Spark testing Wikipedia

Spark testing is a method of determining the general classifiion of ferrous materials. It normally entails taking a piece of metal, usually scrap, and applying it to a grinding wheel in order to observe the sparks emitted. These sparks can be compared to a chart or to sparks from a known test sample to determine the classifiion.
