GB/T 34208-2017 Translated English of Chinese Standard. (GBT 34208-2017, GB/T34208-2017, GBT34208-2017): Iron and steel - Determination of antimony and tin content - Inductively coupled plasma atomic emission spectrometric methodhttps://www.chinesestandard.net, 02.06.2018 - 16 Seiten This Standard specifies the method for the determination of antimony and tin content using the inductively coupled plasma atomic emission spectrometric method. This Standard applies to the determination of antimony and tin content in carbon steel and low alloy steel of chromium content (mass fraction) less than 1.50% and nickel content (mass fraction) less than 2.00%: the measuring range of antimony (mass fraction) is 0.002 0% ~ 0.12%; the measuring range of tin (mass fraction) is 0.002 0% ~ 0.13%. |
