ISO 12917-2:2002规定了通过使用光电测距仪进行内部测量，校准直径大于2 m的水平圆柱形储罐的方法，以及随后编制储罐容量表的方法。 这种方法被称为内部光电测距（EODR）方法。 ISO 12917-2:2002适用于从水平面倾斜10%的储罐，前提是对测量的倾斜进行校正。

ISO 12917-2:2002 specifies a method for the calibration of horizontal cylindrical tanks having diameters greater than 2 m by means of internal measurements using an electro-optical distance-ranging instrument, and for the subsequent compilation of tank-capacity tables. This method is known as the internal electro-optical distance-ranging (EODR) method. ISO 12917-2:2002 is applicable to tanks inclined by up to 10 % from the horizontal, provided a correction is applied for the measured tilt.
