Impact testing, is the process of ,testing, the amount of force our cricket ,helmets, deflect and then absorb under ,test, conditions. Over the years we have built up a great deal of knowledge and understanding ensuring that every protection product that leaves us gives the player the best protection possible.
Founded in 2005, GSP Superb Technology India is a professional manufacturer of ,helmet testing, machines, hardness testers and other laboratory equipment. Our ,testing, machines and equipment are highly engineered and sturdy, thanks to the new-age progressive production techniques and strict quality standards employed right through all the phases of design and manufacturing.
Bicycle ,Helmet, Ratings. In collaboration with the Insurance Institute for Highway Safety, we have rated a total of 106 bike ,helmets, using the STAR evaluation system.Our bicycle ,helmet impact, tests evaluate a ,helmet's, ability to reduce linear acceleration and rotational velocity of the head resulting from a range of impacts a cyclist might experience. . ,Helmets, with more stars provide a ...
After the release of the ,Helmet, Laboratory ,Testing, Performance Results in April 2020, ... coordinated extensive laboratory research to evaluate which ,helmets, best reduce head ,impact, severity. The results of the laboratory tests are displayed on the poster below and shared with NFL players, ...
Alter the part of the ,helmet, that hits the ground first (the top of the ,helmet, vs the side of the ,helmet,) to see what type of ,impact, causes the most damage in a crash. ,Test, new ,helmets, versus old ,helmets, to see if the age of a ,helmet, makes a difference in how well it protects your head.
The ,Helmet Impact Test, System (HITS) is designed to ,test, the performance of industrial ,helmets,. In order to operate the device, you need a mechanism for dropping a weight (drop tower), a ,test, floor/platform to which the device base will be bolted, and signal conditioning and re- cording equipment for a minimum of six data channels.
Testing, standards differ between organizations but generally include ,impact, and retention tests. During ,impact testing,, ,helmets, are dropped from a certain height onto a metal object. The force transferred to the inside of the ,helmet, upon ,impact, is measured using a computer.
The European ski and snowboard standard. EN-1077, requires that ,helmets, undergo ,impact testing,, though its protocols are not as severe in some ways as those required by some other standards. There are two variations of EN-1077 (Class A and Class B). Of the two, Class A demands greater coverage and penetration resistance.
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.
The DRI ,Impact Test, Laboratory is an ISO 17025 accredited ,test, lab and utilizes the most sophisticated ,impact test, systems available for ,helmet, R&D, quality control, or accident reconstruction studies. We have the capacity to perform ,testing, to US motorcycle and bicycle ,helmet, standards as well as many international ,helmet, standards.
