Density

Description of key information

In this weight of evidence approach a study and 5 values from databases/publications/handbooks were taken into account. The study found a range from 1.0620 to 1.0680 g/cm3 for different batches and a mean relative density of 1.0668 g/cm3. All other reported values supported this data.

Key value for chemical safety assessment

Relative density at 20C:

Additional information

In this weight of evidence approach a study and 5 values from databases/publications/handbooks were taken into account. All values were reported to be within the same range as the value found in the study. Therefore the result of the study was supported by literature and the density of 1.0668 g/cm3 at 20 °C found in the study was considered to be valid.

A study was conducted according to OECD TG 109, Regulation (EC) No 440/2008 method A.3, DIN 51757 and ISO 279 to determine the relative density of the test item. Therefore the density was measured at a temperature of 20 °C ± 0.01 °C using an oscillating densitometer. The mean relative density of the test item at 20 °C was determined to be 1.0668 g/cm3. The range of the relative density measurement of the different batches was reported to be from 1.0620 to 1.0680 g/cm3.

In addition the following literature values were available and taken into account: 

The authoritative database from the Institute for Occupational Safety and Health of the German Social Accident Insurance (GESTIS database) was regarded as reliable literature source and was taken into account in this weight of evidence approach. The GESTIS database reported the density of the test item to be 1.066 g/cm3 at 20 °C.

According to the ECHA guidance IR/CSA R7a (May 2008) the CRC handbook was regarded as reliable literature source and was taken into account in this weight of evidence approach. The CRC Handbook of Chemistry and Physics 88th Edition 2007-2008 reported the density to be 1.0622 g/cm3 at 16 °C.

According to the ECHA guidance IR/CSA R7a (May 2008) the REAXYS database contain reviewed and evaluated documents from Handbook of Organic Chemistry as published by Friedrich Beilstein and therefore is regarded as reliable literature source and was taken into account as supporting data. REAXYS database reported the value for density from the publication of Bojko et al. (1968) as 1.0624 g/cm3 at 20 °C.

The Registry database, hosted by the CAS organisation, is regarded as reliable and was therefore taken into account in this weight of evidence approach. The value reported from McElvain (1946) was stated to be 1.0644 g/cm3 at 24 °C.

The handbook “Dangerous Properties of Industrial Materials Report” was regarded as reliable literature source and was taken into account in this weight of evidence approach. The handbook reported the density of the test item to be 1.062 g/cm3 at 20 °C.
