relative density
Density:
0.895 other: dimensionless
Temp.:

Accuracy checking:

The calibration of the instrument was verified at 20.0°C with cyclohexane as a reference substance just before the determinations. The results were:

Cyclohexane: reference value: 0.779 g/ml - instrument reading: 0.779 g/ml

The results are within the precision of the instrument (± 0.001 g/ml).

Density determination:

The results obtained with GR-87-7596 at 20.0°C were:

first sample: d = 0.895 g/ml

second sample: d = 0.895 g/ml

average (rounded off): d = 0.895 g/ml or : D(20-4) = 0.895

The estimated precision is: ± 0.001 g/ml.

Conclusions:
density = 0.895 +/- 0.001 g/ml at 20°C
or D 420 = 0.895 +/- 0.001
Executive summary:

The density of GR-87-7596 was determined according to the OECD guideline No. 109 (oscillating densitimeter method). The result can be expressed as follows:

density = 0.895 +/- 0.001 g/ml at 20°C

or D 420 = 0.895 +/- 0.001
