Description of key information

Due to the extreme conditions during manufacture (smelting at 1200 °C) it can be concluded that no functional groups which would contribute to pyrophoricity/combustibility/flammability of the substance are present in slags. Long-term experience in handling and use of slags confirms that flammability is not a concern for slags, tin-smelting. 
Against this background it can be concluded that performance of a study to determine the flammability of slags is not scientifically justified under REACH.
