(Specification)Standard Specification for Inserted and Noninserted Surgical Scissors
Standard Specification for Inserted and Noninserted Surgical Scissors
ABSTRACT
This specification covers the general workmanship aspects of inserted and noninserted 410, 410K, 416, 420, 420A, and 420B martensitic stainless steel scissors intended for reuse in surgery. Inserts should be made of stellite, tungsten carbide, or other suitable materials. The instruments should conform to the required values of corrosion resistance cutting ability, Rockwell hardness, and physical properties after passivation and heat treatment. The products should also have finger rings, joints, cutting edges, pivot screws, and finish that are of the required quality.
SCOPE
1.1 This specification covers general workmanship aspects of inserted and noninserted stainless steel scissors fabricated from stainless steel and intended for reuse in surgery.
1.2 The following safety hazards caveat pertains only to the test method described in this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
