Petroleum and liquid petroleum products — Calibration of horizontal cylindrical tanks — Part 1: Manual methods

Scope

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, provided a correction is applied for the measured tilt.
Although this document does not impose any limits on the maximum tank diameter and maximum tank tilt to which this document is applicable, the practical limits would be about 4 m in diameter and 10° in tilt.
