Qualifier:

according to guideline

Guideline:

OECD Guideline 109 (Density of Liquids and Solids)

Deviations:

no

GLP compliance:

Type of method:

oscillating densitimeter

Type:

relative density

Density:

0.965 other: g/mL

Temp.:

20 °C

Density at 20 °C:
1. Determination 0.9646 g/mL
2. Determination 0.9646 g/mL
Relative Density D420: 0.965 (mean value)

Conclusions:

The relative density D420 at 20 °C of the test item was determined as 0.965 (mean value).

Executive summary:

The relative density of the test substance was determined using an oscillating densitometer according to OECD TG 109.

The liquid sample was introduced into an oscillating tube of the densitometer instrument. The change in the oscillating frequency due to the change in mass of the tube was used to determine the density of the sample. The instrument was calibrated with water and checked with a standard oil (LIMS ID 4289).

The relative density D420 at 20 °C of the test item was determined as 0.965 (mean value).
