Tests made by the director of the division of oil and public safety shall be made in accordance with the most recent standard methods of tests of ASTM. The director of the division of oil and public safety is not required in every case to make a complete analysis to ascertain every form of impurities, such as sulphur and tar-like matter, but when, in the opinion of the director, a more complete analysis is necessary or advisable, the director may make a detailed chemical analysis to determine exactly the impurities or imperfections. The director in his or her discretion is authorized to make inspections of petroleum products loaded for shipment into this state, at points outside of this state.
