EC number: 252-068-8
CAS number: 34513-98-9
The test substance was
compatible with the CORROSITEX™ test system. As the sample was intensely
coloured, any colour-change reaction in the categorisation tubes was
indistinct. Based on pH measurement the test substance was assigned to
Positive and negative
control test substances:
The reaction times of
positive controls nitric acid and phosphoric acid were 1.97 and 16.42
minutes, respectively. The reaction time of the negative control was
67.67 minutes. The acceptance criteria for the control substances were
The mean time of the test
substance to activate the CDS was 12.83 minutes.
a good quality GLP study, conducted according to OECD test guideline
435, the potential of tris(nitrato-O)nitrosyl ruthenium(II) (solid) to
induce skin corrosion was assessed in the "in vitro membrane barrier
test (CORROSITEX™ Assay)".
test item was placed on top of a BIOBARRIER membrane which was sat on a
chemical detection system (CDS) in a vial. Corrosivity is determined on
the ability (measured by the time taken) of a chemical to break through
the barrier and subsequently activate the underlying CDS (as seen by a
colour or consistency change).
mean time required for tris(nitrato-O)nitrosyl ruthenium(II) (solid) to
activate the CDS was 12.83 minutes (mean of 4 replicates). The test
substance is therefore classified as "corrosive" sub category 1B,
according to UN GHS criteria, as the mean time to activate the CDS was
between 3 -60 minutes (category 1).
