Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2019-04-08 to 2019-10-24
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Version / remarks:
(EC) No. 440/2008
GLP compliance:
no
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

Screening test

In contact with a hot flame of a small gas burner the substance cannot be ignited (burning number BZ = 1). The test has been repeated six times. The full burning rate test is therefore not required.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item does not have to be considered as a flammable solid and a full burning rate test is not necessary.
Executive summary:

According to the burning rate test N.1 of the UNRTDG, GHS Regulation (EC) No 1272/2008 and Council Regulation (EC) No 440/2008 test A.10, the test item is not a flammable solid of Division 4.1 and does not have be labelled as such a substance since it cannot be ignited by a hot flame of a small gas burner.

Description of key information

The test item is not a flammable solid.

Key value for chemical safety assessment

Flammability:
not classified
