EC number: 219-799-4
CAS number: 2536-05-2
Objective and Information
test is conducted to determine the relative density of a solid
or liquid substance.
relative density D204of
solids or liquids is the ratio between the mass of a volume of
substance to be examined, determined at 20°C, and the mass of
the same volume of water, determined at 4°C. The relative
density has no dimension.
a substance is the quotient of the mass, m, and its volume, v.The
density, ρ, is given, in SI units, in kg/m3.
solids or liquids, pycnometers of various shapes and with known
volumes may be employed. The density is calculated from the
difference in weight between the full and empty pycnometer and
its known volume. The tests are run at a constant temperature,
preferably 20°C, and at least two measurements are generally
test is conducted in accordance with the procedure described in
EU Regulation (EC) 440/2008, Annex Part A test A.3 and OECD Test
Mean Result :
Relative density (D204) 1.3426
Test Item density 1342.6 kg.m-3 @ 20°C
A study with 2,2'-MDI reports a relative density of 2,2'-MDI of 1.3426, measured according to EU Method A.3 (air comparison pycnometer (for solids).
