Scope
This document specifies the static and dynamic strength test procedures for the rear-mounted rollover protection devices of narrow-track wheeled tractors used in agriculture and forestry. It defines the safe area and sets out the acceptance criteria for the cab, rear-mounted fixed or foldable double-column and frame-type rollover protection devices. It also prescribes optional test procedures for seat belt anchorage devices and foldable rear-mounted rollover protection devices.
