Galvanizing and galvanized steel plating Chemical analysis methods1 ScopeThis section provides inductively coupled plasma atomic galvanized and galvanized steel plating chemical analysis method for determining emission spectrometry. This section applies to the determination of the surface of the sample rule. Determination of the range in Table 1. Table 1 Determination of elements content range Elements in the range of (mass fraction) /% Si 0.001 ~ 5.00 Ni 0.001 ~ 5.00 Cu 0.001 ~ 5.00 Fe 0.001 ~ 10.002 Normative referencesThe following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. Laboratory use specifications and test methods GB/T 6682 Analysis JJG015 inductively coupled plasma atomic emission spectrometer test procedures3 Method summarySamples immersed in stripping solution to dissolve the sample surface zinc coating, zinc coating before and after weighing the quality of the sample is dissolved. The sample stripping solution Injected into the plasma flame, and this light source, the corresponding element in the plasma spectrometer at the wavelength of the light intensity measured, determined from the standard curve Given its content, the chemical elements in order to account for the quality of the content of the measured sample loss calculated as the percentage content of the coating chemical elements.4 Reagents and materialsUnless otherwise indicated in the analysis using only recognized as analytical reagents and GB/T 6682 provisions of secondary water. 4.1 high-purity metallic zinc (Zn > 99.98%). 4.2 high-purity aluminum (aluminum content > 99.98%). 4.3 hydrochloric acid (ρ = 1.19g/mL). 4.4 nitric acid (ρ = 1.42g/mL). 4.5 hydrochloride (13). hydrochloric acid (4.3) and diluted with water to 1.3 ratio. 4.6 hydrochloride (11). hydrochloric acid (4.3) and diluted with water to 1 to 1 ratio. 4.7 20% sodium hydroxide solution. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 2951-2011_English be delivered?Answer: Upon your order, we will start to translate SN/T 2951-2011_English as soon as possible, and keep you informed of the progress.
