Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 16 January 2019 t0 13 February 2019
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- ca. 236.06 s
- Key result
- Test procedure:
- burning rate test over 100 mm length
- Burning time:
- ca. 83.34 - ca. 102.88 s
- Conclusions:
- Under the study conditions, the test substance was determined to be not highly flammable.
- Executive summary:
A study was conducted to determined the flammability of the test substance, C16-18 TMAC (100% active), according to the EU Method A10, in compliance with GLP. During the study, the burning rate of the preliminary screening test showed the combustions propagated the 200 mm in more than 2 minutes (3 min and 56.06 sec) (UN-regulations) but less than 4 minutes (EU-regulations). The shortest burning time showed the combustions propagated the 100 mm in more than 45 seconds (1 min 23.34 sec and 1 min 42.88 sec). Therefore, the test substance should be considered as not highly flammable (for EU regulations) and as non-flammable solid (for UN regulations). No observations were made which might cause doubts concerning the validity of the study outcome. Under the study conditions, the test substance was determined to be not highly flammable (Krebs, 2019).
- 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

Results
Safety Pre-Test
First, a safety test was performed. A small amount of the test substance was heated on a magnesia groove with a gas burner in order to derive safety precautions. The test substance melted into a clear and white-coloured liquid. The liquid burned with an orange flame. Light black-coloured residue was observed.
Preliminary Screening Test
In the preliminary screening test following the EU and UN method, the test item was heated with the flame of a teclu burner. When ignited with the flame of a teclu burner, the test substance started to burn with an orange and sooting flame. The test item melted and carbonized. Black residue was observed. The combustion with flame of the test item propagated the 200 mm within 3 min and 56.06 sec. Therefore, a burning rate for EU-regulations were performed. The burning rate showed the combustions propagated the 100 mm between 1 min 23.34 sec and 1 min 42.88 sec. Therefore, the burning rate according to the EU-regulation was determined.

Discussion
The burning rate of the preliminary screening test showed the combustions propagated the 200 mm in more than 2 minutes (UN-regulations) but less than 4 minutes (EU-regulations). The shortest burning time showed the combustions propagated the 100 mm in more than 45 seconds. Therefore, the test item RM1008688 should be considered as not highly flam- mable (for EU regulations) and as non-flammable solid (for UN regulations). No observations were made which might cause doubts concerning the validity of the study outcome.
Description of key information
The flammability of the test substance was determined according to EU Method A.10 (Krebs, 2019).
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
A study was conducted to determined the flammability of the test substance, C16-18 TMAC (100% active), according to the EU Method A10, in compliance with GLP. During the study, the burning rate of the preliminary screening test showed the combustions propagated the 200 mm in more than 2 minutes (3 min and 56.06 sec) (UN-regulations) but less than 4 minutes (EU-regulations). The shortest burning time showed the combustions propagated the 100 mm in more than 45 seconds (1 min 23.34 sec and 1 min 42.88 sec). Therefore, the test substance should be considered as not highly flammable (for EU regulations) and as non-flammable solid (for UN regulations). No observations were made which might cause doubts concerning the validity of the study outcome. Under the study conditions, the test substance was determined to be not highly flammable (Krebs, 2019).
Justification for classification or non-classification
Based on the results of the recently conducted study, the test substance does not warrant a classification for flammability according to the EU CLP criteria (Regulation EC 1272/2008).
