Results and discussion

Flammable solids

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

Applicant's summary and conclusion

Interpretation of results:

not classified based on GHS criteria

Conclusions:

2,5-diphenyloxazole's famability was tsted in accordance with EU Method A.10 via a GLP certified laboratory. The substance did not pass the preliminary burning screening tests and therefore the substance is not classified under GHS (i.e. the substance is not highly flammable).

Executive summary:

2,5-diphenyloxazole's famability was tsted in accordance with EU Method A.10 via a GLP certified laboratory. The following preliminary screening test took place:

A mould (250 mm long x 20 mm wide x 10 mm high) was loosely filled with test item (tested as received). A non-combustible, non-porous board was placed onto the mould which was then inverted. The mould was removed and an air-rich Bunsen burner flame applied to one end of the pile for two minutes.

The substance did not pass the preliminary burning screening tests and therefore the substance is not classified under GHS (i.e. the substance is not highly flammable). No further testing was required.
