TEST DESCRIPTION AND RESULTS

Method Details		Observations	Remarks if, any
Guideline	OECD 109	-
Method	Pycnometer method	-
Principle of method	The density is calculated from the difference in weight between the full and empty pycnometer and its volume.	-
Test temperature (°C)	-	20°C
Atmospheric pressure (in hPa)	-	967.5 hPa
Weight of dry pycnometer (g)	(W1)	29.641 gm
Weight of pycnometer + water (g)	(W2)	78.853 gm
Weight of pycnometer + test substance (g)	(W3)	80.986 gm
Density of water at test temperature (g/cm^3)	(ρH2O)	0.9982 g/cm3

 

CALCULATIONS:

Parameters	Details	Calculated Values
Weight of water	(mH2O)=W2 -  W1	49.212 gm
Weight of test substance	(mL)= W3 – W1	51.345 gm
Density of test substance(RESULT)	ρL      = mL xρH2O               mH2O	1.0414 g/cm^3

Conclusions:

The mean density of test chemical was determined to be 1.0414 g/cm³ at 20°C and 967.5 hPa.

Executive summary:

The density of test chemical was determined following OECD Guideline 109 using pyknometer. The mean density of test chemical was determined to be 1.0414 g/cm³ at 20°C and 967.5 hPa.
