Qualifier:
no guideline followed
Principles of method if other than guideline:
The pycnometer was weighed (MP). Then about 30 g (MU) test item was measured into the pycnometer. then about 50 ml water was poured into the it and the suspension was mixed well, and it was placed for 24 hours into a dessicator to remove all bubles from the mixture. Then the pycnometer was filled up with water into the sign and weighed (MT)

The weight of water is MW = MT – Mu - MP
The volume of the water is Vw = MW
The volume of the test item (solid material) is VU = 100 - VW
The density of the test item d (4/20) = MU/VU
GLP compliance:
no
Type of method:
