Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- bulk density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- other:
- Version / remarks:
- ASTM B212-17
- Principles of method if other than guideline:
- Using a graduated plastic cylinder, the powder was poured into the cylinder to fill up to top of the graduated line. The initial volume and weight of the material measured. The pour density then calculated as weight of sample/volume measured from the graduated cylinder. The powder inside the graduated cylinder is then tap in a consistent force 100X. The volume displacement was then measured. The tap density then calculated as weight of sample/volume measured from the graduated cylinder.
- GLP compliance:
- no
- Type of method:
- pour and tap (for solids)
- Specific details on test material used for the study:
- Zinc diacrylate (SR111); CAS No. 14643-87-9; Lot No. 705 SC1703131C & 705 SC170103AC; Purity 100 %

- Type:
- density
- Density:
- 1.687 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- Under the test conditions, the relative density of the test substance was determined to be 1.68 g/cm3. This result was confirmed in a 2nd independent run with test substance of a different Lot.
- Executive summary:
A study was conducted to determine the bulk and relative density of the test substance in analogy to Method ASTM B212 -17. Under the test conditions, the bulk density was determined to be 0.33 g/ml and the relative density 1.68 g/cm3 (Wylin, 2017).
