5.2 Testing. Testing shall be in accordance with ASTM D 3715 Section 6 with an AQL of 4 percent defective. The sample unit shall be one roll of tape.
5.2.1 Holding Power Test: The holding power test specimen shall be (1/2 inch) 1.27 cm wide, and the area of test on the panel shall be a (1/2 in.) 1.27 cm by (1/2 in.) 1.27 cm square area. The test shall be performed at 49 degrees Celsius using a 500-g load. Both sides of the tape shall be tested. The specimen shall be prepared for the face side test by removing the liner and adhering the tape liner side to a 1-mil thick polyester film and then cutting a (1/2 inch) 1.27 cm wide specimen. The specimen fot the liner side test shall be prepared by first adhering the tape face side to a 1-mil thick polyester film. The liner shall then be removed and a (1/2 inch) 1.27 cm wide specimen cut.
5.2.2 1/ Accelerated Aging: (Type I tape only)- Two specimens per test roll are required. Each specimen shall be at least (1/2 inch) 1.27 cm wide and (10 inches) 25.4 cm long. Place (4 inches) 10.16 cm of one specimen, adhesive side down, on a glass plate. Superimpose on each another specimen, adhesive. Side down, with the end projecting over the glass plate to serve as a starting tab. The starting tab is formed by doubling the adhesive side of the tape on itself. Arrange multiple specimens so that there is a free air space around them. Place a second glass plate over these strips. Add a 1,000 gram weight on the upper glass plate, place in a container and environment described in ASTM D 3611, and place the assembly from the oven at the end of 30 hours, remove the weight and upper glass plate, and expose the remainder to a temperature of 23 (2 degree Celsius) and a relative humidity of 50 + 2 percent until equilibrium is achieved. Remove the superimposed tape, and observe and report as a failure any adhesive stringiness or offsetting and any tearing or delamination of the backing. Perform the test for adhesion and adhesion to liner.
6. Packaging: Preservation, packing, and marking shall be as specified in the contract or order.
