Montana Title 30. Trade and Commerce § 30-12-205. General testing

(1) When not otherwise provided by law, the department may inspect and test all weights and measures kept, offered, or exposed for sale to determine if they are correct.

(2) The department, within a 12-month period or less frequently if in accordance with a schedule issued by it, and as often as it considers necessary, shall inspect and test, to ascertain if they are correct, all weights and measures commercially used:

(3) With respect to single-service devices designed to be used commercially only once and to be then discarded and with respect to devices uniformly mass-produced, as by means of a mold or die, and not susceptible of individual adjustment, tests may be made on representative samples of the devices. The lots of which the samples are representative must be held to be correct or incorrect upon the basis of the results of the inspections and tests on the samples.

(4) An itinerant peddler or hawker using weights and measures shall register the peddler's or hawker's name and address with the department so that the peddler's or hawker's equipment can be tested in accordance with the provisions of this law.
