Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- April 15, 1991
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- GLP compliance:
- yes
- 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:
- other: not classified, according to the CLP Regulation (EC) No 1272/2008
- Conclusions:
- Not considered as highly-flammable.
- Executive summary:
The substance was assessed for its flammability in a test, according to the EU Method A.10. The substance was tested as delivered, in a preliminary test by using a 40 mm pile. In the main test, a 250 mm pile was used but the burning time over 100 mm of pile was not possible to measure.
During the preliminary test it was noted that the substance could be ignited, but the flame didn't spread out.
Conclusion
The substance is not considered as highly-flammable.

Justification for classification or non-classification
According to the CLP Regulation (EC) No 1272/2008, flammable solids are classified according to their burning rate (or burning time) obtained in six test runs. Furthermore, a flammable solid means a solid which is readily combustible, or may cause or contribute to fire through friction. Readily combustible solids are powdered, granular, or pasty substances or mixtures which are dangerous if they can be easily ignited by brief contact with an ignition source, such as a burning match, and if the flame spreads rapidly.
The substance during the preliminary test showed that it can be ignited, however t the flame does not spread out. This screening test could be an indication that the substance is not highly flammable. Furthermore, in the main test the burning time over 100 mm length could not be measured probably for the reason that the flame does not propagate until 100 mm.
In conclusion, the substance does not meet the criteria to be classified as flammable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
