Ultra - Voilet Conditioning Chamber
Helmets are subjected to conditioning under different atmospheric conditions before they are subjected to the impact absorption test. One of these conditions involves exposure to ultraviolet radiations, followed by spraying of water on top of the helmets. This conditioning can be carried out in a special chamber having provision for exposing the helmet to ultraviolet radiations, followed by spraying it with water from a spray nozzle.
