Reference
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
January 24th, 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Qualifier:
according to
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Qualifier:
according to
Guideline:
EU Method A.10 (Flammability (Solids))
GLP compliance:
yes (incl. certificate)
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

The flammability of the test item was concluded during the preliminary test: the test item was not ignited, when the burner was kept in contact with the test item for 2 minutes and did not propagates 200 mm length within 4 minutes. So that burning rate test is not applicable for the test item.

Interpretation of results:
other: not classified, according to the CLP Regulation (EC) 1272/2008
Conclusions:
The test item is not highly flammable or non-flammable.
Executive summary:

The flammability of test item was determined in accordance with Official journal of the European Union, “EEC A.10. Flammability (Solids)”, 31 May 2008 and Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, sixth revised edition; Test N.1: Test method for readily combustible solids, 2015.

The flammability of the test item was concluded during the preliminary test because the test item was not ignited, when the burner was kept in contact with the test item for 2 minutes and did not propagates 200 mm length within 4 minutes.

Therefore, no additional investigations are needed.

Conclusion

The test item is not highly flammable or non-flammable.

Description of key information

UN Test N.1

Justification for classification or non-classification

According to the CLP Regulation (EC) No 1272/2008, 2.7 section, flammable solids, powdered, granular or pasty substances or mixtures 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.

In the flammability test performed, the substance did not propagate burning of a 200 mm length of the strip in less than four minutes, therefore the substance resulted non flammable.

In conclusion, Disperse Blue 354 does not meet the criteria to be classified as flammable, according to the CLP Regulation (EC) No 1272/2008.
