Reference
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From October 2009 to March 2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
no
GLP compliance:
yes (incl. certificate)
Key result
Test procedure:
burning time over 250 mm for metal powders or metal alloys
Burning time:
2 min
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 substance did not ignite from the flame of the burner in three preliminary tests, instead it was found to be melting in the formed path. Therefore, it was not considered to be highly flammable and no further tests were performed.

Interpretation of results:
GHS criteria not met
Conclusions:
Under the study condictions, the substance was not considered to be highly flammable.
Executive summary:

A study was conducted to determine the flammability of the test substance in accordance with EU Method A.10. In a preliminary test, the substance was formed into an unbroken strip or powder train about 250 mm long , 20 mm wide and 10 mm high on a non-combustible, non-porous and low heat-conducting base plate. A hot flame from a gas burner (minimum diameter 5 mm) was applied to one end of the powder train until the powder ignited or for a maximum of 2 minutes. The substance did not ignite from the flame of the burner. Instead, it was found to be melting in the formed path. Under the study condictions, the substance was not considered to be highly flammable and no further tests were performed ( Frączak, 2010).

Description of key information

The flammability was determined according to EU Method A.10 (Frączak, 2010).

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Justification for classification or non-classification

The substance is not highly flammable, as shown by to EU Method A.10., and does not require classification for this endpoint according to CLP (EC 1272/2008) criteria.
