Summary This standard specifies a method for determining the content of cobalt, copper, chromium, iron, niobium, and nickel in high-temperature shape memory alloys using inductively coupled plasma atomic emission spectrometry (ICP-AES). This document applies to the determination of the content of cobalt, copper, chromium, iron, niobium, and nickel in high-temperature shape memory alloys. The determination range (mass fraction) for cobalt, copper, chromium, iron, and niobium is 0.0050%�C0.50%, and the determination range (mass fraction) for nickel is 1.00%�C10.00%.
