Minn. R. 7601.4040
For animal and livestock scales, the basic maintenance tolerance is one pound per 1000 pounds of test load (0.1 percent). The acceptance tolerance is one-half of the basic maintenance tolerance.
A shift test must be conducted on animal and livestock scales. The maximum test load is one-fourth of the scale capacity. A scale may be approved if the sum of the indicated errors for two load-bearing readings in the same section is within tolerance.
"Section" means a part of a vehicle, livestock, or railroad track scale that consists of a pair of main load-bearing supports arranged so that the vertical plane passing through both supports is usually transverse to the direction that the load is applied to the scale platform.
