Foreword

This section drafted in accordance with GB/T 1.1-2009 given rules. The partial modification of the use of ISO 11652 "Steel cobalt content by flame atomic absorption spectrometry," the structure and technical content (except for some Normative references outside) consistent with. For ease of use, this section made the following editorial changes. a) Remove the preface to international standards; b) reference standards with national standards instead of the corresponding international standards. This portion of the GB/T 223.65-1988 compared, mainly to do with the following modifications. --- The measurement range of 0.01% to 0.5% was adjusted to 0.003% to 5.0%; --- Sample processed by the addition of different acid depending on the sample to dissolve the unity of hydrochloric acid, nitric acid, perchloric smoke; --- Break calibration curve by the calibration curve to unity. This part is proposed by the China Iron and Steel Association. This part of the National Steel Standardization Technical Committee (SAC/TC183) centralized. This part mainly drafted by. National Stainless Steel Products Quality Supervision and Inspection Center, National Steel Products Quality Supervision and Inspection Center, steel Fe Institute. The main drafters of this section. Chenan Yuan, Ma Yuanyuan, Ganzheng Bin, Yaocheng Hu, Luo Qianhua, Cuiqiu Hong. This part of the standard replaces the previous editions are. GB/T 223.65-1988. Determination of steel and alloy cobalt content Flame Atomic Absorption Spectrometry Warning. Use of this section shall be a person experiences regular laboratory work. This section does not indicate that all possible security issues. Users have the responsibility to take appropriate safety and health practices and to ensure compliance with the conditions relevant national regulations.
