Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
Experimental result performed using standard methods of analysis
Reference:
Composition 0
Qualifier:
according to
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Principles of method if other than guideline:
Determination of the mass at a given temperature of a volume of the material contained in a density bottle (pycnometer) and determination of the volume of the latter by determining the mass of the corresponding volume of water at the same temperature. The density is obtained by dividing the mass of material by its volume.
