Description of key information

Flammability was assessed in three experiments:



  • touching TI with heated Pt-Wire

  • touching TI with open butane flame

  • filling TI into a heated red glowing iron bowl


In the first experiment no ignition could be observed.


In the other two experiments a short ignition and directly extinguishment was observed.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

Under the experimental conditions the Test Item for did not burn or burning did not propagate.


The Test Item does not have to be calassified as flammable solid.
