Testing shall be in accordance with ASTM D 3 7 15 Section 6 with an AQL of 4 percent defective. The sample unit shall be o
12、ne 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 s
13、haU 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 for the liner side test shall be prepared by first adhering the tape face side
14、 to a 1-mil thick polyester lm, The liner shall then be removed and a (112 inch) 1.27 cm wide specimen cut. 5.2.2 L/ Accelerated Apinp: (Type I tape only) - Two specimens per test roll are required. Each specimen shall be at least (112 inch) 1.27 cm wide and (10 inches) 25.4 cm long. Place (4 inches
15、) 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 specim
16、ens so that there is a fiee 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 36 1 1, and place the assembly in a 49 (1 degree Celsius) oven. Remove assembly from the oven at
17、 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 i 2 percent until equilibrium is achieved. Remove the superimposed tape, and observe and report as a failure any adhesive stringiness or off
18、setting and any tearing or delamination of the backing. Perform the test for adhesion and adhesion to limer. 6.
