Preliminary test


The preliminary screening test showed a superficial propagation of the flame. The flame ceased after 135 seconds. Therefore the full test was carried out.


 


Train test


The mixtures in the range of 10 to 50 % sample / cellulose exposed a very slow combustion. The flame ceased without reaching the end of the line, but with a higher advance with rising percentage of the sample.


The mixtures containing 60 to 90 % sample / cellulose showed a slow propagation of the flame. They reached the end of the line within 2 to 9 minutes. The shortest time to propagate burning for a 200 mm powder train was 169 seconds.


In Table1 the results of the three mixtures with the shortest burning rates are listed. The validity criteria were fulfilled, i. e., none of the final 6 runs with a mixture of sample / cellulose 90 / 10 differed by more than 10 % from the mean.

Since the burning rate of the test item Sulfosuccinic (FA C12-18)E, 2Na was shorter than the burning rate from the reference sample the test item has no oxidizing properties according to the definition in the Council Regulation (EC) No 440/2008 EEC.


 

Interpretation of results:
GHS criteria not met
Executive summary:

In the non-GLP Klimisch 1 study from Bütfering (2012) the oxidizing properties of Sulfosuccinic (FA C12-18)E, 2Na were analysed according to EU method A.17. The fasted burning rate of the test item was 1.18 mm/s and hence slower than the burning rate of the reference material (1.23 mm/s). Since the burning rate of the test item Sulfosuccinic (FA C12-18)E, 2Na was significantly shorter than the burning rate from the reference sample the test item has no oxidizing properties according to the definition in the Council Regulation (EC) No 440/2008EEC.

The results of this study are considered relevant and reliable for the risk assessment.

Additional information

In the non-GLP Klimisch 1 study from Bütfering (2012) the oxidizing properties of Sulfosuccinic (FA C12-18)E, 2Na were analysed according to EU method A.17. The fasted burning rate of the test item was 1.18 mm/s and hence slower than the burning rate of the reference material (1.23 mm/s).

The results of this study are considered relevant and reliable for the risk assessment.

Justification for classification or non-classification

Since the burning rate of the test item Sulfosuccinic (FA C12-18)E, 2Na was significantly shorter than the burning rate from the reference sample the test item has no oxidizing properties according to the definition in the Council Regulation (EC) No 440/2008EEC.
