This document refers to temperature volume correction factors, which allow users to convert volumes,
measured at ambient conditions, to those at reference conditions for transactional purposes. This
document also refers to compressibility factors required to correct hydrocarbon volumes measured
under pressure to the corresponding volumes at the equilibrium pressure for the measured
temperature.
Table 1 shows the defining limits and their associated units of correction factors referenced in ...

ISO 12917-1:2017 specifies manual methods for the calibration of nominally horizontal cylindrical tanks, installed at fixed locations. The methods in this document are applicable to insulated and non-insulated tanks, either when they are above-ground or underground. The methods are applicable to pressurized tanks and to both knuckle-dish-end and flat-end cylindrical tanks as well as elliptical and spherical head tanks. ISO 12917-1:2017 is applicable to tanks inclined from the horizontal, provide...view more

This part of ISO 7507 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. The method 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. This part of ISO 7507 also applies ...view more

ISO 7507-3:2006 specifies a calibration procedure for application to tanks above 8 m in diameter with cylindrical courses that are substantially vertical. It provides a method for determining the volumetric quantity contained within a tank at gauged liquid levels. The measurements required to determine the radius are made either internally or externally. The external method is applicable only to tanks that are free of insulation.

Specifies a method for the calibration of non-insulated vertical cylindrical tanks having diameters greater than 5 m by means of external measurement using an electro-optical distance-ranging method (EODR), and for the subsequent compilation of tank capacity tables. This part is applicable to tanks with cone-up or cone-down bottoms as well as to tanks with flat bottoms.

Specifies a method for the calibration of tanks by addition of batches of liquid. The liquid is used as a volume-transfer medium, measured accurately by means of a meter. This  International Standard is not  applicable to the calibration of  reference measuring instruments, proving tanks, or meter provers. NOTE Applicable standards are given in the  bibliography.

This part of ISO 7507 specifies a method for the calibration of substantially vertical cylindrical tanks by measuring the tank using a strapping tape. This method is known as the strapping method and is suitable for use as a working method, a reference method or a referee method. The operation of strapping, the corrections to be made and the calculations leading to the compilation of the tank capacity table are described. This method does not apply to abnormally deformed, e.g. dented or non-circ...view more

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.
