Short Helmet Standards Comparison

This chart comes from our Short Standards comparison. We also have a longer and much more detailed point by point helmet standards comparison.

*Snell B-95 uses a more severe impact for initial certification than for follow-up performance testing,
2.2 for flat anvil and 1.5m for hemi and curbstone.

**adult test on medium headform, flat anvil. Certification
for Snell B95 is 110 J.

***Snell considers the B-95 strap jerk test to be roughly equivalent to the B-90A test, although parameters have changed.
