Flammability

Link to relevant study record(s)

Reference

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

24 June 2016 to 24 June 2016

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Key result

Test procedure:

burning time over 250 mm for metal powders or metal alloys

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 item did not ignite in either case during the preliminary test. Therefore, the substance is considered not to be highly flammable. Based on the results of the preliminary test, no main test was performed.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Under the conditions of the study, the test item did not ignite in either case during the preliminary test therefore the substance is considered not to be highly flammable.

Executive summary:

The flammability of the test material was investigated in a GLP study conducted in accordance to the standardised guideline EU Method A.10.

In preparation for the test, the sample filled into a mould and the mould was dropped three times from a height of 2 cm onto a solid surface and the mould was filled up again. The lateral limitations were removed and the excess substance scraped off. A non-combustible and non-porous plate was placed on top of the mould. This was inverted and the mould removed.

For the preliminary test, the flame from a gas burner was applied to one end of the powder train. The test was carried out in duplicate. The test item did not ignite in either case. Based on the results of the preliminary test no further testing was required.

Under the conditions of the study, the test item did not ignite in either case during the preliminary test therefore the substance is considered not to be highly flammable.

Description of key information

Flammability of Solids

Under the conditions of the study, the test item did not ignite during the preliminary test therefore the substance is considered not to be highly flammable.

Pyrophoricity

In accordance with Section 1 of Annex XI, it is considered justified to omit the testing for pyrophoric properties. Testing does not appear scientifically necessary, as based upon the chemical structure pyrophoric properties are not to be expected; furthermore, experience in use and experience of handling the substance indicates that it does not possess pyrophoric properties.

Flammability: Contact with Water

In accordance with Section 1 of Annex XI, it is considered justified to omit the testing for substances or mixtures which in contact with water emit flammable gases. Testing does not appear scientifically necessary as, based upon the chemical structure, water activity is not to be expected; this has been corroborated by the practical handling and use of the chemical over time.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The flammability of the test material was investigated in a GLP study conducted in accordance to the standardised guideline EU Method A.10. The study was assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).

In preparation for the test, the sample filled into a mould and the mould was dropped three times from a height of 2 cm onto a solid surface and the mould was filled up again. The lateral limitations were removed and the excess substance scraped off. A non-combustible and non-porous plate was placed on top of the mould. This was inverted and the mould removed.

For the preliminary test, the flame from a gas burner was applied to one end of the powder train. The test was carried out in duplicate. The test item did not ignite in either case. Based on the results of the preliminary test no further testing was required.

Under the conditions of the study, the test item did not ignite in either case during the preliminary test therefore the substance is considered not to be highly flammable.

Justification for classification or non-classification

In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to flammability.
