Strength and penetration are key attributes needed for surgical needles. ASTM International standard, ASTM F3014, Test Method for Penetration Testing of Needles Used in Surgical Sutures, focuses on penetration testing of such needles. Having low and consistent penetration force provides users with control for accurate placement of surgical needle during procedure, especially when there is limited space in which to maneuver needle, and when thick or hard tissue is encountered.
