Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- - Principle of test: No information related to the method adopted ore the guideline are available.
The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. When several alternate data values appear in the literature, the data is evaluated and representative selections are made; values are then reported with the corresponding source. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem data.
