Full title and description
ASTM F1079-87 (Reapproved 2022) — Standard Specification for Inserted and Noninserted Surgical Scissors. This specification defines workmanship, materials, heat treatment, passivation, hardness, corrosion resistance and performance requirements for inserted and noninserted stainless‑steel scissors intended for reuse in surgery.
Abstract
This specification covers general workmanship aspects of inserted and noninserted scissors fabricated from martensitic stainless steels (common grades: 410, 410K, 416, 420, 420A, 420B) intended for reuse in surgery. It specifies acceptable insert materials (for example stellite or tungsten carbide), Rockwell hardness ranges, passivation and heat‑treatment expectations, corrosion‑resistance and cutting‑ability tests, and quality of rings, joints, cutting edges, pivot screws and finish.

Scope
The standard applies to the general workmanship and basic material/performance requirements of inserted and noninserted stainless‑steel surgical scissors intended for reuse. It does not replace device‑specific regulatory requirements; users are responsible for establishing appropriate safety, health and regulatory practices before use. The standard references test methods and other ASTM specifications for metallurgical and corrosion testing.
Key topics and requirements
- Material: martensitic stainless steels such as 410, 410K, 416, 420, 420A and 420B for scissor components.
- Inserts: acceptable insert materials include stellite, tungsten carbide or other suitable materials for inserted scissors.
- Hardness: Rockwell hardness requirements for scissor halves and inserts (typical range specified around 40–58 HRC; limits on hardness variation between halves).
- Heat treatment and passivation: instruments and components shall be heat treated per material recommendations and passivated after fabrication/finishing (reference to Practice A380 for passivation guidance).
- Performance tests: corrosion resistance and cutting‑ability tests are specified (references include Test Method F1089 for corrosion and specified cutting‑ability procedures).
- Workmanship and finish: requirements for finger rings, joints, cutting edges, pivot screws and overall finish to ensure functional and re‑usable surgical instruments.
These topics and numerical/technical limits are summarized in the specification text.
Typical use and users
Manufacturers and designers of surgical scissors, quality assurance and inspection teams, hospital sterile processing departments, procurement specialists, and regulatory or testing laboratories use this standard to verify basic material and workmanship characteristics for reusable surgical scissors and to reference the appropriate test methods for hardness, corrosion resistance and cutting performance.
