Prosthetics - Testing of ankle-foot devices and foot units - Requirements and methods (ISO 22675:2006)
IMPORTANT This International Standard is suitable for the assessment of the conformity of
prosthetic ankle-foot devices and foot units with the strength requirements specified in 4.4 of
ISO 22523:2006 (see NOTE 1). Prosthetic ankle-foot devices and foot units on the market, which have
demonstrated their compliance with the strength requirements specified in 4.4 of EN 12523:1999
through submission to the relevant tests of ISO 10328:1996, need not be retested to this International
Standard.
WARNING This International Standard is not suitable to serve as a guide for the selection of a
specific ankle-foot device or foot unit in the prescription of an individual lower limb prosthesis! Any
disregard of this warning can result in a safety risk for amputees.
This International Standard primarily specifies a cyclic test procedure for ankle-foot devices and foot units of
external lower limb prostheses, distinguished by the potential to realistically simulate those loading conditions
of the complete stance phase of walking from heel strike to toe-off that are relevant to the verification of
performance requirements such as strength, durability and service life.
This potential is of particular importance for the assessment of the performance of a variety of recent designs
of ankle-foot devices and foot units with specific characteristics that will only develop under realistic conditions
of loading.
In addition, this International Standard specifies a static test procedure for prosthetic ankle-foot devices and
foot units, consisting of a static proof test and a static ultimate strength test, distinguished, besides other
features, (see NOTE 2) by the potential to generate heel and forefoot forces at lines of action conforming to
those occurring at the instants of maximum heel and forefoot loading during the cyclic test.
The loading conditions addressed in the third paragraph are characterized by a loading profi (...abbreviated)
