- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- Regulation EC No. 440/2008 Part A., Method A.3. Relative Density
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7300 (Density / Relative Density / Bulk Density)
- Version / remarks:
- EPA OCSPP Test Guideline 830.7300 (2002) Density/Relative Density/Bulk Density

- Key result
- Type:
- density
- Density:
- 1.46 g/cm³
- Temp.:
- 20 °C
- Key result
- Type:
- relative density
- Density:
- 1.46 other: no unit
- Temp.:
- 20 °C
- Conclusions:
- relative density (at 20 °C ±0.01 °C): 1.46
- Executive summary:
The density was determined in a GLP guideline study according to OECD 109 and EU method A.3 using a calibrated gas comparison pycnometer.
The relative density D420of the test item Tris(hydroxymethyl)phosphine oxide (THPO) at 20 °C ± 0.01 °C (compared to water at 4 °C) is D420 = 1.46.

Description of key information
relative density (determined using EU Method A.3 / OECD 109; GLP): 1.46 at 20 ±0.1 °C (arithmetic mean of two determinations)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.46
Additional information
The relative density of the test material was investigated using a gas comparison pycnometer, designed to be compatible with EU Method A.3 and OECD 109. A reliability score of 1 was assigned, in accordance with the criteria for assigning data quality in line with the principles described by Klimisch (1997).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
