Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

other: UN Test Procedure N.1 (33.2.1.4.1)

GLP compliance:

yes (incl. QA statement)

The substance in its delivery state was measured. The test substance melted when approached by the ignition flame. The substance didn't burn down or burn up. No further testing was required.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

2,2'-Dithiobis(benzothiazole) is classified as not readily combustible solid.

Executive summary:

2,2'-Dithiobis(benzothiazole) is classified as not readily combustible solid when tested according to UN Test Procedure N.1 (Currenta 2010).

Description of key information

a) MBTS is classified as not readily combustible solid when tested according to UN Test Procedure N.1 (Currenta, 2010).
b) In accordance with section 1 of REACH Annex XI, the study on pyrophoric properties does not need to be conducted. 
Experience in production and handling: substance is known to be stable at room temperature.
c) In accordance with section 1 of REACH Annex XI, the study does not need to be conducted. 
No flammability in contact with water: The substance contains no metals or metalloids and therefore will not release flammable gases in contact with water.

Justification for classification or non-classification

MBTS is not readily combustible solid, no pyrophoric property, and no flammability in contact with water; and hence no classification according to both Directive 67/548/EEC and GHS (Regulation EC 1272/2008).
