HIGHLIGHTS OF THE STANDARD: ASTM F3109-16
  • specifies procedures for performance verification of multi-axis force platforms commonly used for measuring ground reaction forces during gait, balance and other activities.
  • provides a method to quantify the relationship between applied input force and force platform output signals across the manufacturer’s defined spatial working surface and specified force operating range.
  • provides definitions of the critical parameters necessary to quantify the behavior of multi-axis force measuring platforms and the methods to measure the parameters.
  • presents methods for the quantification of spatially distributed errors and absolute measuring performance of the force platform at discrete spatial intervals and discrete force levels on the working surface of the platform.
  • further defines certain important derived parameters, notably COP (center of pressure) and methods to quantify and report the measuring performance of such derived parameters at spatial intervals and force levels across the working range of the force platform.
  • defines the requirements for a report suitable to characterize the force platform’s performance and provide traceable documentation to be distributed by the manufacturer or calibration facility to the users of such platforms.
  • written for purposes of multi-axis force platform verification; however the methods and procedures are applicable to calibration of force platforms by manufacturers.

The ASTM F3109-16 standard establishes a global precedence for force plate verification. Force plate verification is critical for the user and ensures quality of measurement. With applications in human performance research and gait analysis, surgeons, physicians, and physical therapists rely on the data from force plates to make medical decisions.
