7. Establish labeling standards, establish standards of weight, measure or count and establish reasonable standards of fill for any packaged commodity, and may establish standards for open dating information.

8. Grant, pursuant to this chapter, exemptions from the licensing provisions of this chapter for weighing and measuring instruments, standards or devices when the ownership or use of the instrument or device is limited to federal, state or local government agencies in the performance of official functions. On request, the division may conduct inspections of instruments, standards or devices and shall charge a fee pursuant to section 3-3452.

9. Delegate to appropriate personnel any of the responsibilities of the associate director for the proper administration of this chapter.

10. Inspect and test weights and measures that are kept, offered or exposed for sale.

11. Inspect and test, to ascertain if they are correct, weights and measures that are commercially used either:

(a) In determining the weight, measure or count of commodities or things sold, or offered or exposed for sale, on the basis of weight, measure or count.

(b) In computing the basic charge or payment for services rendered on the basis of weight, measure or count.

12. Test, at random, commodities, weights and measures that are used in public institutions for which monies are appropriated by the legislature. The testing of commodities, weights and measures in public institutions includes items:

The division may affix a nontampering seal to commercial devices that are tested and found to be within applicable tolerance.

14. Sample and test motor fuel that is stored, sold or exposed or offered for sale or that is stored for use by a fleet owner to determine whether the motor fuel meets the standards for motor fuel set forth in section 3-3433 and article 6 of this chapter and in any rule adopted by the associate director pursuant to this chapter.

15. Randomly witness tests on all mandated vapor recovery systems that are installed or operated in this state and, if the systems are determined to be in compliance with the law, approve those systems for use and reject, mark as rejected and stop the use of those systems that are determined not to be in compliance with the law.

19. Allow reasonable variations from the stated quantity of contents only after a commodity has entered intrastate commerce. These variations shall include those caused by loss or gain of moisture during the course of good distribution practice or by unavoidable deviations in good manufacturing practice.

20. Prescribe the standards of weight and measure and additional equipment methods of test and inspection to be employed in the enforcement of this chapter. The associate director may prescribe or provide the official test and inspection forms to be used in the enforcement of this chapter.

The associate director of the division shall consult with the director of the department of environmental quality in adopting rules pursuant to this subsection.

E. Testing and inspection conducted pursuant to this chapter shall be done, to the extent practicable, without prior notice, by a random systematic method determined by the associate director or in response to a complaint by the public.
