ASTM B954-23 pdf free download – Standard Test Method For Analysis Of Magnesium And Magnesium Alloys By Atomic Emission Spectrometry.
This method outlines the procedure for analyzing magnesium and its alloys using atomic emission spectrometry. The magnesium sample for analysis can take the form of a chill cast disk, casting, sheet, plate, extrusion, or other wrought shapes. The elements covered in this method are specified in the table provided below.
Note 1: The mass fraction ranges indicated in the scope are approximations derived from observations of two manufacturers and data supplied by an atomic emission spectrometer supplier. The ranges presented for each element do not represent the exact analytical range for that element. The practical analytical range may vary depending on the capabilities of the individual instrument, the spectral characteristics of the specific element wavelength utilized, and the availability of suitable reference materials.
This method is primarily suitable for analyzing chill cast disks as outlined in Sampling Practice B953. Other forms may also be analyzed, provided they meet certain criteria: (1) they are sufficiently substantial to prevent excessive heating, (2) they allow machining to create a clean, flat surface for a secure seal between the specimen and the spark stand, and (3) reference materials of similar metallurgical conditions and chemical compositions are accessible.
This standard does not cover all safety concerns associated with its application. Users are responsible for establishing appropriate safety, health, and environmental practices and determining the relevance of regulatory constraints before use. Specific safety and health guidelines are detailed in Section 10.
