Types of Headgear
ASTM International (formerly the American Society for Testing and Materials) set a product performance standard for headgear in soccer in 2006. This standard does not address head to ball contact, solely head to hard surface contact. There are currently two headguards that meet the ASTM soccer headgear standard, the DonJoy Hat Trick and the Full90 Sports Premier-A. Both comply with FIFA, the U.S. Soccer Federation, and the National Federation of State High School Associations (NFHS).

Famous quotes containing the word types:
“Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
—Talcott Parsons (1902–1979)
