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 UN‐RTDG, 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

Justification for classification or non-classification

According to the burning rate test N.1 of the UN‐RTDG, 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 to be labelled as such a substance since it cannot be ignited by a hot flame of a small gas burner.
