GB/T 38939-2020 is the English-translated version of 镍基合金多元素含量的测定火花放电原子发射光谱分析法（常规法）.

GB/T 38939-2020 is the Chinese standard "Nickel-based alloy—Determination of multi-element contents—Spark discharge atomic emission spectrometric method(routine method)".

Its scope clause reads: This standard stipulates the determination of carbon, silicon, manganese, phosphorus, sulfur, chromium, copper, molybdenum, cobalt, aluminum, iron, titanium, by spark discharge atomic emission spectrometry.

Analytical methods for the content of boron, niobium, vanadium and zirconium. This standard applies to the determination of the content of each element defined in Table 1 in nickel-based alloys.
