- Endpoint:
- density, other
- Remarks:
- density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Deviations:
- no
- Remarks:
- The guideline is not stated in the report, but the study follows the principles of OECD 109 guideline.
- Principles of method if other than guideline:
- The density of zinc silicate was determined using a helium pentapycnometer.
- GLP compliance:
- no
- Other quality assurance:
- other: analytical lab is certified under ISO 9001:2008

- Key result
- Type:
- density
- Density:
- 4.3 g/cm³
- Temp.:
- 22 °C
- Conclusions:
- The density of zinc silicate was determined to be 4.3 g/cm3.
- Executive summary:
The density of the test item was determined using a helium pentapycnometer. The guideline is not stated in the report, but the study was performed according a standard method equivalent to the OECD 109 guideline.
This is a non-GLP experimental study and there are minor restrictions in reporting but it is otherwise acceptable as the key study for this endpoint.
The density of zinc silicate is 4.3 g/cm3.
