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)
- Deviations:
- no
- GLP compliance:
- no
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- ca. 5 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:
- 2-Naphthol is not to be classified as flammable acc. to GHS-criteria.
- Executive summary:
The test item 2 -Naphthol melted and showed only a local burning for approx. 5 s without propagation.
The test item is classified as follows:
CLP Regulation EC 1272/2008: Annex 1: 2.7): The test item does not have to be classified as flammable solid according to CLP Regulation EC 1272/2008 Annex 1: 2.7.
Reference
Preliminary Test
The test item melted and the molten test item started to burn locally after applying the flame for about 30 s. After approx. 5 s burning time the local burning extinguished without further propagation.
Main Test
In the preliminary test the test item melted and showed only a local burning for approx. 5 s without propagation. Thus, the performance of the main test was not necessary.
Description of key information
A study was performed to determine the flammability of the test substance 2-naphthol. The study was conducted according to the UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids). The test substance 2-naphthol melted and only showed burning for approx. 5 s without propagation. It was concluded that the test item 2-naphthol does not meeting the criteria for classification as a flammable solid according to the CLP Regulation EC 1272/2008 Annex I: 2.7.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
The test item 2-naphthol melted and showed only a local burning for appox. 5 s without propagation. Therefore, the substance does not meet the criteria for classification according to the CLP regulation EC 1272/2008 Annex I: 2.7.
