(Steel sheet and strip and aluminum zinc-based coating glow determination of lead, cadmium and chromium content of Discharge Atomic Emission Spectrometry) ICS 77.080.01 H11 National Standards of People's Republic of China Steel sheet and strip aluminum and zinc-based coating of lead, Determination of cadmium and chromium content Glow Discharge Atomic Emission Spectrometry lead, cadmiumandchromiumcontens-Glowdischargeatomicemission Issued on. 2015-09-11 2016-06-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by China Iron and Steel Association. This standard by the National Steel Standardization Technical Committee (SAC/TC183) centralized. This standard is drafted by. Anshan Iron and Steel Group Corporation. The main drafters of this standard. in Yuan Jun, high-grade, Kang Dehua, Deng Junhua, Wanghai Dan, Li Feng, Xu Chengming. Steel sheet and strip aluminum and zinc-based coating of lead, Determination of cadmium and chromium content Glow Discharge Atomic Emission Spectrometry Warning --- personnel should use this standard regular laboratory work experience. This standard does not point out all possible security asked question. Users have the responsibility to take appropriate safety and health practices and to ensure compliance with the conditions relevant national regulations.1 ScopeThis standard specifies the glow discharge atomic content of lead, cadmium and chromium emission spectrometry. This standard applies to 1μm ~ 50μm coating thickness of the steel sheet and strip the surface of pure zinc, zinc, iron, zinc, aluminum, lead and cadmium zinc coating of chromium Determination of.

GB/T 6379.2 measurement methods and results of Accuracy (trueness and precision) - Part 2. Determine the standard measurement method to repeat Of the basic methods of reproduction GB/T 19502 Surface chemical analysis - Glow discharge optical emission spectrometry method General GB/T 20066 Steel and iron - Sampling and determination of the chemical composition of the sample with a sample preparation method Principle 3 The cathode having a flat surface of the sample as a glow discharge apparatus, the sample produces the female DC or RF glow discharge apparatus Pole sputtering, atomic measurement sample characteristic spectral line intensities. When the depth of analysis, emission intensity is recorded as a function of time, by means of a calibration curve, The intensity function of time into a function of the mass fraction of the sputtering depth. Known by measuring the composition of the reference sample sputtering rate can be built Li calibration system. According to the intensity of the relationship between line elements in the sample with the concentration calculation software obtained by coating samples were analyzed, the coating to be Measuring the content of the element.4 Reagents and materialsDischarge gas. typically high purity argon, 99.999% Purity.5 Instruments5.1 Overview Glow Discharge Atomic Emission Spectrometer is normally provided by Grimm type in GB/T 19502 or the like described glow discharge source (package Composition containing a DC or RF power supply mode) and simultaneous spectrometer detector. Spectrometer has been adapted to analyze elemental analysis of line. Diameter An anode within the range of 2mm ~ 8mm can be used. Distance between cathode and anode is generally between 0.1mm ~ 0.3mm.
