The Secretary shall issue from time to time reasonable regulations for the enforcement of this chapter, which regulations shall have the force and effect of law. These regulations may include (1) standards of net weight, measure, or count, and reasonable standards of fill, for any commodity in package form, (2) rules governing the technical and reporting procedures to be followed and the report and record forms and marks of approval and rejection to be used by inspectors of weights and measures in the discharge of their official duties, (3) exemptions from the sealing or marking requirements of § 5113 of this chapter with respect to weights and measures of such character or size that such sealing or marking would be inappropriate, impracticable or damaging to the apparatus in question, and (4) rules governing the voluntary registration of service people and service agencies. These regulations shall include specifications, tolerances and other technical requirements for weights and measures of the character of those specified in § 5109 of this chapter, designed to eliminate from use, without prejudice to apparatus that conforms as closely as practicable to the official standards, those (1) that are not accurate, (2) that are of such construction that they are faulty — that is, that are not reasonably permanent in their adjustment or will not repeat their indications correctly — or (3) that facilitate the perpetration of fraud. The specifications, tolerances and other technical requirements for commercial weighing and measuring devices, together with amendments thereto, as recommended by the National Bureau of Standards and published in the National Bureau of Standards Handbook 44 and supplements thereto, or in any publication revising or superseding Handbook 44, shall be the specifications, tolerances and other technical requirements for commercial weighing and measuring devices of the State, except insofar as specifically modified, amended or rejected by a regulation issued by the Secretary. For the purposes of this chapter, apparatus shall be deemed to be “correct,” when it conforms to the requirements of the National Type Evaluation Program of the National Institute of Standards and Technology. A certificate of conformance must be issued prior to the use of such weight(s) and measure(s) or weighing and measuring device for commercial or law-enforcement purposes, except insofar as specifically modified, amended, or rejected by a regulation issued by the Secretary of Agriculture. Pending the issuance of a certificate of conformance, the Department may permit such weight(s) and measure(s) or weighing and measuring device to be used provided it meets the specifications and tolerances for that particular weight and measure or weighing device as set forth in the National Institute of Standards and Technology Handbook 44.
