Max. rate of gas release:
1 L/kg h
Remarks on result:
reaction with water (not further specified)
Remarks:
after the addition of water the test item reacts abruptly with a gas emission, but no spontaneous ignition could be observed. because of the strong reaction with water the test item does not emit gas after 10 seconds anymore. The emitted gas was not flammable.
