GB/T 38939-2020 (English Version) PDF

Scope: This standard specifies the analytical method for the determination of carbon, silicon, manganese, magnet, sulfur, chromium, copper, molybdenum, chromium, aluminum, iron, Yu, boron, vanadium and vanadium by the spark discharge atomic emission spectrometry controlled sample method. This standard is applicable to the determination of the content of each element defined in Table 1 in Zhao-based alloys. Table 1 Applicable scope and quantitative range of each element Note: The quantitative range is the content range of each element verified by precision testing; the applicable scope is based on instrument detection Within the range of capability determination, for the content section that has not been verified by precision testing, the laboratory must first conduct method confirmation when measuring samples with this content.
