Description of key information
test waived: inorganic substance, absence of structural alerts (expert judgement, based on IUCLID 4.23: chemical and mineralogical composition of a representative UVCB)
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
UVCB is inorganic, solid, and a complex metal containing substance.
The studied three (3) representative cupro samples contain 24.7- 68% copper, 5.8- 12.4% nickel, 0.8- 18.7% lead, 2.1- 8.9% iron, 2.2- 4.1% tin and 12.3- 17.1% silicon and consist mainly of copper-, iron- and nickelsilicides.
Mineralogical composition of sample 09TT02932 (=metallic fraction) is 52.1% coppersilicide, 17.7% ferrisilicide, 11.9% copper aluminium alloys and 11.2% nickelsilicide with accessory nickel alloys, metallic tin and lead, while sample 09TT02933 (= corresponding oxidic fraction) consist 24.6% ferrisilicide, 20.5% nickel silicide, 18.4% lead, 10.9% copper tin alloys and 10% metallic copper. Sample 09TT05024 (=metallic fraction of Al-loaded material) consist 49.5% coppersilicide, 26.7% copper aluminium alloys, 15.6% nickelsilicide with accessory copper tin alloys, ferrisilicide and metallic lead.
These mineralogical data confirms that substance do not contain constituents that could act as oxidising agent (eg metal oxide content is very low, dominating are silicides).
Justification for classification or non-classification
The evaluation from the expert is confirmed by experience in handling and use: the substance is known to be sensitive to air and this already suggests it will not act as oxidiser itself.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
