ECE standards test for safety features that can contribute to avoiding an accident altogether, such as the optical quality of approved face shields and safety factors not directly related to impact, such as shell rigidity. Unlike the DOT, every ECE 22.05 certified helmet model must actually be tested against the standard by an independent lab before it is available for sale with an ECE sticker. standards
