Description of key information

The density range of Normal-Heptane is 0.687 to 0.693 g/cm3.

Key value for chemical safety assessment

Additional information

The measurement of density or relative density of petroleum distillates by digital density meter is covered by method ASTM D 1298, ISO 12185 or DIN 51757. A range of 0.687 to 0.693 g/cm3 covers all possible grades within this substance description if measured with ASTM D 1298 method. Similar results are obtained by the other methods. Tests conducted by DHC (2010) with a measured value of 0.69 g/cm3 and by Halterman Products (2010) with a measured value of 0.68 confirm this.
