Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- according to guideline
- Guideline:
- other: ISO 3944:1992 modified; PN-EN 1236:1999
- Principles of method if other than guideline:
- Procedure: ISO 3944:1992 modified; PN-EN 1236:1999
The sample of DTPA-MnNa3 is poured into the measuring cylinder with known volume (with accuracy 1 cm3), using the funnel.
The funnel should be closed during dosing the sample; then the bolt closing the funnel is removed. The sample should fill the cylinder during 6 to 12 s.
After filling in the cylinder over the above edge, the excess of the sample is removed by spatula, avoiding shaking of the cylinder.
The cylinder is weighting on the scale with the precision of measurement 1 g.
Two measurements are conducted for two portions of the sample from one batch part.
Calculation: Bulk density (loose) of the sample, ρ, measured in kg/m3 is calculated from the formula:
ρ = m/V,
where:
m – the weight of the sample into cylinder, expressed in kg,
V – volume of the cylinder to the above edge, expressed in m3 - GLP compliance:
- no
- Type of method:
- pour and tap (for solids)
- Type:
- bulk density
- Density:
- 850 kg/m³
- Temp.:
- 20 °C
- Conclusions:
- Bulk density (loose): 850 ± 100 kg/m3
- Executive summary:
The bulk density (loose) for target substance DTPA-MnNa3 was established acc. method ISO 3944:1992 modified; PN-EN 1236:1999.
Two measurements are conducted for two portions of the sample from one batch part.The bulk density (loose) is 850 +/- 100 kg/m3.
