Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.12 (Flammability (Contact with Water))

Deviations:

no

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.5 (Test method for substances which in contact with water emit flammable gases)

Qualifier:

according to guideline

Guideline:

other: United Nations (UN), UN no. ST/SG/AC.10/11/Rev.5: Recommendations on the Transport of Dangerous Goods, Appendix 6: “Screening Procedures”, 2009.

GLP compliance:

yes (incl. QA statement)

Remarks on result:

no reaction with water observed

Remarks:

The test substance does not contain groups that might lead to ignition in contact with water and/or to the evolution of a flammable gas.

A test substance is considered highly flammable when it ignites spontaneously in contact with water, or evolves a flammable gas at a minimum rate of ≥ 1 litre/kg of the substance per hour. The test substance does not contain groups that might lead to ignition in contact with water and/or to the evolution of a flammable gas. In conclusion, CH03220 is considered ‘not highly flammable’ in contact with water.

Interpretation of results:

not classified based on GHS criteria

Remarks:

Migrated information

Conclusions:

CH03220 is not highly flammable in contact with water, based on the molecular structure.

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

weight of evidence

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

no

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)

Version / remarks:

2009

GLP compliance:

yes (incl. QA statement)

Test procedure:

burning rate test: preliminary screening test

Burning time:

0 s

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

In contact with the flame of the gas burner the test substance melted and turned into a black residue with a blue and purple glow. White smoke was observed. After removal of the ignition source, no propagation of combustion of the test substance was observed.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The preliminary screening test was performed for the determination of the flammability of CH03220.
No propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test substance is considered ‘not highly flammable’.
