Flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From October 10, 2017 to October 10, 2017
- 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. 6.75 min
- Remarks on result:
- other: The test item left a black residue. Propagation of the combustion was less than 200 mm within four minutes.
- Interpretation of results:
- other: not classified based on CLP criteria
- Conclusions:
- Under the study conditions, the substance was not classified as a readily combustible solid.
- Executive summary:
A study was conducted to determine the flammability of the test substance, Quaternary ammonium compounds, N,N,N'-tris(hydroxyethyl)-N,N'-dimethyl-N'-tallow alkyltrimethylenedi-, bis(Me sulfates) (salts), according to the EU Method A.10 and UN Test Method N.1 as described in the UN Recommendations of Dangerous Goods, Manual of Tests and Criterian part III, sub-section 33.2.1.4. The test substance was spread on the plate in the form of a rope 250 mm in length with a cross section of about 1 cm2. The pile was arranged at right angle to the draught in the fume cupboard and the wind screen was erected. The flame of the teclu burner (minimum diameter 5mm) was used to ignite the pile at one end. After ignition of the test substance the burning time was determined for 230mm instead of 200mm. Propagation of the combustion was less than 200 mm within four minutes. Therefore, the test substance was classified as not highly flammable, and no determination of burning rate was necessary. Under the study conditions, the substance was not classified as a readily combustible solid (Krebs, 2018).
Reference
Safety pre-test:The test substance burned with an orange flame and expanded. The test substance left a black residue on the magnesia groove.
Preliminary screening test:The test substance started to burn immediately. The test substance burned slowly and the burning time for 200mm was 6min 44.91 seconds. The test substance left a black residue. Propagation of the combustion was less than 200 mm within four minutes. Therefore, no determination of the burning rate was necessary.
Results and Discussion:An ignition was observed throughout the course of the test.
The test substance should be considered as not highly flammable(for EU regulations)and as non-flammable solid (for UN regulations), because propagation of the combustion was less than 200mm within four minutes.
Description of key information
The flammability potential was determined according to EU Method A.10 and UN Method N.1 (Krebs, 2018).
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
During the study, the test substance propagation of the combustion was less than 200 mm within four minutes the study author concluded that no further testing is required. Based on the study result, the test substance was determined to be not highly flammable and considered as not classified based on EU CLP criteria.
