This standard test method covers the determination of silicon in engine coolant concentrates by atomic absorption spectroscopy. Apparatus and reagents used for this test method include atomic absorption spectrometer, hollow-cathode lamp, reagent grade chemicals, standard silicon solution, ethylene glycol or propylene glycol, and sodium hydroxide. Silicon content shall be determined from an established standard curve and an atomic absorption spectrometer. A nitrous oxide-acetylene flame shall be used.
