Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

Experimental starting date: 08 May 2017 Experimental completion date: 18 August 2017

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)

Specific details on test material used for the study:

Batch: 020021X3
Purity: 99.9%
Expiry date: 25 August 2017
Storage conditions: Room temperature in the dark

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

Preliminary Screening

The pile ignited briefly with an orange flame that emitted grey smoke, but failed to propagate combustion before self-extinguishing.

The result of the preliminary screening test obviated the need to perform the main test.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item has been determined to be not highly flammable as it failed to propagate combustion in the preliminary screening test.

Executive summary:

Flammability (Solids). Not highly flammable, using a procedure designed to be compatible with Method A.10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

The test substance was found to be not highly flammable, using a procedure designed to be compatible with Method A.10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.
