ASTM E3047 Equipment and Sample Preparation Guide
ASTM E3047 requires a spark atomic emission spectrometer (Spark-AES) with a spark source, analytical stand, argon gas flow system, spectrometer, and measuring and control systems. Prepared specimens, calibration reference materials, and drift-correction samples are analyzed to determine the elemental composition of the nickel alloy. The ASTM E3047 comprises the following equipment and sample procedure-
| Specimen Details | Technicians prepare nickel alloy specimens that are free of porosity or inclusions and suitable for the spark atomic emission spectrometer. |
| Specimen Dimensions | The specimen must be large enough to cover the specimen orifice of the analytical stand and must fit the specimen stand. |
| Specimen Preparation | Technicians prepare the specimen surface by grinding or lathe turning to produce a clean, flat analytical surface. |
| Instrumentation | The test uses Spark-AES equipped with a spark source, analytical stand, argon gas flow system, spectrometer, and measuring and control systems. |
Testing Procedures and Requirements for ASTM E3047
This test standard subjects nickel alloy specimens to a Spark-AES spectrometer. Technicians prepare the specimen surface, set the required instrument conditions, and perform controlled spark burns. Another test related to ASTM E3047 is ASTM E415 for Atomic Emission Vacuum Spectrometric Analysis of Carbon and Low-Alloy Steel. The ASTM E3047 standard comprises the following test procedure-
| Specimen Preparation | Technicians prepare the nickel alloy specimen by grinding or lathe turning to obtain a clean, flat analytical surface. Technicians prepare the nickel alloy specimens and ensure that the analytical surface is clean and flat before measurement. |
| Specimen Installation | Technicians place the prepared specimen over the orifice of the instrument analytical stand, ensuring there are no gaps at the specimen edge. |
| Calibration | Technicians measure calibration reference materials and develop calibration curves relating analyte intensity to analyte mass fraction. |
| Spark Measurement | Technicians place the prepared specimen on the analytical stand and perform at least two separate burns. |
| Result Determination | Technicians compare the measured specimen intensity with the calibration curve and determine the analyte results as a mass fraction (%) or mg/kg. |
ASTM E3047 Testing Process and Data Collection
The analyst selects representative nickel alloy specimens and prepares their surfaces to obtain a clean, flat analytical surface. Technicians then set up the Spark Atomic Emission Spectrometer with the required analytical conditions and calibration parameters. Technicians place the prepared specimens on the analytical stand and perform at least two separate spark burns, repositioning the specimen between burns so the ablated areas do not overlap. The measured intensities are evaluated and compared with the calibration curves to determine the elemental composition. Technicians then calculate the mean results and report analyte concentrations as mass fraction (%) or mg/kg.
Common Challenges and Troubleshooting
Accurate ASTM E3047 results require proper specimen preparation, appropriate calibration reference materials, and stable Spark-AES operating conditions. The selection of analytical lines and potential spectral interferences may affect the measured intensities. Technicians need to check the spectrometer before testing. Laboratories can also achieve reliable results when specimens, calibration reference materials, and drift-correction samples are prepared using the same procedure.
