TEST ITEM DESCRIPTION AND RESULTS

By Pyknometer Method:

Method Details		Observed Values
		1st Observation	2nd Observation
Guideline	OECD 109
Method	IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision)
Principle of Method	Determination of the mass at a given temperature of a volume of the material contained in a density bottle (pyknometer) and determination of the volume of the latter by determining the mass of the corresponding volume of water at the same temperature. The density is obtained by dividing the mass of material by its volume.
Test temperature	(°C)	20°C	20°C
Atmospheric pressure	(hPa)	978.4	977.6
Weight of empty dry pyknometer(X)	g	29.075	31.048
Weight of pyknometer + test item (Y)	g	82.232	85.252
Apparent mass of test item (M1)	(M1 = Y - X) g	53.157	54.204
Weight of pyknometer + water (Z)	g	78.999	81.550
Apparent mass of water (M2)	(M2 = Z - X) g	49.924	50.502
Buoyancy correction (A)	A = (*ρat × M2)	0.058	0.058
Density of water** at test temperature	g/cm³ (ρtw)	0.9982	0.9982

 

CALCULATIONS:

FOR LIQUIDS

Density = (M1+A)/ (M2+A) X ρtw

1st calculated density	2nd calculated density
(53.157+0.058) ____________ X 0.9982 = 1.062 g/cm3 g/cm³ (48.924+0.058)	(54.204+0.058) ____________ X 0.9982 = 1.071 g/cm3 g/cm³ (50.502+0.058)
Average density	= 1.066 g/cm³

 

Conclusions:

The density of test item was determined following OECD Guideline 109 and according to the IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) using glass pyknometer.The mean density of test chemical was determined to be 1.066 g/cm³ at 20°C and 978 .0 hPa.

Executive summary:

The density of test item was determined following OECD Guideline 109 and according to the IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) using glass pyknometer.The mean density of test chemical was determined to be 1.066 g/cm³ at 20°C and 978 .0 hPa.

Description of key information

Additional information

The density of test item was determined following OECD Guideline 109 and according to the IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) using glass pyknometer.The mean density of test item was determined to be 1.066 g/cm³ at 20°C and 978 .0 hPa.

Other supproting data from reliable sources such as authoritative database and handbooks also suggests that the density of chemical was reported to be in the range of 1.001 g/cm3 to 1.0159 g/cm3 at 20 degree C.

 

As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of density as 1.066 g/cm³ at 20°C and 978 .0 hP,thus considered as key study for the chemical safety assessment
