		Mean burning time: 136 s
Results of 4:1 (by mass) test item and cellulose mixture
Test Number	Burning Time (s)	Observations
1	-	Pale grey smoke, no sign of ignition during the 3 minutes the power was applied
2	-	Dark grey smoke, no sign of ignition during the 3 minutes the power was applied
3	-	Dark grey smoke, no sign of ignition during the 3 minutes the power was applied
4	-	Dark grey smoke, no sign of ignition during the 3 minutes the power was applied
5	-	Dark grey smoke, no sign of ignition during the 3 minutes the power was applied
Results of 1:1 (by mass) test item and cellulose mixture
1	-	Pale grey smoke, the pile was slightly charred
2	-	Pale grey smoke, the pile was slightly charred
3	-	Pale grey smoke, the pile was slightly charred
4	-	Pale grey smoke, the pile was slightly charred
5	-	Pale grey smoke, the pile was slightly charred

The 4:1 and 1:1 test item:cellulose mixtures did not ignite and burn during the 3 minutes that the power was applied. This indicates that the test item is not an oxidising solid.

Interpretation of results:

GHS criteria not met

Conclusions:

Tetraammonium decachloro-mu-oxodiruthenate (4-) is not classified as an oxidising solid in accordance with Regulation (EC) No 1272/2008 of 16 December 2008 on Classification, Labelling and Packaging of Substances and Mixtures.

Executive summary:

Tremain and Atwal (2011) is a GLP compliant study following UN method O1 and is considered suitable for use as they key study for this endpoint. Tetraammonium decachloro-mu-oxodiruthenate (4-) is not classified as an oxidising solid in accordance with Regulation (EC) No 1272/2008 of 16 December 2008 on Classification, Labelling and Packaging of Substances and Mixtures.

Description of key information

Tetraammonium decachloro-mu-oxodiruthenate (4-) is not classified as an oxidising solid in accordance with CLP regulations.

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Additional information

Tremain and Atwal (2011) is a GLP compliant study following UN method O.1 and is considered suitable for use as they key study for this endpoint. Tetraammonium decachloro-mu-oxodiruthenate (4-) is not classified as an oxidising solid in accordance with Regulation (EC) No 1272/2008 of 16 December 2008 on Classification, Labelling and Packaging of Substances and Mixtures.

Justification for classification or non-classification

Based on the result of a GLP compliant study following UN method O.1, tetraammonium decachloro-mu-oxodiruthenate (4-) is not classified as a oxidising solids in accordance with CLP regulations.
