Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2009
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The EC method described in 440/2008 was used, but the description of the method is poor.
Reason / purpose for cross-reference:
reference to same study
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
not specified
GLP compliance:
not specified
Key result
Test procedure:
burning rate test: preliminary screening test
Burning time:
ca. 0
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
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record.

Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
other: Not applicable, the substance is a solid.
Remarks:
corresponding to 'no' in migrated source record.
Remarks on result:
other: No positive reactions based on practical experience.

Remarks on result:
other: No positive reactions based on practical experience.

It was not possible to ignite the sample during the preliminary test. The sample in contact with the flame was melting; there was no propagation of the combustion.

Executive summary:

Melamine is not highly flammable.

Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
supporting study
Reliability:
3 (not reliable)
Rationale for reliability incl. deficiencies:
other: The melting point is reported to ca. 250 °C, which is not in agreement with the actual range of ca. 350 to 361 °C. Typing error? Otherwise the score would be 4.

No continuous burning of melamine was obtained with a Pt-wire of >1000 °C.

Interpretation of results:
other: not highly flammable
Executive summary:

No continuous burning of melamine was obtained with a Pt-wire of >1000 °C.

Description of key information

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

The key study is the most recent study and was performed according to the current EU-guideline.

Justification for classification or non-classification

In both studies, melamine turned out not to be highly flammable.
