14、ticles adhered to the peeled surface). In those cases where a sustained peel cannot be obtained due to the foam tearing or breaking away completely from the fabric, ply adhesion shall be considered acceptable if the peak load prior to break exceeds the above minimum requirement. If the laminate is l

15、ess than 4.0 mm thick and a numerical ply adhesion value cannot be satisfactorily obtained, ply adhesion shall be acceptable if the fabric cannot be separated cleanly from the foam.
