comparison of ECE 22-05 and SNELL M2010

As I mentioned before, DOT, ECE , and SNELL are measured with different approaches. Here, i would like to talk about differences between the ECE 22-05 and SNELL M2010 requirements.

SNELL M2010 requires for instance that any location above the test line is to be tested by two consecutive impacts, while ECE 22-05 requires a single impact only to specific points on the test headform. This makes the total impact energy transferred to each test location by the SNELL M2010 standard, almost twice as high as is the case with the ECE 22-05 tests in some consumer size ranges.

In addition, SNELL M2010 impact absorption tests are carried out with hemispherical and bar anvils. Both anvils are known as harsh to the outer shell performance. Furthermore, to insure the helmet shell is strong enough, shell penetration testing is also required by SNELL M2010, but is missing in the ECE 22-05 standards.
