Additional information

Key Study: Lammers (2019)

The density of the test material was assessed according to EC Guideline A.3., OECD Guideline 109 and EPA Guideline OPPTS 830.7300 in accordance with the principles of GLP using a gas comparison stereopycnometer. The study was assigned a reliability score of 1 in accordance with the principles for assessing data quality as outlined by Klimisch et al. (1997).

Under the conditions of the test the density of the test material at 20 ºC was 3.37 g/cm3 (3.37 x 10^3 kg/m^3). The relative density was 3.37.

Supporting Information

Information on the density of the read-across substance, sodium periodate, was taken from two peer reviewed handbooks. Sodium periodate is considered to be a suitable substance for read across since it is the sodium salt of periodic acid.

In the CRC handbook, the density of the substance was reported to be 3.86 g/cm³. In the Merck Index, the relative density of the substance was reported to be 3.865 at 16 °C.

The data were assigned a reliability score of 2 according to the principles for assessing data quality outlined in Klimisch et al (1997) and were considered to be suitable as an accurate reflection of the substance.
