Guideline:
other: QC-AM- 0001
Version / remarks:
Internal analytical method to determine the relative density
Deviations:
no
Principles of method if other than guideline:
Anton PAAR Oscillating U-tube method: a hollow U-shaped tube is electromagnetically forced into harmonic oscillation. The period of oscillation is dependent on the density of the sample in the tube. Therefore, by measuring the period of oscillation, the density or density related values are automatically calculated.
GLP compliance:

Type:
relative density
Density:
0.87 other: relative to water at 4 °C
Temp.:
20 °C
Remarks on result:
other: The result is the average of 33 results. Each result was generated with a different batch.
Conclusions:
The average relative density of the test item was found to be 0.8695.
Executive summary:

The relative density is determined in-house using a digital densitometer that operates according to the the Anton PAAR oscillating U-tube method. The average relative density of the test item was found to be 0.8695. The result is the average of 33 results on different batches.

Description of key information

A weight of evidence approach has been taken for this endpoint. There are 2 results available for relative density from renowned handbooks: 0.870 g/ml (CRC Handbook, 1993) and 0.8692 (Merck Index, 2001). Additionally, company data are available. In total 33 relative density measurements were performed on 33 different product batches. The mean relative density was found to be 0.8695.

Key value for chemical safety assessment

Relative density at 20C:
0.87
