What is SEI / ASTM certification?
SEI is the Safety Equipment Institute, an organization that certifies protective equipment for a variety of industries. ASTM is one of the world’s most respected standards organizations, developing standards for everything from curing of concrete to hotness of red peppers to protective headgear. For equestrian helmets, SEI has selected the ASTM standard F1163 to evaluate helmet performance. All Troxel helmets are SEI / ASTM certified. See our educational resources page for more information. SEI requires testing at an independent lab to the F1163 ASTM standard.
