If a downhill helmet doesn't come with a chin bar, it can be downhill certified based on just the helmet. If the helmet comes with a chin bar (removable or not), there's an extra part in the certification where the chin bar also has to pass certification. If the chin bar doesn't pass certification, you cannot advertise the helmet as a DH certified helmet, even if the helmet without the chin bar passes the helmet certification part.Both the helmet and the chin bar have to pass certification to be sold as a DH certified helmet.
