Burning Behavior	Class	Comments
Test in delivery state at room temperature	BNA 1	The test sample melts on the ceramic plate. No ignition
Test at room temperature (dried state)	BNR 2	Test in pan. Brief ignition and rapid extinction.
Test at room temperature, sample mixed with 20 % silica	BNR S 3	Test in pan. Localized combustion or glowing with practically no spreading).
Test at a temperature of 100 °C	BN100 2	Test in pan. Brief ignition and rapid extinction.

Legend

BN = 1 (no ignition)

BN = 2 (brief ignition and rapid extinction)

BN = 3 (localized combustion or glowing with practically no spreading)

BN = 4 (glowing without sparks or slow decomposition without flame)

BN = 5 (burning with flame or spark generation)

BN = 6 (very rapid combustion with flame propagation or rapid decomposition without flame)

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

Non flammable substance

Executive summary:

Test developed according to VDI 2263, Part 1. The test is to determine if and to what extent a fire initiated by an external source will propagate through a dust layer. The prepared sample is placed on a ceramic plate in the shape of a pile covering an area of about 2 cm by 4 cm. A small flame as an ignition source is brought up to one end of the sample pile. The combustibility of the product is rated on a scale from 1 to 6 depending on the course of the reaction (BN = Burning number).

The test substance is considered as non flammable, because at 100 °C there are only localized combustion and/or glowing, with practically no spreading.

 

Conclusion

Non flammable
