Results and discussion
Flammable solids
- Key result
- Test procedure:
- burning time (test type not further specified)
- 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
- Remarks:
- at room temperature
Any other information on results incl. tables
Propagation of a fire at local ignition
at room temperature: burns shortly, goes out quickly (combustion factor 2)
at 100°C: burns shortly, goes out quickly (combustion factor 2)
Check for flammability with different ignition sources
1. Cerium / iron sparks: no ignition
2. dual fuel: no ignition
3. gas flame, 2 cm:
< 1 s: no ignition,
> 1 s: ignition and becomes extinct
4. glow rod:
substance: ignition and becomes extinct
fumes: ignition
Applicant's summary and conclusion
- Interpretation of results:
- non flammable
- Remarks:
- Migrated information
- Conclusions:
- Trimethylhydroquinone is not classified as flammable substance since a fire at local ignition burns shortly but goes out quickly at room temperature.
- Executive summary:
A locally ignited spot of trimethylhydroquinone burns shortly but goes out quickly at room temperature.
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.
