Flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2009-12-18
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Deviations:
- not specified
- GLP compliance:
- no
- Test procedure:
- burning time (test type not further specified)
- Remarks:
- or specified in description of method (migrated information)
- Burning time:
- 82 s
- Test procedure:
- ignition time on contact with air
- Remarks:
- Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
- Remarks on result:
- no ignition on contact with air (not further specified)
- Remarks:
- corresponding to 'no' in migrated source record.
- Test procedure:
- ignition time on contact with air
- Remarks:
- Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
- Remarks on result:
- no ignition on contact with air (not further specified)
- Remarks:
- corresponding to 'no' in migrated source record.
- Interpretation of results:
- non flammable
- Remarks:
- Migrated information
- Conclusions:
- The shortest burning rate was determined to be 82 s. The individual results were 117, 90, 70, 75, 70 and 70 seconds.
- Executive summary:
Octylphenol was tested according EU method A10 "Flammability (solids)" 31.05.2008. The preliminary screening test showed that the test substance propagates burning of a 200 mm length of the powder train in less than 4 minutes, therefore a burning rate test was conducted. Octylphenol was judged to be "non-flammable" as the shortest burning time in up to 6 tests was more than 45 s.

| 3. burning rate | 110 s |
| 4. burning rate | 93 s |
| 5. burning rate | 95 s |
| 6. burning rate | 100 s |
Moisture content of the sample: < 0.1 wt.%

Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
