Results and discussion
Flammable solids
- 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
Any other information on results incl. tables
Preliminary Screening
The pile failed to ignite during the 5 minutes that the Bunsen flame was applied. The result of the preliminary screening test obviated the need to perform the main test.
Applicant's summary and conclusion
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The test item has been determined to be not highly flammable as it failed to ignite in the preliminary screening test.
- Executive summary:
The study was conducted in compliance with Good Laboratory Practice.
Copper dichromium tetraoxide was found to be not highly flammable, using a procedure designed to be compatible with Method A.10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.
