1.1 This specification covers characterization of the design and mechanical function of metallic staples used in the internal fixation of the musculoskeletal system. It is not the intention of this specification to describe or specify specific designs for metallic bone staples. 1.2 This specification includes the following four test methods for measuring mechanical properties of metallic bone staples: 1.2.1 Test Method for Constant Amplitude Bending Fatigue Tests of Metallic Bone Staples—Annex A1. 1.2.2 Test Method for Pull-Out Fixation Strength of Metallic Bone Staples—Annex A2. 1.2.3 Test Method for Soft Tissue Fixation Strength of Metallic Bone Staples—Annex A3. 1.2.4 Test Method for Elastic Static Bending of Metallic Bone Staples—Annex A4. 1.3 The values stated in SI units are to be regarded as standard. Any other units of measurement included in this standard are shown for reference only. 1.4 Multiple test methods are included in this standard. However, the user is not necessar
