Reference 1

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2015-11-06

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

other: United Nations (2009): Recommendations on the TRANSPORT OF DANGEROUS GOODS, Manual of Tests and Criteria, 5th edition, Class 4, Division 4.1 - Flammable Solids, 'Test N.1: Test method for readily combustible solids', New York and Geneva

Deviations:

no

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

not specified

GLP compliance:

yes

Key result

Test procedure:

burning time (test type not further specified)

Remarks:

or specified in description of method

Burning time:

ca. 343 s

Remarks on result:

other: Result of the preliminary screening; acc. to guideline no further testing was necessary.

During a preliminary study (ignition of a rope of 250 mm length and ca. 100 mm² cross-section), the test substance was inflammable immediately by the hot flame of a gas burner and burned slowly and self-actingly with a yellow-orange, black sooting flame till end of testing (5 min 43 sec). In the area of the flame the test substance melted and re-solidified to a black-brown residuum.

Interpretation of results:

other: not classified as per CLP criteria

Conclusions:

Under the study conditions, the test substance was not found to be flammable. Therefore, it has been classified as "Not readily combustible solid of Division 4.1" in the sense of the test guideline UN Test N.1.

Executive summary:

A study was conducted to determine the flammability of the test substance, TMAC C (35.2% active), according to UN Test N.1. Guideline which is also equivalent and similar to the EU Method A.10, in compliance with GLP. During a preliminary study (ignition of a rope of 250 mm length and ca. 100 mm² cross-section), the test substance was inflammable immediately by the hot flame of a gas burner and burned slowly and self-actingly with a yellow-orange, black sooting flame till end of testing (5 min 43 sec). In the area of the flame the test substance melted and re-solidified to a black-brown residuum. Under the study conditions, the test substance was not found to be flammable. Therefore, it has been classified as "Not readily combustible solid of Division 4.1" in the sense of the test guideline UN Test N.1 (Thieu-Simchen, 2015).

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 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 liquids

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

Under the study conditions, the test substance was not found to be flammable.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The flammability was determined according to UN Test Guideline N.1, which is equivalent and similar to EU Method A.10 (Thieu-Simchen, 2015).

Justification for classification or non-classification

The test substance was found to be non-flammable in a guideline test; thus no classification is required for this endpoint according to EU CLP criteria (Regulation EC 1272/2008).
