Testing Procedure
1. The helmet shall be positioned
2.In this position the helmet shall be held at a point traversed by the vertical axis passing through the centre of gravity of the headform is equipped with a load bearing device aligned with the vertical axis passing through the centre of gravity of the headform and with a device to measure the vertical displacment of the point of application of the force
3.A guide and arrest device for a falling mass shall then be attacheed below the headform, the mass of the headform so equipped in this ways shall be 15±0.5kg, this produces the preloading on the retention system for determiniing theh position form which the vertical displacment of the point of application of the force hall be measured
4.The falling mass of 10kg±0.1kg shall then be released and shall drop in a guided free fall from a height of 750mm±5mm
