The drop height is such that the unit constituted by the headform and helmet falls on the test anvil at a velocity which, immediately before impact, is equal to 8.5 m/s. The rotation-inducing forces caused by projections on the helmet and friction against the outer surface of the helmet which occur when a helmeted headform is dropped vertically on to an inclined anvil are measured in the longitudinal axis of the anvil. visor fittings, studs, etc., and friction with other surfaces. The new test for surface friction measures the rotation-inducing forces created by projections, e.g.The absorption efficiency shall be considered sufficient where the resultant acceleration measured at the center of gravity of the headform (placed inside the helmet to simulate the wearer’s head) at no time exceeds 275 g, and the Head Injury Criterion does not exceed 2400.

The Head Injury Criterion (HIC) is calculated for five specific test points (including the protective chinstrap) using a guided free fall helmet drop test. The impact-absorption test is based on the measurement of the deceleration of a head.Conditioning procedures have been extended to include ultraviolet conditioning and solvent conditioning (for hydrocarbons, cleaning fluids, paints, transfers or other extraneous additions that may affect the shell material).Specific tests for the helmet have been updated and new tests added as follows:

Provisions for child helmets (introduced in 1983 with 2002 series of amendments).Īiroh Terminator Monster: If the helmet is intended to be equipped with a spoiler, peak or vent equipment it will be tested with those items in place. removability, specifications for devices for lifting the visor out of the line of sight with one hand General specifications for the visor, e.g. The extent of peripheral vision (105° from the helmet midline), which should be tested by a field of vision test. For chinstraps there are requirements regarding protection from abrasion, the minimum width of the chinstrap, adjustment devices, positioning of the fastening/tensioning devices, and latching and release of fastening systems. The introduction of shear testing for helmet shell surface irregularities of over 2 mm in height, requirements to smooth projections, and controls on the interior surface of the helmet shell (i.e. The same requirements remain in effect for hearing and ventilation. Much more detailed requirements concerning the extent of the helmet’s head coverage. Requirements on the basic structure, visors, peaks and the need to identify non-protective chinstraps. No contact between striker tip and support surface 
Peak rotational acceleration ≤10400 rad/s 2 (2020: goes to ≤8000 rad/s 2). Peak linear acceleration ≤208 g (goes to ≤160 g in 2020). The lower the value, the higher the helmet’s performance.) HIC ≤2400 (HIC is “head injury criterion” used to quantify the likelihood of head injury resulting from sudden deceleration and impact force. Peak linear acceleration ≤275 g (g = force caused by acceleration/deceleration-less is best inside your lid). 
Performance Thresholds under FIM Standards: Samples #1 and #2 (Linear impact)
2 penetration sites, above the Snell “test line”, at least 75 mm separated. In addition, a penetration test is included in the protocol and used to check the shell resistance to impacts against sharp objects. The test is intended to impart rotational force and measure its severity as transferred to the headform inside the helmet. As defined in UNECE 22.05 (Impact-absorption test), with: platinum cure silicone coated headform (µ = 0.78), “oblique anvil”: 45º plane, abrasive paper to be substituted after significant damage, impact velocity 8.00 (+0.15, -0.00) m/s.
