This standard describes the procedures for calibrating upright cylindrical tanks larger than a barrel or drum. It is Tesented in two parts: Part I (Sections to 41) outlines procedures for making necessary measurements to determine total and incremental tank volumes; Part II (Sections 42 to 58) presents the recommended procedure for computing volumes. NOTE 1.-Other calibration standards are: API Standard 2661-ASTM D 1410: Measurement- and Calibration of Horizontal Tanks API Standard 2662-ASTM D 1408: Measurement and Calibration of Spheres and Spheroids API Standard 2663-ASTM D l4?Y: Measurement and Calibratioz of Barges API Standard 2664-ASTM D1409: Measurement and Calibration of Tank Cars API Standard 2666-ASTM D 1406: Liquid Calibration of Tanks
