Scope
This document specifies test methods for grasping force and durability of repetitive grasping of externally powered prosthetic hands used to substitute for wholly or in part of absent or deficient hand.
The grasping motions covered by this document are
— cylindrical grasp,
— pinch grip,
— lateral pinch.
This document does not apply to body-powered prosthetic hands, cosmetic hands, passive hands, and finger prostheses.
This document does not cover a myo-electric sensor to measure myopotential from residual muscles.
Purpose
Externally powered prosthetic hands, which is called as electric hands, have been used for a long time. Recently, a variety of electric hands using various materials and technologies (e.g., 3D printing) have been released to the market. Therefore, a standard to test the performance of electric hands is necessary for evaluating the electric hands.
