This European Standard specifies a static test method for determining and evaluating the operator"s visibility on a rectangular 1 m boundary close around the rough-terrain variable reach truck and on a 12 m visibility test circle.

This European Standard does not apply to rough-terrain variable reach trucks designed to handle freight containers (rough-terrain reach stackers). It applies to trucks for operation on work sites.
