The main differences and improvements introduced by ECE R22-06 compared to its predecessor include:

• Expanded Impact Points Tested: The previous regulation mandated testing on a limited number of helmet shell points. R22-06 significantly extends the number of impact areas tested, including 12 additional randomly selected points, to ensure uniform resistance across the entire helmet surface.

• Impact Tests at Various Speeds: Helmets are now subjected to impact tests at three different speeds (high, medium, and low), providing a more comprehensive evaluation of energy absorption capability in diverse impact scenarios.

• Introduction of Oblique and Rotational Impact Tests: This is one of the most significant innovations. The most severe brain injuries are often related to rotational forces generated by angled impacts. R22-06 introduces specific tests to evaluate the helmet’s ability to manage and dissipate these forces, reducing the risk of complex traumas.

• Assessment of Integrated Accessories: Any accessory integrated into the helmet (such as communication systems, action cameras, or sun visors) must be tested together with the helmet to ensure it does not compromise its performance in the event of an impact or alter its structural integrity.

• Updated Requirements for Visors: More stringent tests have been introduced for the impact resistance and optical properties of visors. For tinted visors, stricter limits for light transmission have been established.

• Approval of Modular (P/J) Helmets: Modular or “crossover” helmets, which allow use in both full-face configuration (chin bar down) and open-face (chin bar up or removed), must now pass specific tests in both configurations (“P” for Protective and “J” for Jet), guaranteeing maximum safety regardless of the mode of use.
