Principles of method if other than guideline:
The flammability of this powder was determined using a test mould and an ignition source. The test substance was loosely filled into the mould which was then dropped three times from a height of 2 cm onto the fume cupboard floor. The mould was removed from its holder and excess substance scraped off with a straight edge. An asbestos substitute board was placed on the mould, the apparatus inverted, and the mould removed. The board was then placed in the draught box in a fume cupboard. An attempt was made to ignite one end of the pile; the flame was held in position for two minutes.

Any other information on results incl. tables

The test substance melted to a black liquid, which burnt with an orange smoky flame, but did not propagate along the test pile.

Extremely flammable (Meth A9/A2): N
Highly flammable: N
Pyrophoric substance (A13): N
Highly flammable solid (A10): N
