9/2/2005, · (Figure 3.: A moment after the drop ,test, of riding ,helmet,) Before the complete ,test, process first had to be checked the effectiveness of the mitigation of the used padding materials of ,helmet, at ,impact test, and had to be chosen the more suitable bed material. The material of the padding was polystyrene with different density.
Biokinetics' ,helmet impact, tower (HIT) is used to evaluate the ,impact, performance of ,helmets, across a range of ,test, conditions specified in standards such as the ASTM, CPSC, DoT, ECE and Snell. The self-supporting tower consists of a pedestal, linear bearing rail, lift carriage, drop carriage and lift motor.
If the ,helmet, works well, the g's are low--probably below 200, and in the better ,helmets, below 150. If the g's exceed 300, the ,helmet, fails. The ,testing, is on three anvils of different shapes: The flat anvil is used with a 2 meter drop. The ,helmet, and headform are traveling at 14 mph at ,impact,.
The ,test, method specifies different ,impact, locations on the ,helmet,, all of which result in impacts to the centre of gravity in the dummy head (NOCSAE, 2006). Rousseau et al. (2011) have proposed a modification of the ,test, method by hitting the ,helmet, at directions that are offset from the centre of gravity of the head to simulate real impacts as seen in football and ice hockey games.
Welcome to SHARP, the Safety ,Helmet, Assessment and Rating Programme, a scheme to help motorcyclists make an informed choice when buying a ,helmet,. SHARP provides advice on how to select a ,helmet, that fits correctly and is comfortable, and information about the relative safety of ,helmets, to help motorcyclists to make an informed choice.
Each ,helmet, sample was subjected to a total of 24 ,impact, tests comprising the full combination of 3 ,test, speeds and 8 ,impact, locations. The ,test, speeds were 5.5 m/s, 7.4 m/s, and 9.3 m/s, with a tolerance of ± 0.1 m/s. The standard protocol was to ,test, 2 samples of each ,helmet, model.

The drop tower ,test, is the industry standard for ,helmet testing,. In this ,test,, a twin-wire impactor simulates ,helmet,-to-,helmet impact,. To ,test, the shock absorbency , ,helmets, get taken to a height of 60 inches from the ground, then dropped onto a steel anvil beneath a firm rubber pad at specific velocities, locations and temperatures.
Helmet Testing Equipment, Manufacturer of a wide range of products which include audibility ,test, apparatus, ,impact, absorption tester, 20 kn flammability tester, humidity chamber, moisture conditioning chamber for ,helmet, and crimp rigidity tester.
