Basic Information
Scope
This document specifies a static test method for determining and evaluating the operator's field of vision within a rectangular boundary and a 12-m viewing circle around an off-road articulated telescopic forklift (hereinafter referred to as "forklift"). This document also specifies the performance requirements for the field of vision. Calculation methods or computer simulations may also be used. This document applies to off-road articulated telescopic forklifts defined in ISO 5053-1:2020, section 3.22, where the operator's position is located on the left or center side of the boom (excluding those with the operator's position on the right side of the boom). This document does not provide performance requirements for other methods of indirect vision. This document also includes information that must be provided by the manufacturer.
