Reference
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
December 29, 2015
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:
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

The flammability test was negative.

During the test, the substance melts and burns producing black smoke. However, the flame does not propagate to the adjacent powder.

Interpretation of results:
other: non flammable according to the CLP Regulation (EC 1272/2008)
Conclusions:
Non flammable.
Executive summary:

Method

Flammability test was carried out according to the EU Method A.10.

Result

Non flammable.

Description of key information

Non flammable.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Flammability test carried out according to EU method A.10.

Justification for classification or non-classification

According to the CLP Regulation (EC 1272/2008) powdered, granular or pasty substances or mixtures (except powders of metals or metal alloys — see 2.7.2.2) shall be classified as readily combustible solids when the time of burning of one or more of the test runs, performed in accordance with the test method described in Part III, sub-section 33.2.1, of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, is less than 45 seconds or the rate of burning is more than 2.2 mm/s.

The screening test on flammability was negative, thus the substance is not classified as flammable according to the CLP classification criteria.
