Calibration

The pressure readings and the calculated volume for the reference and sample cells are shown in the following table:

Determination	P1 (psig)	P2 (psig)	P3 (psig)	P4 (psig)	Reference cell volume (cm^3)	Sample cell volume (cm^3)
1	14.243	6.530	17.313	8.579	90.856	149.056
2	17.571	6.657	17.230	8.540	90.944	149.100
3	14.925	6.793	17.063	8.458	91.024	149.165

Mean reference cell volume : 90.941 cm³ Mean sample cell volume : 149.107 cm3

As the reference cell volume and sample cell volume were within the defined tolerance (90.953 ± 1.0 cm3 and 149.225 ± 1.0 cm3 for the reference and sample cell volumes respectively) the gas comparison pycnometer was therefore considered acceptable for use.

Sample

The pressure readings, calculated volumes and density values obtained for the test item are shown in the following table:

Determnation	Test	P1(sample) (psig)	P2(sample) (psig)	Volume (cm^3)	Density (kg/cm^3)	Mean Density (kg/m^3)
1	A	18.535	7.906	26.844	1.21 x 10^3	1.21 x 10^3
	B	17.811	7.597	26.839	1.21 x 10^3
	C	17.227	7.343	26.696	1.22 x 10^3
2	A	17.768	7.630	28.273	1.21 x 10^3	1.20 x 10^3
	B	18.607	7.999	28.504	1.20 x 10^3
	C	18028	7.719	28.474	1.20 x 10^3

Mean density : 1.21 x 10³ kg/m³

Relative density : 1.21

Temperature : 20.0 ± 0.5 °C

Duplicate determinations were performed to ensure a reproducibility of less than ± 20 kg/m³ was obtained

Conclusions:

The density of the test item has been determined to be 1.21 x 103 kg/m3 at 20.0 ± 0.5 °C; relative density: 1.21 in a reliable GLP study according to OECD TG 109 using the gas comparison pycnometer method.

Executive summary:

The general physico-chemical properties of Formaldehyde, reaction products with aniline, 4,4'-methylenebis[phenol] have been determined.

Density. 1.21 x 103 kg/m3 at 20.0 ± 0.5 °C, using the a gas comparison pycnometer, designed to be compatible with Method A.3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 109 of the OECD Guidelines for Testing of Chemicals, 02 October 2012. Relative density 1.21.
