3 Calibration of bottoms of vertical cylindrical tanks
Specifies a method for the calibration of substantially vertical cylindrical tanks by measuring the tank using a strapping tape. Coverage includes precautions, equipment, circumference measurements, recalibration, measurement of tilt, deadwood, tank bottoms, and computation of open capacity. Also gives definitions, tables, diagrams and annexes.
