Scope

This SAE Recommended Practice covers characteristics and dimensions of a critical zone to prevent crushing of an operator during roll-over. It is intended to be used with SAE reports on minimum performance criteria for roll-over protective structure (SAE J320@ J394@ J395@ J396). The critical zone is dimensioned to enclose a large man (95th percentile) in arctic clothing.
