Foreword

This standard and ASTMB954-07 "magnesium and magnesium alloy atomic emission spectrometry standard analytical methods" (ASTMB954-07, Standard TestMethodforAnalysisofMagnesiumandMagnesiumAloysbyAtomicEmissionSpectrometry) a Consistency is not equivalent, on the main technical content and ASTMB954-07 basically the same. Structure and not correspond exactly to the preparation of the order. increase Plus warning prompt. Modify the terms of reference documents. Modifications to the instrument state control, reference materials and calibration requirements. Sample Type and refinement size. Modify sample analysis. By deleting some explanatory content. The excitation parameters and exposure time would read informative appendices. This standard is proposed and managed by the National Certification and Accreditation Administration Committee. This standard was drafted. People's Republic of China Liaoning Province Exit Inspection and Quarantine, Shimadzu (Hong Kong) Limited. The main drafters of this standard. Dong Xiuwen, Li Yan, An Guoyu, Zhang Bo. This standard is the first release of the entry-exit inspection and quarantine industry standards. Magnesium and magnesium alloy photoemission spectroscopy 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 Scope

This standard specifies the photoelectric magnesium and magnesium alloys emission spectroscopy method. This standard applies to magnesium die-cast magnesium alloy metal specimens, castings, sheet, extrusions or other specimens deformed shape or form and, measuring cell Su and range in Table 1.
