Evaluation

If the test item does not propagate combustion along 200 mm of the pile within the 4 minutes test period the test item is considered ‘not highly flammable’.

 

Results

In contact with the flame of the gas burner the test item melted, and turned into a white residue. After removal of the ignition source, no propagation of combustion of the test item was observed.

Interpretation of results:
non flammable
Remarks:
Migrated information Not highly flammable
Conclusions:
No propagation of combustion of the test item along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained the test item is considered ‘not highly flammable’.
Executive summary:

The preliminary screening test was performed for the determination of the flammability of 2,2-Bis[[3-(dodecylthio)-1-oxopropoxy]methyl]propane-1,3-diyl bis[3-(dodecylthio)propionate].

 

Study performed in accordance with the following guidelines:

European Community (EC), EC no. 440/2008, Part A: Methods for the Determination of Physico-Chemical Properties, Guideline A.10: “Flammability (Solids)”, Official Journal of the European Union no. L142, May 31, 2008.

United Nations (UN), UN no. ST/SG/AC.10/11/Rev.5: Recommendations on the Transport ofDangerous Goods, Part III: Classification Procedures, Test Methods and Criteria Relating to Class 2,Class 3, Class 4, Division 5.1, Class 8 and Class 9, Test N.1: “Test Method for Readily Combustible Solids”, 2009.

 

No propagation of combustion of the test item along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained the test item is considered ‘not highly flammable’.

Justification for classification or non-classification

The substance is not classified as flammable under CLP as it does not fulfil the requirements for flammability classification.
