Materials and methods

Test guideline
Qualifier:
according to
Guideline:
other: company SOP "Werksrichtlinie"
Deviations:
not specified
Principles of method if other than guideline:
The procedure is very close to that described in VDI 2263 sheet 1 for determination of the combustibility index (burning rate).
The substance is deposited on a heated ceramic plate forming a rectangular pile of 4 by 2 cm. The sample is ignited at the smaller base by a glowing platinum wire or a small flame. Meltable products can be mixed with Kieselgur. The combustibility of the product is rated from 1 (=no ignition) to 6 (=very rapid combustion with flame propargation). From 1 - 3 no preading of fire is observed.
In case the combustibility index is >3 the burning rate is tested by measuring the velocity of a combustion zone propargating along an unbroken strip or a powder train about 250 mm long by 20 mm wide by 10 mm high on a non-combustible, non-porous and low hat-conducting base plate.
A powder is considered as highly flammable when the time to propargate 10 cm is less than 45 sec.

Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
Combustibility index 3, meaning only localized combustion or glowing with practically no spreading of a flame
Executive summary:

When tested as described above the substance has the combustibility index 3, meaning only localized combustion or glowing with practically no spreading of a flame
