Table 1: Density determination
Mass of pycnometer (empty) [g]
Mass of pycnometer + test item [g]
Mass of test item [g]1)
Volume of pycnometer [cm2]2)
Mean value of density [g/cm3]
1) calculated from the masses
2) known from calibration
3) calculated from the mass of the test item and volume of the pycnometer
The relative density D420 is: 1.3417 g/cm3:
0.99997 g/cm3 = 1.3417
(0.99997 g/cm3as density of water at 4°C)
Relative density: 1.3417 at 20°C (OECD 109)
A measured relative density value of 1.3417 at 20°C was determined for
the registration substance using pycnometer method in accordance with
OECD Test Guideline 109 and in compliance with GLP. The result is
considered to be reliable and selected as key study.
In a secondary source to which reliability could not be assigned, a
density value of 1.334 g/cm3 at 20°C was reported for the
