Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 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
- GLP compliance:
- no
- Specific details on test material used for the study:
- Name sodium 3-sulfobenzoate
Batch no. 170103
CAS No. 17625-03-5
Purity > 99.0% (Titration with NaOH, Glass indicating electrode, Calomel reference electrode)
Expiry date 14. Feb. 2019
Storage Room Temperature (20 ± 5°C), keep away from humidity - 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:
- not classified based on GHS criteria
- Conclusions:
- The test item was heated with the flame of a gas burner for two minutes. Since ignition did not occur within two minutes, the test substance was classified as not highly flammable (for EU regulations) and non-flammable solid (for UN regulations), resp. No determination of burning rate was necessary.
- Executive summary:
The determination of the flammability of sodium 3-sulfobenzoate has been performed according to EU A.10. In the preliminary Screening Test the substance was heated with the flame of a gas burner for two minutes. Since ignition did not occur within two minutes, the test substance was classified as not highly flammable (for EU regulations) and non-flammable solid (for UN regulations), resp. No determination of burning rate was necessary.
Reference
Safety Pre-Test
The test substance melted into a black liquid. The liquid expanded and a black residue was observed.
Preliminary Screening Test
The test substance melted into a black liquid. The liquid expanded and a black residue was observed. In the second experiment, the test substance melted into a brown-black liquid. The liquid got bubbles, when the flame of the burner was taken away from the liquid. No signs of ignition were observed.
