適用范圍：1 This part of ISO 7507 specifies a method for the calibration of tanks above 8 m in diameter with cylin-drical courses that are substantially vertical. It pro-vides a method for determining the volumetric quantity contained within a tank at gauged liquid lev-els. The optical (offset) measurements required to deter-mine the circumferences may be taken internally or externally. 2 Abnormally deformed, e.g. dented or non-circular, tanks are excluded from this part of ISO 7507. 3 This method is suitable for tilted tanks up to 3 % deviation from the vertical provided that a cor-rection is applied for the measurement tilt, as de-scribed in ISO 7507-1.
