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 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
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
Endpoint:
self-heating substances / mixtures
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
other:
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Guideline study
Qualifier:
according to guideline
Guideline:
other: UN Test Procedure N.1
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
yes
Remarks:

GLP compliance:
not specified

The substance in its delivery state was measured. The test substance melted when approached by the ignition flame. The substance did not burn down or burn up. No further testing was required. TETD is classified as not readily combustible solid when tested according to UN Test Procedure N.1.

Interpretation of results:
other: Not readily combustible solid

Description of key information

Non flammable

No pyrophoricity

No flammability on contact with water

Not self-heating

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Tetraethylthiuram disulfide is classified as not readily combustible solid.

The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification:

No propagation of burning in a test according to EU Method A.10. Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected. The substance is not self-heating.

Justification for classification or non-classification

No classification as the substance is a non flammable solid. Based on the chemical structure flammability in contact with water and pyrophoricity are not expected.
