1. Hierarchy of accuracies
2. Isothermal compressibility factor for water
3. Throughput calculations and corresponding meter
     factor calculations
4. Temperature correction factors for steel - Cts for
     mild steel having a cubical coefficient of
     expansion of 3.3 x 10 (to the power -5) / deg C
5. Temperature correction factors for steel - Cts for
     stainless steel having a cubical coefficient of
     expansion of 5.1 x 10 (to the power -5) / deg C
6. Correction factors for effect of pressure on a
     mild steel prover
7. Correction factors for effect of pressure on a
     mild steel prover

Describes the various terms employed in the calculation of metered petroleum quantities. Also specifies equations which allow values of correction factors to be computed and gives rules for the sequence, rounding and significant figures to be employed in a calculation. Provides tables to look up to specific correction factors should it not be desired to calculate them. The calculation of prover base volumes, meter factors and measurement tickets are also covered. The field of application of this standard is the volumetric measurement of liquid hydrocarbons. Does not include two-phase fluids except in so far as sediment and water may be mixed in with crude oil.
