- Executive summary:
A study was performed in accordance with Commission Regulation (EC) No. 440/2008, method A.3 and OECD TG 109 by using the gas comparison pycnometer at 20.0 °C. Two tests were performed and the density of the test item was determined. The relative density of the test item was determined to be D4R 1.41.
Reference
A measurement chamber with a volume of Vc=7.8961 cm3 and an expansion chamber with a volume of Vr=6.0848 cm3 were used. Two test series with different weights were performed at ambient temperature (20.0 °C). For results see Table 1 and Table 2.
