- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- GLP compliance:
- yes
- Type of method:
- pycnometer method

- Temp.:
- 22 °C
- Conclusions:
- The relative density (D4(22)) of HP-1 0 was found to be 1.07
- Executive summary:
A study was performed to determinerelative density of HP-10 was determined relative to purified water using a pyknometer at 22°C.
A saturated solution of the test substance in ethanol:purified water (3: 1 v/v) was employed as the
displacement liquid.
The methods followed were Annex to EEC Directive 92/69/EEC, Method A3 and the OECD Guidelines for the Testing of Chemicals Method 109.
The relative density (D224)of HP-1 0 was found to be 1.07.
