scope:
Specifies a method for the calibration of vertical cylindrical tanks having diameters greater than 5 m by means of internal measurements using an electro-optical distance-ranging instrument (EODR), and for the subsequent compilation of tank capacity tables. Not applicable to the calibration of abnormally deformed tanks or of noncircular tanks. Applicable to tanks tilted by ≤ 3 % from the vertical, provided a correction is applied for the measured tilt. Applicable to tanks with cone-up or cone-down bottoms, as well as to tanks with flat bottoms.
