21—85.1(215) “Sensibility reciprocal” defined. The term “sensibility reciprocal” is defined as to the weight required to move the position of equilibrium of the beam, pan, pointer or other indicating device of a scale, a definite amount.
This rule is intended to implement Iowa Code section 215.18.
21—85.2 to 85.4  Reserved.
21—85.5(215) “Counter scale” defined. A “counter scale” is a scale of any type which is especially adopted on account of its compactness, light weight, moderate capacity and arrangements of parts for use upon a counter, bench, or table.

[ARC 6216C, IAB 2/23/22, effective 5/1/22]
21—85.6(215) “Spring and computing scales” defined. A “spring scale” is a scale in which the weight indications depend upon the change of shape or dimensions of an elastic body or system of such bodies.
	85.6(1) A “computing scale” is a scale which, in addition to indicating the weight, indicates the total price of the amount of commodity weighed for a series of unit prices and must be correct in both its weight and value indications.
	85.6(2) All computing scales shall be equipped with weight indicators and charts on both the dealer’s and customer’s sides.
	85.6(3) Tolerances for both the spring scale and the computing scale shall not be greater than that for counter scales.
This rule is intended to implement Iowa Code section 215.18.
21—85.7(215) “Automatic grain scale” defined. The “automatic grain scale” is one so constructed with a mechanical device that a stream of grain flowing into its hopper can be checked at any given weight, long enough to register said weight and dump the load. The garner above the scale should have at least three times the capacity of the scale to ensure a steady flow at all times.
On automatic-indicating scales. On a particular scale, the maintenance tolerances applied shall be not smaller than one-fourth the value of the minimum reading-face graduation; the acceptance tolerances applied shall be not smaller than one-eighth the value of the minimum reading-face graduation.

All moisture-measuring devices will be tested against a measuring device which will be furnished by the department and all moisture-measuring devices will be inspected to determine whether they are in proper operational condition and supplied with the proper accessories.
This rule is intended to implement Iowa Code section 215A.2.
21—85.53(215A) Rejecting devices. Moisture-measuring devices may be rejected for any of the following reasons:
	85.53(1) The moisture-measuring device tested is found to be out of tolerance with the measuring device used by the department by one of the inspectors so assigned by more than 0.7 percent on grain moisture content.
	85.53(2) The person does not have available the latest charts for type of device being used.
	85.53(3) The person does not have available the proper scale or scales and thermometers for use with the type of device being used.
	85.53(4) The moisture-measuring device is not free from excessive dirt, debris, cracked glass or is not kept in good operational condition at all times.
This rule is intended to implement Iowa Code section 215A.6.
21—85.54(215,215A) Specifications and standards for moisture-measuring devices. The specifications and tolerances for moisture-measuring devices are those established by the United States Department of Agriculture as of November 15, 1971, in chapter XII of GR instruction 916-6, equipment manual, used by the federal grain inspection service; and those recommended by National Bureau of Standards and published in National Bureau of Standards Handbook 44 as of July 1, 1985.
This rule is intended to implement Iowa Code section 215A.3.
21—85.55 and 85.56  Reserved.
21—85.57(215) Testing high-moisture grain. When testing high-moisture grain the operator of a moisture-measuring device shall use the following procedure: Test each sample six times adding the six measurements thus obtained and dividing the total by six to obtain an average which shall be deemed to be the moisture content of such sample.
This rule is intended to implement Iowa Code section 215A.7.
21—85.58 to 85.62  Reserved.
HOPPER SCALES
21—85.63(215) Hopper scales. A “hopper scale” is a scale designed for weighing bulk commodities whose load-receiving element is a tank, box, or hopper mounted on a weighing element; and includes automatic hopper scales, grain hopper scales, and construction material hopper scales.
	85.63(1) Installation. A hopper scale used for commercial purposes shall be so located, or such facilities for normal access thereto shall be so provided that the test weights of the weights and measures official, in the denominations customarily provided, and in the amount deemed necessary by the weights and measures official for the proper testing of the scale, may readily be brought to the scale by customary means; otherwise it shall be the responsibility of the scale owner or operator to supply such special facilities, as required by the weights and measures official. 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.
