Spectrographic analysis of bismuth-tin eutectic alloys by spark-ignited low-voltage ac-arc excitation
Spectrographic method determines individual stainless steel components in molten bismuth-42 w/o tin eutectic to determine the solubility of Type 304 stainless steels. It utilizes the high sensitivity and precision of the spark-ignited, low-voltage ac-arc excitation of samples rendered homogeneous by dissolution.

Testing the flammability of materials exposed to arcs
Apparatus tests flammability and ignition characteristics of materials in close proximity to incandescent metal fragments or spalls ejected from intermittent short circuit arcs in air or oxygen rich atmospheres. It simulates a situation where an exposed live wire makes contact with a grounded member in areas containing organic matter.
