Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2002-05-15 (experimental phase)
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Version / remarks:
EEC Directive 92/69
Deviations:
no
GLP compliance:
yes (incl. QA statement)
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

The test substance is not "highly flammable" according to the criteria of the guideline.

Interpretation of results:
GHS criteria not met
Conclusions:
1,3-Dimethyl-4 -Aminouracil is not "highly flammable" according to the criteria of the guideline.
Executive summary:

The determination of the flammability of the test item was performed in accordance with the EEC Directive 92/69, Part A, Methods for the determination of physico-chemical properties, A.10 "Flammability (solids)", EEC Publication No. L383, December 1992.

1,3-Dimethyl-4 -Aminouracil could not sustain a burning reaction during the preliminary test (contact time of about 2 minutes). No main test was performed.

In conclusion, 1,3-Dimethyl-4 -Aminouracil could not sustain a burning reaction during the preliminary test and is therefore not "highly flammable" according to the criteria of the guideline.

Description of key information

Flammability

- not highly flammable, 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 (EU method A.10, GLP)

- Brief burning and rapid extinction was observed, not considered highly flammable. (EU method A.10, GLP)

- Based on chemical structure pyrophoric properties are not to be expected. (Expert judgement)

- Based on chemical structure water reactivity is not to be expected. (Expert judgement)

- not flammable (Expert judgement)

Key value for chemical safety assessment
