Qualifier:
according to guideline
Guideline:
EU Method A.3 (Relative Density)
Qualifier:
according to guideline
Guideline:
EPA OPPTS 830.7300 (Density / Relative Density / Bulk Density)
Qualifier:
according to guideline
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Principles of method if other than guideline:
The density and relative density of the test item were determined using a gas comparison stereopycnometer (Pycnomatic, Porotec, Frankfurt, Germany). With this method the volume of the test item is measured in helium gas (Air Products, Amsterdam, The Netherlands) in a calibrated cylinder.
