Specific details on test material used for the study:

Appearance: solid
Storage conditions: room temperature

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

The test substance glowed red on application of the flame, but did not burn. No further testing was necessary.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Fe3P was found not to be highly flammable.

Reference 2

Endpoint:

pyrophoric solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Reference 3

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture

Description of key information

Fe3P was found not to be highly flammable.

Fe3P does not have any phyrophoric properties.

Fe3P does not emit flammable gases in contact with water.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

A flammability determination was performed as part of a package of Physicochemical testing (Huntingdon Life Sciences, 2011, Study FGE0002). The flammability was determined according to EU Method A10, and the study was conducted in compliance with GLP.

Fe3P was found not to be highly flammable.

Justification for classification or non-classification

Fe3P showed no evidence of flammability when assessed according to EU test methods A10. On this basis it may be concluded that classification as flammable is not required. This conclusion applies to the following Physical Hazards:

Flammable solids

Pyrophoric solids

Substances and mixtures which in contact with water emit flammable gases

Note that as Fe3P is a solid under normal conditions, and will not be used as an aerosol, the following classifications do not apply:

Flammable Gases

Flammable Liquids

Flammable Aerosols

Pyrophoric Liquids
