GB/T 16937-2020 Earth-moving machinery—Operator’s field of view—Test method and performance criteria
Basic Information
Scope
This standard specifies the static test methods for determining and evaluating the driver's visibility around the machine's boundary rectangle and the 12-m visibility test circle (VTC). This standard applies to earthmoving machinery defined by ISO 6165, which is used in on-site operations and on roads and has a seated driver's position. This standard specifies the performance criteria for the visibility of various types of machines that meet the maximum working quality of ISO 6165 according to the types of machine families in Table 1. For machines not listed, including large machines, derived earthmoving machinery, and other types of earthmoving machinery, the visibility test procedure can be implemented as a reference and used in conjunction with the risk assessment procedure defined in Section 10.4.
