Temp.:
20 °C

The value of density : 0.98 g/cm³ is an average of values from 14 different laboratories (OECD-Intercomparison testing program, 1979/80 part I and 1980/81 part II min: 0.9837 and max: 0.9850 g/cm³).

Conclusions:
In the present handbook, the average value of 0.98 g/cm³ at 20 °C is reported.
Executive summary:

In the present handbook, the average value of 0.98 g/cm³ at 20 °C is reported.

This value is extracted from an OECD interlaboratory testing program and was selected in the Risk Assessment Report (final report 2008).

Description of key information

Density: 0.98 g/cm³ at 20°C 1013 mbar. Weight of evidence approach on two data from reference handbooks:

- 0.983 g/cm³, 20°C,(Rippen, 2000);

- 0.9845 g/cm³, 20°C, 1013 hPa, according to DIN 51 757  (BUA, 1986).

- 0,982 g/cm³, 20°C, 1013 hPa, according to OECD 109  (DEZA, 2008)

Key value for chemical safety assessment

Relative density at 20C:
0.98

Additional information

Five data are available to estimate the density of DEHP.

Two data selected for the weight of evidence.

All other data are cited from handbooks or review articles which did not refered to test conditions or procedure. These data are consistent with the value of the weight of evidence and therefore are considered as supportive studies.

- Furtmann, 1996: 0.98 to 0.985 g/cm³

- Staples, 1997: 0.986 (specific gravity)

- Spencer, 2001: 0.98 to 1(specific gravity)
