标准摘要
[中文适用范围]： ISO 7507的本部分规定了通过使用电光测距（EODR）仪器进行内部测量来校准直径大于5 m的立式圆柱形储罐的方法，以及随后编制储罐容量表的方法。 该方法适用于与垂直方向偏差达 3% 的储罐，前提是按照 ISO 7507-1:2003 第 11 条的规定对测量的倾斜进行修正。 ISO 7507 的这一部分也适用于浮动屋顶或内部浮动毯。 [外文原描述]： ISO 7507-4:2010 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 (EODR) instrument, and for the subsequent compilation of tank capacity tables. ISO 7507-4:2010 is suitable for tanks tilted up to a 3 % deviation from the vertical, provided that a correction is applied for the measured tilt as described in ISO 7507-1:2003, Clause 11. ISO 7507-4:2010 also applies to tanks with floating roofs or internal floating blankets.
