Introduction
This section GB/T 25685 specifies the performance criteria to monitor and mirror vision mirror mounted on the earth-moving machinery. Depending described
Field is used to define the minimum visible area behind the machine, so that the forward/reverse modes of operation when working around other moving machinery or other
During road transport vehicles for the driver to provide sufficient field of vision.
GB/T 16937 provides that. only when the field of vision can not achieve the performance requirements GB/T 16937 stipulated by the direct field of vision, mirrors can also be
Mounted on the earthmoving machinery to help meet these requirements. Allow to GB/T 25685.1 and GB/T 16937 in the endoscope into the test program
Adjusted in order to achieve GB/T 16937 requirements of this section and GB/T 25685 of.
Mirrors should comply with national regulations, such as. on-road requirements.
