Abstract: A force generator applying a force load against a facemask. A first load cell carrying a first portion of the facemask at an attachment point of the facemask where the facemask is attachable to a helmet. A second load cell carrying a second portion of the facemask at another attachment point of the facemask where the facemask is attachable to a helmet. A first attachment platform carrying the first load cell, wherein the first attachment platform is laterally movable in at least two degrees of freedom. A second attachment platform carrying the second load cell, wherein the second attachment platform is laterally movable in at least two degrees of freedom. The force generator directs the contact plate against the facemask to cause a horizontal deformation of the facemask and a lateral movement of the attachment platforms to allow for repeatable force load testing on a single facemask.
