The ,Helmet, Mounted Cough Guard can be fitted to a JSP ,helmet, to reduce the likelihood of exhaled bacteria/virus contacting the wearer's face. This product does not meet the requirements of EN166 (including splash protection or ,impact, protection). This product is not PPE as defined by the EU PPE Regulation 2016/425.
1/5/2016, · The impact conditions of the bike helmet depend on the speed that the rider reaches the floor when hitting the head. The analysis considers three speeds: 7m/s, 8.5m/s, and 10m/s. In this case, the rider speed impact to the floor is the driver for this analysis. Impact speeds of riders during different types of impact can be obtained from crash data.
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 ...
A head form is mounted on a stand so that it points face downward at an angle of 135 degrees. The helmet is placed on the head form and the straps and buckles adjusted to obtain a "best fit". A wire rope is hooked to the rear edge of the helmet and brought forward so that its free end runs across the helmet and downward towards the floor.
9/2/2005, · The height of the ,helmet impact, point from the anvil surface was constant at every drop test: 2000 +/- 3 mm. The anvil surface was flat. Additionally between the flat surface and the 550 kg mass of base was placed a special force transducer, designed with strain gauges, calibrated for 0-25 kN.
The ,impact, energy (drop height and mass), or how hard the ,helmets, are impacted is unique to each standard. However, in any valid test, if the peak acceleration imparted to the head form exceeds certain threshold value (around 260-300 G's, depending on standard and test type), the ,helmet, is rejected.

Helmets designed to handle major crash energy generally contain a layer of crushable foam. When you crash and hit a hard surface, the foam part of a helmet crushes, controlling the crash energy and extending your head's stopping time by about six thousandths of a second (6 ms) to reduce the peak impact to the brain.
