Results of determination of oxidizing properties for the reference mixture (barium nitrate(V) and cellulose) were shown below in Table below.

Ba nitrate (V)(%)	10	20	30	40	50	60	70	80	90
Cellulose (%)	90	80	70	60	50	40	30	20	10
Burning time of the pile (s)	119	114	113	110	112	128	146	303	(25mm/36s)*
Burning rate of the pile (mm/s)	1.68	1.75	1.77	1.82	1.79	1.56	1.37	0.66	0.69
Maximum burning rate of the reference mixture pile (mm/s)	1.82

NI - the train does not ignite,^*the train does not burn completely.

 NI - The train does not ignite.

During the determination, the substance did not burn completely. The train does not ignite regardless the weight ratio of test substance/ cellulose.

Zinc gluconate does not have the oxidizing properties in accordance with test A.17 criteria.

Interpretation of results:

GHS criteria not met

Conclusions:

The test item has been tested according to EU Method A17 (solids).
The reaction time observed during the preliminary screening test shows that the sample is not an oxidising solid.

The test item zinc gluconate does not have oxidizing properties in accordance with test A.17 criteria.

Executive summary:

The test item is considered to not have oxidising properties according to CLP criteria.
