Any other information on results incl. tables

- A main test was not conducted, as the test item melted and changed the colour (from light yellow) to dark brown. The test substance could not be ignited.

Applicant's summary and conclusion

Interpretation of results:

non flammable

Remarks:

Migrated information

Conclusions:

As the test substance could not be ignited but melted and showed a change in colour it is cosidered as non-flammable.

Executive summary:

The determination of the flammability of the test item PM-6976 was performed in accordance with the EEC Directive 92/69 EEC, A.1O “Flammability (solids)” (1992) and GLP. As ignition source the flame of a gas-burner was used. In contact with the flame for 2 minutes, the test substance melted and changed its colour from light yellow to dark brown and could not be ignited. In conclusion, PM-6976 is not “highly flammable” according to the criteria of the directive.
