Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
density, other
Remarks:
packed density
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2014
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods with acceptable restrictions
Qualifier:
no guideline available
Principles of method if other than guideline:
A known amount of the sample was weighted into a graduated cylinder, then with the machine stroke counter the powder was packed.
The packed density was calculated with the following formula:
Packed density (ρ) = weight of the sample (g)/Volume of the sample packed (mL)
GLP compliance:
yes (incl. QA statement)
Type of method:
other: Packed density measured with machine stroke counter
