Delaware Code Title 3. Agriculture § 3133. Inspection and marking of Babcock test bottles

(a) Every person, or agent thereof, engaged in the business of buying milk or cream on the basis of, or in any manner with reference to, the amount of percentage of butterfat contained therein, as determined by the “Babcock test,” shall use standard “Babcock” bottles, pipettes, and weights, as defined in § 3132 of this title. All Babcock test bottles, pipettes, and weights, so used, shall have been inspected for accuracy by the Department of Agriculture, or its proper officer or agent, and shall be legibly and indelibly marked by the Department of Agriculture, or its inspectors of weights and measures, with the letters “S. G. D.” (Standard Glassware Delaware).

(b) No Babcock bottle, pipette, or weight, shall be used for a test unless examined and marked by the inspectors of weights and measures. No person or agent shall use any other than standard test bottles, pipettes and weights, which have been examined and marked as provided in this section, to determine the amount of fat in milk or cream bought on the butterfat basis as determined by the Babcock test.
