What is the shelf life of a ,helmet, and what is the expiry date? - According to the Singapore SS 98 standard for industrial ,safety helmet, specification, there is no manditory expiry date.Instead, representative samples from each batch of hats can be tested every 3 years (from the date of first use) to ensure each batch's compliance with SS 98.
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.
There are two distinct methods of testing football helmets. Drop Tower Test. 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.

In collaboration with the Insurance Institute for Highway Safety, we have rated a total of 104 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 …
29/1/2014, · ,Testing, Methods: 1. ,Impact, Absorption ,Test,: Principle ,Impact, absorption capacity is determined by recording against time the acceleration imparted to a headform fitted with the ,helmet,, when dropped in guided free fail at a specified ,impact, velocity upon a fixed steel anvil. The first ,impact, shall be carried out within 45 seconds of conditioning.
Impact Testing – he impact test uses controlled impacts to simulate different impact surfaces. The object is to measure gravitational (G) force or acceleration. If the peak acceleration in any test exceeds a value, the helmet is rejected.
