The ASTM F2040 standard is the definitive benchmark for ski helmet safety in North America, and my team at SPIRIT has spent years mastering its rigorous demands. It is a highly specific standard, designed to replicate the real-world forces a skier or snowboarder might encounter. It involves a battery of impact tests in controlled, cold-temperature environments, where the helmet is dropped onto various anvil shapes to test its ability to absorb energy. The standard also includes tests for the strength of the retention system and the helmet's stability on the head. Our in-house testing laboratory is fully equipped to test to every protocol within the ASTM F2040 standard. This allows us to test and refine our prototypes relentlessly, ensuring that by the time we send a new ski helmet for official third-party certification, we are absolutely confident it will pass. This mastery provides our OEM partners with a crucial guarantee of compliance and safety.
