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 27 October 2017 to 08 November 2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Results are difficult to interpret because at every run the burning rate decreases
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Version / remarks:
- 2016
- Deviations:
- no
- 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:
- yes
- Remarks:
- It was technically not possible to prepare a wetting zone, since loss from the sides of the pile could not be avoided due to the high solubility of the test item. Therefore, no wetting zone could be applied beyond the 100 mm timing zone.
- GLP compliance:
- yes
- Specific details on test material used for the study:
- Test item is a powder.
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- 94 s
- Remarks on result:
- other: substance could be ignited; it propagated combustion by burning with flame along 200 mm of the powder train in less than 2 minutes.
- Key result
- Test procedure:
- burning rate test over 100 mm length
- Burning time:
- 58 s
- Moisture (wt %):
- 0
- Remarks on result:
- other: 83, 67, 55, 48 and 38 seconds of burning over 100 mm were measured in Test 1, 2, 3, 4 and 5, resp.
- Remarks:
- The average of all runs was taken
- Interpretation of results:
- other: equivocal
- Remarks:
- because it was technically not possible to prepare a wetting zone.
- Conclusions:
- The flammability cannot be well assessed in the present test.
- Executive summary:
The flammability of the substance was determined in a GLP study according to EC A.10 and UN Test N.1. The result of the screening test was showed that in 94 s burning occurred over 50 mm and therefore a full flammability test was needed to accurately have a burning rate. It was technically not possible to prepare a wetted zone because the substance solubilised in water. This may have impacted the results. The time of burning over a distance of 100 mm, after the pile had burned a distance of 80 mm, decreased with each run going from 83 seconds to 38 seconds. This decreasing order is remarkable when the runs are performed independantly and therefore considered equivocal. The average running time is 58 s and this value will be used for the flammability assessment.
Reference
The test item melted during the test and finally burned with an orange/yellow flame and turned into a black residue. Grey/black smoke was observed.
Description of key information

The result of the screening test was showed that in 94 s burning occurred over 50 mm and considered positive.

Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
The flammability of this substance could not be assessed with the flammability test on solids because no wetting zone could be prepared due to the substance solubilising in water. The final conclusion of non flammable is based on the average burning rate of five runs instead of using the lowest one because the individual runs were decreasing every time these were conducted.
A very similar substance (Ethyl maltol) with a melting point of 86oC and a similar density (0.5% < 100 um) was not flammable which supports the absence of flammability of Maltol (Ethyl maltol at the ECHA website: https://echa.europa.eu/nl/registration-dossier/-/registered-dossier/22549/4/14,
EC number: 225-582-5|CAS number: 4940-11-8)
Justification for classification or non-classification
The substance is equivocal in the UN Test N.1, the average burning rate of 58 s is used. This information is supported with information from Ethyl maltol, which is not flammable. Therefore classification is not needed according to EU CLP 1272/2008 and its amendments.
