Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 19.02.2018 - 19.02.2018
- 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)
- GLP compliance:
- no
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- >= 10 - <= 15 s
- 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:
- Methylhydroquinone is not to be classified as flammable acc. to GHS-criteria.
- Executive summary:
The test item Methylhydroquinonemelted and showed only a local burning for 10 – 15 s with short propagation of about 10 mm.
Reference
Preliminary Test
The test item melted and the molten test item started to burn locally after applying the flame. After a short propagation of about 10 mm the local burning extinguished after 10 – 15 s.
Main Test
In the preliminary test the test item melted and showed only a local burning with a propagation of about 10 mm within 10 – 15 s. Thus, the performance of the main test was not necessary.
Description of key information
The test item melted and the molten test item started to burn locally after applying the flame. After a short propagation of about 10 mm the local burning extinguished after 10 – 15 s.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
The test item 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.
Therefore, methylhydroquinone is not to be classified as flammable acc. to GHS-criteria.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
