Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 04 June 2018 - 04 July 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
- Version / remarks:
- Rev. 6 (2015)
- Deviations:
- no
- GLP compliance:
- yes
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
- Interpretation of results:
- other: not classified based on GHS or CLP criteria
- Conclusions:
- The substance is not a flammable solid.
- Executive summary:
A GLP study according to UN Test N.1 was performed. In the preliminary screening test, the substance does not ignite and does not propagate combustion either by burning with flame or smouldering within 2 minutes and the substance melted in contact with the flame. The substance is concluded to be not a flammable solid.
Reference
In contact with the flame of the gas burner the test item melted and turned into a light yellow residue and white smoke was observed.
Description of key information
A GLP study according to UN Test N.1 was performed. In the preliminary screening test, the substance does not ignite and does not propagate combustion either by burning with flame or smouldering within 2 minutes and the substance melted in contact with the flame. The substance is concluded to be not a flammable solid.
As the substance is completely molten at 160 °C, no testing for self-heating is required. (mp = 22.5 °C, substance decomposes from 145ºC)
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
No propagation of combustion of the test item along 200 mm length of the pile within 2 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test item is considered ‘not flammable’.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
