TYPE OF TESTING
IMPACT TEST
This test involves a series of controlled impacts where a helmet is positioned on a metal head form and then dropped in a guided fall onto various steel test anvils (Flat, Hemisphere, Kurbstone, Roll bar, Edge or a Horseshoe type) which simulate different impact surfaces. The head forms are instrumented with an accelerometer to measure peak G force or acceleration which is measured in “G”ravitational units. 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 300 G’s, depending on standard and test type), the helmet is rejected.
POSITIONAL STABILITY (ROLL-OFF) TEST
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. The free end of the rope has a mechanical stop with a 4 kg weight resting on the stop. The weight is raised to a prescribed height and dropped onto the stop. The resulting shock places a rotational load on the helmet. The helmet may be shifted, but must not roll off the head form. Next, the head form is rotated 180 degrees, the helmet adjusted, and tested with the wire rope hooked to the front edge of the helmet and the test is repeated. As in the first case, the helmet may be shifted but must not roll off the head form.
DYNAMIC RETENTION TEST
The helmet is placed on a head form and the chin strap fastened under a device approximating the contour of the jaw. The jaw piece is loaded with a 23 kg weight for approximately one minute. The retention system is tested by simultaneously removing the 23 kg weight and applying a 38 kg mass in an abrupt guided fall. The retention system fails if it cannot support the mechanical loads or if the maximum instantaneous deflection (stretch) of the retention system exceeds 30 mm. Drop heights for the 38 kg mass are different for each standard, however the mechanism and failure criteria are similar for other types of headgear.
CHIN BAR TEST
The chin bar test applies to full face motorcycle, special application racing and kart racing helmets. The helmet is affixed to a rigid base with the chin bar facing upward. A 5 kg weight is dropped through a guided fall to strike the central portion of the chin bar. Maximum downward deflection of the chin bar must not exceed the stated distance.
SHELL PENETRATION TEST
The shell penetration test applies to motorcycle, special application racing, kart racing, skiing and equestrian helmets. The helmet is affixed to a rigid base. A 3 kg sharply pointed striker is dropped in a guided fall onto the helmet from a prescribed height. The test striker must not penetrate the helmet or even achieve momentary contact with the head form.
FACESHIELD PENETRATION TEST
The face shield penetration test applies to full face motorcycle, special application racing and kart racing helmets. The face shield is affixed to the helmet and shot along the center line in three separate places with an air rifle using a sharp soft lead pellet. Pellet speed will be approximately 500 kph. For both types of shield the pellet must not penetrate, and for the racing helmet any resulting “bump” on the inside of the shield must not exceed 2.5 mm.
FLAME RESISTANCE TEST
The flame resistance test applies to special application racing helmets only. The test is conducted using a propane flame of approximately 790 degrees centigrade. The flame is applied to the shell, trim, chin strap and face shield for a specified number of seconds, and any resulting fire must self extinguish within a specified time after flame removal. During the whole process the temperature of the interior lining of the helmet must not exceed 70 degrees centigrade.
