ASTM D903 Test Specimen

ASTM D903 Test Specimen

Test specimens used in ASTM D903 (Peel or Stripping Strength of Adhesive Bonds). Each test specimen consists of two pieces of flexible material (1" x 12" and 1" x 8") bonded for 6" at one end. The test requires ten specimens for each tested adhesive. The test material depends on the end-use application, but this method can be used for metals and plastics (1/6" thick), wood (1/8" thick), rubber (0.075" thick), and cotton duck canvas.
