Each service agency shall have its standards certified at the service agency's expense. Standards shall be tested and certified by either the Department or other metrology laboratories traceable to the National Institute of Standards and Technology (NIST). These laboratories include those in county weights and measures programs, industry, and other states that have been approved, certified, or accredited by NIST, or the Department in accordance with criteria established by NIST, or by other appropriate national or international accrediting organizations. The standards shall be certified as often as the Department deems necessary, based upon a review of supporting statistical data resulting from previous certifications, but in no event shall the period of time between certifications exceed 10 years. In the absence of supporting statistical data, standards shall be certified at least every two years.
