1.1 Four methods are described to determine the density and relative density of solid and liquid petroleum products and similar materials.
1.1.1 The application of these methods is indicated in the following table:
Product Recommended Method(s) Remarks
A : Relative density Particularly useful when
balance method the quantities avail-
able for test are small
Crude petroleum and B: Graduated bi- Restricted to liquids
liquid products, such capillary pykno- having a Reid vapour
as diesel fuels, gas meter method pressure up to 1.3 kg/
oils, gasolines, kero- cm2 and kinematic
sines, lubricating oih, viscosity up to 50 cS
solvents — naphtha at 15°C
and petroleum C: Capillary stop- Unsuitable for the
pered Pyknometer determination of den-method sity and relative
density of highly volatile liquids
Product Recommended Method(s) Remarks
C: Capillary stop- —
Solid petroleum pro- pered Pyknometer ducts method
D : Displacement —
method
Note — Hydrometer method for the determination of density of crude oil and liquid petroleum products has been prescribed in IS : 1448 [ P : 16 ]-1967*.
