Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
February 10, 2016
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Version / remarks:
1985
GLP compliance:
no
Test procedure:
burning rate test: preliminary screening test
Burning time:
ca. 385 s

The specimen in contact with the flame of the Bunsen burner after 10 seconds begins to melt superficially, the fusion product is brown; It is observed a high flame ( till 5 cm) deep yellow color. The time for the propagation of combustion to the length of 20 cm specimen is equal to about 385 seconds. The combustion residue appears as a brown crust having the consistency of the wax.
The test substance is not easily flammable according to the aforementioned method, since the propagation in the preliminary screening test takes place in a time of 385 seconds and this value is higher than the limit of 240 seconds.

Interpretation of results:
other: Not classified according the CLP Regulation (EC 1272/2008)
Conclusions:
Not flammable
Executive summary:

Additional information

The test substance has been checked for its flammability according to the 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 test of flammability was conducted according to the EU A.10 Method (1985).

Since the propagation in the preliminary screening test takes place in a time of 385 seconds, i.e. above the threshold limit of 240 sec,

then the substance should not be considered as highly flammable and no further testing is required. On this basis the substance is not classified according to the CLP Regulation.
