Description of key information

Liquid: The substance is a 25% solution in water, therefore performing a study is technically not feasible.

Solid: The test item (EC no. 215-686-9) was not highly flammable according to the definition in Council Regulation (EC) No 440/2008, method A.10.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Solid: The potential flammability of test item (EC no. 215-686-9) was tested according to Council Regulation (EC) No 440/2008, method A.10. About 30 g of the test item were used to form the test pile (excess substance included).After flame application to one end of the pile a melted mass was visible. This mass could not be ignited and was dark coloured after test end. According to the test guideline execution of the main test was not necessary. Thus, the test item was not highly flammable according to the definition in

Council Regulation (EC) No 440/2008, method A.10.

In addition, it is not expected that the substance has pyrophoric properties and reacts with water. Instead it is very well soluble in water.

Justification for classification or non-classification

No classification for this property is needed as the test item disodium tetrasulfide (EC no. 215-686-9) was not highly flammable according to the definition in Council Regulation (EC) No 440/2008, method A.10.

Based on the information indicated above, no classification is needed on flammability, pyrophoric properties and reactivity with water.
