Standard Specification for Stainless Steel Suture Needle Holders-General Workmanship Requirements and Corresponding Test Methods

ABSTRACT
This specification covers general workmanship and test method requirements of stainless steel suture needle holders intended for reuse in surgery. Materials of all component parts shall be fabricated from martensitic stainless steel type 410, 410X, 416, 420A, 420B, 420C, 420F, 420F Mod, and 440B. The material shall be heat treated and shall conform to the specified hardness, corrosion resistance, workmanship, finish, and appearance.
SCOPE
1.1 This specification covers general workmanship aspects of stainless steel suture needle holders intended for reuse in surgery.
