Executive summary:

GUIDELINE

The investigation was conducted in accordance with OECD Guideline 109 Density of Liquids and Solids (October 2, 2012), EC Guideline A.3 Relative Density (March 04, 2016) and EPAProduct Properties Test Guideline OPPTS 830.7300: Density/Relative Density/ Bulk Density (June 2002).

 

RESULTS

The density of the test item was determined by the pycnometer method to be 0.919 g/cm3 (0.919 x 10E03 kg/m3) at 20 °C. Relative density was reported as 0.919.

Description of key information

The density of the test item was determined by the pycnometer method to be 0.919 g/cm3 (0.919 x 10E03 kg/m3) at 20 °C. Relative density was reported as 0.919 (OECD 109, EU Method A.3 and OPPTS 830.7300).
