Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

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

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 test:

The test substance could not be ignited with a flame. The main test was therefore unnecessary. The test substance is not a readily combustible solid.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Under the study conditions, the substance was not considered to be a readily combustible solid.

Executive summary:

A study was conducted to determine the flammability of the test substance according to EU Method A.10, in compliance with GLP. In case of powder or granular substances, the product is loosely filled into a mould, made of metal. It has a length of 250 mm, and a triangular cross section with an inner height of 10 mm and an width of 20 mm. In both sides of the mould in a longitudinal direction two metal sheets are mounted as lateral limitations which project 2 mm beyond the upper portion of the triangular cross section. The mould is then dropped three times from a height of 2 cm onto a solid surface. If necessary, the mould is filled up again. Then the lateral limitations are removed and the excess of substance scraped off. A non-combustible and non-porous plate is placed on top of the mould, the apparutus is inverted and the mould is removed. As ignition source a flame is used to ignite the pile at one end. A preliminary test was performed to see if the substance burns over a distance of 200 mm during 4 min. The test substance could not be ignited with a flame. The main test was therefore unnecessary. Under the study conditions, the substance was not considered to be a readily combustible solid (Hoffmann, 1999).
