Reference

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

December 17, 2015.

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with national standard methods

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Principles of method if other than guideline:

The test was performed according to the Dir. 92/69/EEC (OJ L383A) protocol.

GLP compliance:

no

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

Test substance did not catch fire. The substance did not propagate burning of a 200 mm length of the strip in less than four minutes, therefore burning rate test did not need to be performed.

The test is negative and the substance can be considered as non-flammable.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Test substance did not catch fire. The substance did not propagate burning of a 200 mm length of the strip in less than four minutes, therefore burning rate test did not need to be performed. The test is negative and the substance can be considered as non-flammable.

Executive summary:

Method:

The test was performed according to the internationally accepted testing method A.10.

Result:

Test substance did not catch fire. The substance did not propagate burning of a 200 mm length of the strip in less than four minutes, therefore burning rate test did not need to be performed.

The test is negative and the substance can be considered as non-flammable.

Description of key information

Non flammable

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Acid Brown 083 can be considered as a non-flammable substance

Justification for classification or non-classification

According to Regulation 1272/2008 (CLP) Powdered, granular or pasty substances or mixtures (except powders of metals or metal alloys — see 2.7.2.2 of CLP Regulation) 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.

Test substance did not catch fire. The substance did not propagate burning of a 200 mm length of the strip in less than four minutes, therefore burning rate test did not need to be performed.

Therefore the substance can be considered "not flammable" and no classification is warranted under CLP.
