IP 249: Determination of density - Bingham pyknometer method

Overview:

Scope

This method is intended for the measurement of the density of pure hydrocarbons or petroleum distillates boiling between 90 and 110 °C but can be extended to similar materials outside this boiling range that can be handled in a normal fashion as a liquid at the standard test temperatures of 15 °C, 20 °C and 25 °C. The method was developed especially for the reference fuels n-heptane and isooctane and is designed to provide values having an accuracy of 0,00003 g/ml.

NOTE 1: Other methods for the determination of density or relative density arc listed in the table in Section 1 (Scope) of IP 59.
