tape
is xed, the tape is pulled by a force of 1N (102 gf) applied to the other end, a
graduated transparent plastic plate which also serves as a weight is placed on the
tape, and then the waving is measured.

7.6 Strength of Carrier and Cover Tapes
Carrier Tape
When a tensile force of 10 N (1.02 kgf) is applied in the direction of unreeling
the tape, the tape shall withstand this force.
Cover Tape
When a tensile force of 10 N (1.02 kgf) is applied to the tape, the tape shall
withstand this force.
7.7 Peel Strength of Cover Tape
The direction of the cover tape peeling force should be maintained at an angle of
165 to 180 degrees.
When the cover tape is peeled off at the speed of 300 mm/min ± 10 mm/min, the
cover tape peeling force should be 0.1 to 0.7 N (10.2 to 71.4 gf).
