Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.10 (Flammability (Solids))
Version / remarks:
EEC/79/831, Annex V
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.12 (Flammability (Contact with Water))
Deviations:
no
GLP compliance:
yes
Test procedure:
burning rate test: preliminary screening test
Burning time:
0 s
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

As ignition source a flame and a glowing platinum wire was used to ignite the pile at one end. The substance could not be ignited. The test substance is not a readily combustible solid in the sense of Guideline EEC/79/831 test A.10.

Within approximately 60 hours, no gas evolution was registered in the A.12 test. After this gas evolution of 5.5 cm3/kg.h within a period of 44 hours was observed.

Study period: 104 hours

Ambient temperature: between 20.4 and 23.3 deg C

 

The test substance is not regarded as hazardous according to the test method, A.12.

Interpretation of results:
GHS criteria not met
Conclusions:
The test substance is not a readily combustible solid, nor is there any concern for the liberation of flammable gas following exposure to water / moisture.
Executive summary:

As ignition source a flame and a glowing platinum wire was used to ignite the pile at one end. The substance couldn't be ignited. The test substance is not a readily combustible solid in the sense of Guideline EEC/79/831 test A.10.

Within approximately 60 hours, no gas evolution was registered in the A.12 test. After this gas evolution of 5.5 cm³/kg*h within a period of 44 hours was observed.

Study period: 104 hours

Ambient temperature: between 20.4 and 23.3 deg C

 

The test substance is not regarded as hazardous according to the test method, A.12.
