Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
december 2017 - january 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Specific details on test material used for the study:
Information as provided by the Sponsor.
Identification: Triazolone
CAS No: 930-33-6
Appearance/Physical state: White solid
Batch: 0727/16
Purity: 99%
Expiry date: 04 January 2020
Storage conditions: Room temperature in the dark
Key result
Test procedure:
burning rate test: preliminary screening test
Burning time:
< 2 min
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 pile began to melt then briefly ignited with a blue flame which emitted light grey smoke. The flame self-extinguished without propagating combustion.

The result of the preliminary screening test obviated the need to perform the definitive test.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item is not classified as a flammable solid.
Executive summary:

Not classified as a flammable solid, using a procedure designed to be compatible with Test N.1 of the United Nations Recommendations on the Transport of Dangerous Goods manual of Tests and Criteria, 5th revised edition 2009 and Regulation (EC) No 1272/2008 of 16 December 2008 on Classification Labelling and Packaging of Substances and Mixtures.
