Chemical composition is measured by spark optical emission spectrometry and wet methods to IS 8811, IS 9879, IS 228, IS 11035 and IS 2599, and to ASTM E415, E1086, E1999, E1251 and EN 15079: carbon, sulphur, phosphorus, manganese, silicon, chromium, nickel, molybdenum, copper and other elements.
Mechanical tests cover tensile strength, yield or proof stress and elongation, bend, Brinell, Rockwell and Vickers hardness, Charpy and Izod impact, and mass per metre, on structural steel, TMT bars, tubes and steel wire, to IS 1608, IS 1786, IS 1599, IS 1500 and ASTM A370. Metallography covers microstructure, grain size, inclusion rating, decarburisation and case depth.
