How often does NOCSAE recommend reconditioning and recertifying used helmets?

NOCSAE, which stands for the National Operating Committee on Standards for Athletic Equipment, recommends that used helmets be reconditioned and recertified every two years. This guideline ensures that helmets continue to provide the necessary protection to athletes by verifying that they are free of defects and can still absorb impacts effectively. The two-year timeframe accounts for the accumulation of wear and tear that helmets endure during use, as well as ensuring that any technological advancements in helmet safety standards are taken into consideration. Regular maintenance through reconditioning helps to maintain the integrity of the helmet and the safety of the athlete, enabling them to participate in sports with an appropriate level of protection.
