- Executive summary:
A study was performed in accordance with Commission Regulation (EC) No. 440/2008, method A.3 and OECD 109 by using the gas comparison pycnometer at 22.5 °C. Two tests were performed and the density of the test item was determined. The relative density of the test item at 20 °C (compared with water at 4 °C) was determined to be D4R 1.14.
Reference
Two tests were performed at 22.5 (+/- 0.2) °C.
