7、Loadings at the test displacements must conform to the requirements as specified on the Engineering Drawing. Test method: . Place the product on a matrix that matches the surface contour of the bottom side of the part. Test area shall be put in horizontal position. Use an 80 mm diameter indentor. .

8、Apply a force (preload) of 5 N to the test area as indicated on the Engineering Drawing and zero the load scale and displacement scale. . Indent the product to the first displacement as shown on the Engineering Drawing at a rate of 100 +/- 20 mm/minute. After reaching this indentation, release the l

9、oad at the same rate. Repeat this loading and unloading twice. . Immediately after the third unloading indent the product to the third displacement as shown on the Engineering Drawing and maintain for 30 s. Measure the force (N). 3.6 PEEL ADHESION, N/50 mm, min, (FLTM BN 151-05, Method “A“, specimen
