Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
The substance is a wet solid or a sludge. A bench scale filter press was used to determine the cake density of the substance. Membrane filtrations was utilized to squeeze pure water from the cake. The chamber had a filtration volume before squeezing of 115cm3. The mass of the filter cake was recorded on a Mettler Toledo PB3002-S/FACT balance, with 0,01 g precision.
GLP compliance:
no
Type of method:
other: in-house method

Applicant's summary and conclusion

Conclusions:
The bulk density was determined to be 1.4 kg/dm3.
Executive summary:

The bulk density of the UVCB substance Zinc Copper Sulphate was determined after filtration in a filter press to 1,4 kg/dm3 with a moisture content of ca. 65wt%. The density will change with changes is dryness due to ageing, packing etc. the density is reported for a representative sample of the newlt produced UVCB substance.
