Key result

Type:

relative density

Density:

998.9 kg/m³

Temp.:

20 °C

Remarks on result:

other: final result (mean value of three independent determinations) - relative density at 20°C in reference with water at 4°C.

The results are presented in the following table. 

Assay No.	Density (kg/m^3)	Relative density
1	998.7	0.9987
2	999.0	0.9990
3	999.1	0.9991

Relative density = density (kg/m³) / 999.975 (kg/mm³) (density of water at 4°C).

The average density at 20°C ± 0.5 °C of the test item is 998.9 kg/m³.

Conclusions:

The relative density at 20°C of REACTION PRODUCTS OF 2,2-BIS(HYDROXYMETHYL)-1,3-PROPANEDIOL AND 3,9-DIVINYL-2,4,8,10-TETRAOXASPIRO[5.5]UNDECANE AND TRIMETHOXYMETHANE was determined to be 0.9989.

Executive summary:

The purpose of the study was to determine the relative density of substance REACTION PRODUCTS OF 2,2-BIS(HYDROXYMETHYL)-1,3-PROPANEDIOL AND 3,9-DIVINYL-2,4,8,10-TETRAOXASPIRO[5.5]UNDECANE AND TRIMETHOXYMETHANE.

The determination of the relative density was performed in accordance with Regulation (EC) No 440/2008, method A.3 ''Relative density'' and OECD Guideline No 109 ''Density of liquids and solids'' (July 1995). The oscillating density meter method was used.

Three measurements were performed at 20°C ± 0.5°C.

The relative density 20°C/4°C of REACTION PRODUCTS OF 2,2-BIS(HYDROXYMETHYL)-1,3-PROPANEDIOL AND 3,9-DIVINYL-2,4,8,10-TETRAOXASPIRO[5.5]UNDECANE AND TRIMETHOXYMETHANE was determined to be 0.9989.
