1 This part of ISO 7507 specifies a method for the calibration of vertical cylindrical tanks having diam-eters greater than 5 m by means of internal measurements using an electro-optical distance-ranging instrument, and for the subsequent compi-lation of tank capacity tables. This method is known as the internal electro-optical distance-ranging (EODR) method.
2 This part of ISO 7507 is not applicable to the calibration of abnormally deformed (e.g. dented) tanks or of noncircular tanks.
3 This part of ISO 7507 is applicable to tanks tilted by ≤ 3 % from the vertical, provided a correction is applied for the measured tilt as described in ISO 7507-1.
4 This part of ISO 7507 is applicable to tanks with cone-up or cone-down bottoms, as well as to tanks with flat bottoms.
