Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
The study was conducted between 06 September 2018 and 07 September 2018.
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)
Specific details on test material used for the study:
Identification: Reaction mass of crystalline magnesium silicate and crystalline silicon and synthetic amorphous silicon dioxide
Appearance/Physical state: Black powder
Batch: Y180510A
Purity: 95 min wt%
Expiry date: 31 May 2019
Storage conditions: Room temperature in the dark
Key result
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 failed to ignite during the 2 minutes that the Bunsen flame was applied.

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

Interpretation of results:
GHS criteria not met
Conclusions:
The test item has been determined to be not highly flammable as it failed to ignite 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.
