Michigan Compiled Laws, Chapter 290. Weights, Measures and Standards § 290.608

Sec. 8. (1) The director may promulgate rules necessary to administer and enforce this act. These rules may include any of the following:

(2) The director shall promulgate rules that provide for specifications, tolerances, and regulations for weights and measures specified in section 10 that are designed to eliminate from use, without prejudice to apparatuses that conform as closely as practicable to the official standards, those apparatuses that are not accurate, that are of such construction so as not to be reasonably permanent in their adjustment or will not repeat their indications correctly, or that facilitate the perpetration of fraud. The specifications, tolerances, and regulations for commercial weights and measures, together with amendments to those specifications, tolerances, and regulations, as described in section 28c, shall be the specifications and tolerances for commercial weights and measures of this state except as specifically supplemented, updated, modified, amended, or rejected by a rule of the director. For the purposes of this act, an apparatus shall be considered to be correct when it conforms to all applicable rules adopted as specified in this section. An apparatus is considered to be incorrect if it does not conform to all applicable standards incorporated by reference in section 28c and rules adopted under this section.

(3) The director may grant exemptions to the specifications published in the standards, incorporated by reference in section 28c, if a written request for an exemption is submitted stating the reason an exemption is required or desirable. The term of any granted exemption shall be set by the director with the exemption subject to revocation if the terms of the exemption agreement are not met.
