Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: Performed to current accepted guidelines.

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

no

GLP compliance:

no

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

During the preliminary screening test, the pile failed to ignite during the two minutes that the Bunsen flame was applied. The negative results of the screening test negated the need to perform the main test.

Interpretation of results:

non flammable

Conclusions:

Manganese oxide was found to be non-flammable in the preliminary screening tests. It was deemed unnecessary to perform further tests.
