Key result
Test procedure:
burning rate test: preliminary screening test
Burning time:
0 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
Remarks:
In the preliminary screening test the gas flame was applied for 5 minutes and no ignition was observed.

Since the test substance did not ignite during the preliminary screening test it should not be considered as highly flammable and no further testing is required.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test substance molybdenum disilicide (MoSi2) is non-combustible.
Executive summary:

The test substance molybdenum disilicide (MoSi2) is non-combustible.

Description of key information

The test substance Molybdenum disilicide (MoSi2) is non-combustible.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

During the preliminary screening test the gas flame was applied to the substance MoSi2 for 5 minutes and no ignition occurred. Therefore, the target substance was classified as non-combustible and no further testing was required.
