To fully appreciate the contents of the ASTM E1251-17a PDF, one must understand the physics driving the analysis.

Spark Atomic Emission Spectrometry (Spark-AES) is an analytical technique where an electrical spark is generated between a counter electrode and the metal sample. This spark excites the atoms on the sample's surface, causing them to emit light at characteristic wavelengths. By measuring the intensity of these wavelengths, technicians can determine the exact concentration of various elements within the alloy.
