The calibration of the instrument was verified at 20.0°C with double-distilled water and cyclohexan just before the determinations. The results were:

Water - reference value : 0.998 g/ml - instrument reading : 0.998 g/ml

Cyclohexane - reference value : 0.779 g/ml - instrument reading : 0.778 g/ml

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

The results obtained with Karmalone at 20.0°C were:

first determination : 0.932 g/ml

second determination : 0.932 g/ml

average : 0.932 g/ml

The estimated precision is : +/- 0.001 g/ml

Conclusions:
The density of Karmalone was determined to be 0.932 +/- 0.001 g/ml at 20°C
Executive summary:

The density of Karmalone was determined according to the OECD Guideline No. 109 (oscillating densitimeter method). The result can be expressed as follows:

Density of Karmalone = 0.932 +/- 0.001 g/ml at 20°C

Description of key information

The density of Karmalone was determined according to the OECD Guideline No. 109 (oscillating densitimeter method). The result can be expressed as follows:

Density of Karmalone = 0.932 +/- 0.001 g/ml at 20°C

Key value for chemical safety assessment

Relative density at 20C:
