Reference
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1-9-217 to 2-10-2017
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
GLP compliance:
yes (incl. QA statement)
Specific details on test material used for the study:
Sample Name: CETATS
CAS Number: 138-32-9
Lot no: 99D1100U
Description: white crystalline powder with little to no odour
Expiry date: 23 April 2020
Test procedure:
burning rate test: preliminary screening test
Burning time:
> 4 min
Moisture (wt %):
0.08
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
Interpretation of results:
not classified based on GHS criteria
Conclusions:
In an EU A10 test using a fire train mould (250mm long) and a flame from a gas burner (min diameter 5mm) the test substance melted to a yellow/brown liquid. Once ignited, it produced an orange localised flame which extinguished a few seconds after the test flame was removed.

The substance is therefore not highly flammable.
