Materials and methods

Test guideline
Qualifier:
according to
Guideline:
other: VDI 2263 sheet 1
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 spreading 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:
The substance has not to be classified as combustible solid
Executive summary:

The substance was tested for flammability according to VDI 2263. After applying an ignition source (flame or hot platinum wire) the sample showed no reaction at room temperature. Only the melting was observed. The combustion behaviour of the substance can be described with combustion number 1 (no ignition)
