Table #2: Results - Mean values

 Parameter  Value  Standard Deviation
 Volume of Pycnometer  50.04 cm³  0.0001
 Density of Test item  0.9007 g/cm³  0.0048
 Relative Density of Test item  0.9007  0.0048
Conclusions:
The densitiy of the test item Alcohols, C18-22, distn. residues was claculated as 0.9007 ± 0.0001 g/cm³ at 20.0 ± 0.5°C, which is the mean of two values. Precision of the value is given as maximal error of single determination.
The standard deviation of the two values is 0.53% of the mean, the correspondence of the value is good. Therefore, the study is considered valid.
Executive summary:

The study was performed in order to determine the density of Alcohols, C18 -22, distn. residues. The study was conducted in accordance with OECD Guideline No. 109 "Density of Liquids and Solids" dated 27. July 1995 and EU-Method A.3 "Relative Density", dated 31. May 2008.

Using the pycnometer method, a density of 0.9007 ± 0.0001 g/cm³ at 20.0 ± 0.5°C was measured. This value is the mean of two independent determinations with the maximum error of determination. Standard deviation was 0.0048 g/cm³, showing good correlation of the two determinations.

Description of key information

Using the pycnometer method, a density of 0.9007 ± 0.0001 g/cm³ at 20.0 ± 0.5°C was measured.

This value is the mean of two independent determinations with the maximum error of determination.

Standard deviation was 0.0048 g/cm³, showing good correlation of the two determinations.

Key value for chemical safety assessment

Relative density at 20C:
