Endurance tests

Laboratory freezers can be used for various endurance tests. In this special case the helmet first gets cooled down and then it is hit with blocks of various weight and shape. In this way you can check the material the helmet has been made of. As a consequence, you can choose the most optimal material for certain conditions. The helmets tested in this way can be used, for example, by workers at oil platfroms in north Russia, where the ambient temperature is extremely low.
