Protective helmets are classified according to the specific impact and electrical performance requirements they are designed to meet. All protective helmets in accordance with this standard shall meet either Type I or Type II impact requirements. In addition, all helmets are further classified as meeting Class G, Class E, or Class C electrical requirements.

Impact Types

• Type I: Helmets intended to reduce the force of impact resulting from a blow only to the top of the head.
• Type II: Helmets intended to reduce the force of impact resulting from a blow which may be received off center or to the top of the head.

Electrical Classes

• Class G (General): Class G helmets are intended to reduce the danger of contact exposure to low voltage conductors. Test samples are prooftested at 2200 volts (phase to ground). However, this voltage is not intended as an indication of the voltage at which the helmet protects the wearer.
• Class E (Electrical): Class E helmets are intended to reduce the danger of exposure to high voltage conductors. Test samples are proof-tested at 20,000 volts (phase to ground). However, this voltage is not intended as an indication of the voltage at which the helmet protects the wearer.
• Class C (Conductive): Class C helmets are not intended to provide protection against contact with electrical conductors.
