In those cases where a sustained peel cannot be obt
15、ained 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 less than 4.0 mm thick and a numerical ply adhesion value cannot be satisfactorily obtained
16、, ply adhesion shall be acceptable if the fabric cannot be separated cleanly from the foam.
