The hopper scale shall have extended angle irons with hooks 14 inches from edge to hopper, in all four corners, to allow the inspector to hook his chain and binder to 500# weight (or 1000# weight) for testing.  85.63(2)    Method of hopper scale testing.  The method to be used in testing the scale for weighing accuracy shall be by the suspension of standard test weights at each corner of the weighbridge, suspended from a point as near as possible over the center of the main bearing. A suitable permanent device to which the suspension equipment may be connected shall be properly located and placed on each corner of the weighbridge. There is to be no obstruction, such as machinery, spouting or insufficient wall clearance, etc., that will interfere with the free suspension of the weights.  85.63(3)    Approved by department.  Newly installed hopper scales must be approved by the department; this approval shall be based upon blueprints and specifications submitted for this purpose.This rule is intended to implement Iowa Code sections 215.10 and 215.18.Related ARC(s): 7628B, 8292B, 8434B, 0079C, 0953C, 2577C, 4947C
