Accuracy subject to: On factory approved installations the weigh feeder system's
totalized weight will be within the specified accuracy when compared to a
known weighed material test sample. The test rate must be within the specified
range of the design capacity and held constant for the duration of the test. The
minimum material test sample must be equivalent to a sample obtained at the
test flow rate for three revolutions of the belt or at least ten minutes running
time, whichever is greater.
