no guideline available
Guideline:

Deviations:
not specified
Principles of method if other than guideline:
Sample of Chloranil could not be ignited in the screening test (Hartmann apparatus) with spark or glowing coil ignition. The full test in the closed apparatus (20 liter explosion sphere, chemical igniter with an energy of 2 x 1000 J) proved that a pressure rise above 0.5 bar was not observed. Chloranil is rated as a non combustible powder.

Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
No burning or glowing when ignited at ambient temperature, combustion number 1. The substance sublimates.
Executive summary:
Chloranil (2,3,5,6-tetrachloro-1,4-benzoquinone) was tested for its burning behaviour. No burning or glowing was observed when ignited at ambient temperature. Combustion number 1 (no reaction) was assigned to the test substance. The substance sublimates.
