Preliminary test

In contact with the ignition source the sample showed a local burning. A propagation of burning was not ascertained. After removing of the ignition source rapid extinction of reaction was observed.

Main test

The following results were obtained:

Reference mixtures (barium nitrate/cellulose)       Highest value of burning rate [mm/s]

50 : 50                                                           2.78

60 : 40                                                          2.86

70 : 30                                                          2.25

55 : 45                                                          3.23

The reference mixture 55 % barium nitrate : 45 % cellulose has a maximum burning rate of 3.23 mm/s. This is the highest burning rate of all single tests. (The required tolerance range of 10 % around the mean value of six single tests was achieved.)

Test substance mixtures       Highest value of burning rate

Test item /Cellulose              [mm/s]

10 : 90                                 2.99 (6 single tests)

20 : 80                                 2.43 (1 single tests)

30 : 70                                 2.30 (1 single tests)

40 : 60                                 1.88  (1 single test)

50 : 50                                  – 1) (1 single test)

60 : 40                                   – 2) (1 single test)

70 : 30                                  – 2) (1 single test)

80 : 20                                  – 2) (1 single test)

90 : 10                                  – 2) (1 single test)

1) reaction (flame) stopped after 59 s at 50 mm distance, no further propagation of burning

2) reaction (flame) stopped after removing the gas burner flame (no spreading of fire).

Interpretation of results:

GHS criteria not met

Conclusions:

According to the test results the test item has no oxidizing properties according to the definition in the Commission Regulation (EC) No. 440/2008.

Executive summary:

Test on oxidising properties of tin sulfide was performed according to EU Method A.17. The highest burning rate of 2.99 mm/s was obtained with the mixture of 10 % sample : 90 % cellulose. This rate was definitely lower than the highest rate of the tested reference mixtures (3.23 mm/s). Therefore the assessment of the sample is “no oxidizing properties”.

Description of key information

According to the test results the test item has no oxidizing properties according to the definition in the Commission Regulation (EC) No. 440/2008.

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Additional information

Test on oxidising of tin sulfide was performed according EU Method A.17. The highest burning rate of 2.99 mm/s was obtained with the mixture of 10 % sample : 90 % cellulose. This rate was lower than the highest rate of the tested reference mixtures (3.23 mm/s). Therefore the assessment of the sample is “no oxidizing properties”.

Justification for classification or non-classification

Based on the results of the "oxidising properties" test, the test item tin sulfide is not classified according to Regulation (EC) No. 1272/2008 (CLP) with respect to oxidising properties.
