Technical Requirements For FIM Racing Homologation Programme (FRHP)

Until now, the FIM has referred solely to existing international standards for the approval of helmets for use in its competitions.
In order to take account of a more complete and demanding evaluation of performance, and give specific and exclusive recognition to helmets that meet more demanding criteria, the FIM Technical and Circuit Racing Commissions have now launched a pioneering and unique programme, the FIM Racing Homologation Programme for helmets (FRHPhe), which features the latest state of art methods of testing.
Under this programme, the FIM grants helmets a homologation certificate and labels, which are a mandatory prerequisite to be entitled to access FIM Circuit Racing competitions.
To obtain such homologation, the helmet have to meet the high performance and quality standard set by the FIM, in addition to be approved according to selected international standards.
The helmet properties are evaluated through a test protocol which aims to trigger the development of helmets offering an optimal protection for riders. An optimal protection is understood as providing a minimised risk of skull fracture and of the multiple forms of brain damage, as well as a measured and controlled mechanical performance of the protective padding and the shell.

Eligible Helmets :
UNECE 22.05 Type P
Snell M 2015
JIS T8133 2015 Type 2 Full face
Protective lower face cover: not detachable and not moveable
One-piece shell
Retention system with strap and double D-ring

Sampling :
Samples #1, #2 and #3: Conditioning, Weight, Linear impact tests
Samples #4 and #5: Conditioning, Weight, Oblique impact tests
Sample #6: Conditioning, Weight, Penetration tests
Sample #7: Storage
Sample #8, #9 and #10: Conditioning, Weight, Extra tests if needed
The helmets are homologated per Size and per declared Combination of accessories (e.g. aerodynamic devices).

Linear Impact :
The FIM test approach first assesses the helmet response to very high and medium-low severity linear impacts, randomly in 13 out of 22 pre-established locations distributed all over the helmet surface. This aims at evenly assessing the level of protection against skull fracture and at featuring the mechanical properties of the protective padding (or liner).

Helmet sample #1 (HIGH SPEED UNECE POINTS)
- As defined in UNECE 22.05 (Impact-absorption test), with flat anvil only
- UNECE points B, X, P, R: 8.2 (+0.15, -0.0) [m/s]
- UNECE point S:6.0 (+0.15, -0.0) [m/s]
Helmet sample #2 (HIGH SPEED EXTRA POINTS)
- As defined in UNECE 22.05 (Impact-absorption test), with flat anvil only
- 3 “extra” points (selected among 12 pre-defined points): 8.2 (+0.15, -0.0) [m/s]
Helmet sample #3 (LOW SPEED UNECE POINTS)
- As defined in UNECE 22.05 (Impact-absorption test), with flat anvil only
- UNECE points B, X, P, R, S: 5.0 (+0.15, -0.0) [m/s]

Oblique Impact :
Innovatively, the FIM test procedure pioneers the assessment of the helmet response to medium severity oblique impacts, aiming at evaluating the level of protection against brain injuries generated by critical rotational accelerations. The oblique test constitutes the most novel and modern aspect of the methods of testing and reflects a very common scenario occurring in real world accidents, although never addressed in international standards so far.
Helmet sample #4 points 45, 180 and 270 degrees
Helmet sample #5: points 0 and 135 degrees
- 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]

Penetration Test :
In addition, a penetration test is included in the protocol and used to check the shell resistance to impacts against sharp objects.
As defined in JIS T8133: 2007 5.2 and 7.5 (Type 2), with:
spherical support
dropping height: 2 [m]
2 penetration sites, above the Snell “test line”, at least 75 [mm] separated

Thresholds :
Samples #1 and #2
Peak linear acceleration ≤ 275 g
HIC ≤2 880

Sample #3
Peak linear acceleration ≤ 208 g
HIC ≤ 1300

Sample #4 and #5
Peak linear acceleration ≤ 208 g
HIC ≤ 1300
Peak rotational acceleration ≤ 10400 rad/s2
BrIC ≤ 0.78

Sample #6
No contact between striker tip and support surface
