Flammability

Link to relevant study record(s)

Reference

Reference 1

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

Principles of method if other than guideline:

The applied testing method (UN N.1) is identical to the testing method in EC Test Procedure A 10 'Flammability (Solids)’ (sole exception: wetting solution was added beyond the timing zone).

GLP compliance:

yes (incl. QA statement)

N,N-dicyclohexyl-2-benzothiazolesulfenamide is not a readily combustible solid.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

DCBS is classified as not readily combustible solid when tested according to UN Test Procedure N.1

Executive summary:

DCBS is classified as not readily combustible solid when tested according to UN Test Procedure N.1 (Currenta, 2010).

Reference 2

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied

the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

Reference 3

Endpoint:

pyrophoric solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Description of key information

a) Determined according to the method UN N.1 (Burning-Rate-Test), DCBS is not a readily combustible solid (Currenta 2010)
b) In accordance with section 1 of REACH Annex XI, the study 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.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

DCBS 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).
