Endpoint:
flammable solids
Type of information:
read-across based on grouping of substances (category approach)
Adequacy of study:
key study
Study period:
2015-11-06
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
KL2 due to RA
Justification for type of information:
Refer to the Quaternary ammonium salts (QAS) category or section 13 of IUCLID for details on the category justification.
Qualifier:
according to
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:
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:
Based on the results of the read across study, the test substance is not considered to be flammable.
Executive summary:

A study was conducted to determine the flammability of the read across substance, Coco TMAC (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 read across 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 read across substance melted and re-solidified to a black-brown residuum. Under the study conditions, the read across 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). Based on the results of the read across study, the test substance is not considered to be flammable.

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 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

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

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

Based on the results from the read across study, the test substance does not warrant a classification for flammability according to EU CLP criteria (Regulation EC 1272/2008).
