scope:

This standard applies to rough-terrain variable reach trucks (herein-after referred to as "trucks") as defined in 3.1.2 that have a specific seated operator's position, on the left hand side of the boom, or centre position (excluding operator position on the right side of the boom). This 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 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 and for travelling on public roads.
