Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- other: handbook
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Remarks:
- Handbook data are considered from a trusted source. Data have been taken from many sources, including both compilations and the primary literature - where conflicts were found, the value deemed most reliable was chosen. The reference was peer-reviewed. In addition, the reference sources are indicated although not leading to sufficient information on the material & method used.
- Guideline:
- other: not mentioned
- Principles of method if other than guideline:
- Method followed unknown; data from handbook.
- GLP compliance:
- not specified
- Type:
- relative density
- Density:
- 2.26 g/cm³
- Remarks on result:
- other: Near room temperature
- Conclusions:
- The CRC Handbook of Chemistry and Physics (80th ed.) mentions a density near room temperature of 2.26 g/cm3 for sodium nitrate.

- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- documentation insufficient for assessment
- Remarks:
- The preface and introduction to this book (9th Edition) provide no indication that the physico-chemical data has been ‘peer reviewed’. The reference source is not indicated leading to insufficient information on the material & method used.
