Suture retention force¡ª Cut representative 1 ¡Á 1 cm test specimens from final product lots. Using an appropriate suture material (e.g., 4 0 polypropylene suture), thread the suture 3 mm from the edge of the sample in the center and pull through. Clamp approximately 5 mm of the opposite, unsutured end of the test specimen in the upper pneumatic grip of a commercially available material test system.8 The suture tails are hanging freely. Clamp the suture tails to the lower grip. Pull the grips apart at 20 mm per minute while concurrently measuring the force exerted. Record the maximum force (N) measured. The suture retention force measured for each lot is not less than 5 N for a 1 ¡Á 1 cm test sample of the Bovine Acellular Dermal Matrix.
