29/1/2014, · The impact test measures acceleration of a headform inside the helmet when it is dropped from a fixed height onto a spherical and flat surfaced anvil. The standard allows peak acceleration energy of 400G (G being “gravity constant” or an acceleration value of ft. per second x seconds).

For impact testing, the typical test apparatus consists of a rig that drops a helmeted headform in a guided freefall to an anvil on the floor. You strap the helmet on the headform, turn it upside down so the helmet hits the anvil first and drop it onto the anvil. The helmet is oriented before each drop to test it's most vulnerable areas.
