Reliability:

Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
The preliminary screening test was performed for the determination of the flammability of the test
substance.
The test substance was loosely filled into an aluminum mould of 250 mm long with a triangular crosssection
of inner height of 10 mm and width of 20 mm. On both sides of the mould in a longitudinal
direction two metal plates were mounted as lateral limitations that project 2 mm beyond the upper
edge of the triangular cross section. The mould was dropped three times from a height of 2 cm onto a
solid surface. If necessary, the mould was filled up again. The lateral limitations were removed and the
excess substance was scraped off. A non-combustible and non-porous plate was placed on top of the
mould. The complete assembly was inverted and the mould removed.
A flame of a gas burner was applied to one end of the test substance pile for 2 minutes. The pile was
visually interpreted for propagation of combustion either by burning with a flame or smouldering. If
applicable, the time of burning over a distance of 200 mm was measured after the pile had burned a
distance of 50 mm.

Results and discussion

Flammable solids
Key result
Test procedure:
burning rate test: preliminary screening test
Burning time:
> 4 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

Applicant's summary and conclusion

Interpretation of results:
not classified based on GHS criteria
Conclusions:
No propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes
was observed. According to the guidelines, performance of the burning rate test is not required. Based
on the results obtained, the test substance is considered „not highly flammable
