Temp.:

20 °C

METHOD

The density at 20 ⁰C of test item was measured using a Mettler DE40 oscillating tube densitometer. Testing was conducted using Method A3 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC). Density was converted to the relative density compared to water at 4 ⁰C.

PROCEDURE

The instrument was first qualified by measuring the density of the Cannon standard reference oil N4 at 20 ⁰C. The measured density was 0.7914 g/mL versus the standard reference value of 0.7913 g/mL.

After running the standard reference material, the cell was cleaned and dried and approximately 3 mL of liquid test item was injected into the sample analysis tube. When the sample equilibrated to the set temperature, an audible signal indicated that the density value could be read from the instrument. The measurement was repeated with a fresh sample.

Conclusions:

The density at 20 ⁰C was determined to be 0.8569 +/- 0.0001 g/ml, which converts to a relative density of 0.8569 +/- 0.0001.

Executive summary:

The relative density study was performed according to EU method A.3 (oscillating tube densitometer). The density at 20 °C was determined to be 0.8569 +/- 0.0001 g/ml, which converts to a relative density of 0.8569 +/- 0.0001.

Description of key information
