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.
Abstract
Overview
ISO 12917-1:2017 - "Petroleum and liquid petroleum products - Calibration of horizontal cylindrical tanks - Part 1: Manual methods" specifies manual procedures for the calibration of nominally horizontal cylindrical tanks installed at fixed locations. The standard covers insulated and non‑insulated tanks, above‑ground or underground, pressurized tanks, and tanks with knuckle‑dish‑end, flat ends, elliptical or spherical heads. Tanks inclined from horizontal are covered provided a tilt correction is applied; practical application limits noted are about 4 m diameter and 10° tilt.
Key topics and requirements
- Scope and applicability: Manual calibration methods for horizontal cylindrical tanks used for petroleum and liquid petroleum products.
- Precautions: Safety and entry procedures follow the general rules in ISO 7507-1; safe‑entry certificates and disconnection/blanking of lines are required for internal work.
- Equipment requirements: Equipment must be traceable to a reference standard (per ISO 7507-1). Specific instruments discussed include:
- Telescopic rod (readable to 1 mm; calibrated with uncertainty
