Mechanical testing of prosthetic sockets — Requirements and test methods

Scope

This Technical Specification will define principles, terminology, test setups, and test methods for the
mechanical strength and durability testing of prosthetic sockets, with initial focus on transtibial
prosthetic sockets.
The document will provide guidance for:
● Shape, composition, fabrication and use of mock residual limbs for mechanical testing
● Requirements for test specimens and interface components
● Test sample coordinate systems and alignment
● Static and fatigue loading conditions
● Preliminary guidance for acceptance criteria and reporting
This document will not define user-specific clinical prescriptions, component selection, or manufacturing
processes nor will it be limited to one line of inquiry on the best type of testing protocol. It is intended as a
Technical Specification due to the ongoing state of technical development and research in this area.
