ASTM E107 Chromium Content in Recycled Alloys
The ASTM E107 standard provides a method for determining the chromium content in recycled alloys. This testing is critical for ensuring that recycled materials meet specified quality and performance criteria, which are essential for maintaining product integrity across various industries.
Chromium is an important element used in alloy steel to improve its resistance to corrosion and wear. In many cases, recycling of metals not only reduces the demand on natural resources but also helps manage waste streams effectively. However, the chromium content in recycled materials can vary widely depending upon the original source of the metal being recycled.
The ASTM E107 method employs energy-dispersive X-ray fluorescence (EDXRF) spectrometry to measure chromium content within a specific range. This technique is non-destructive and provides rapid results suitable for quality control applications in manufacturing processes involving recycled metals.
For accurate testing, the specimen must be prepared carefully according to ASTM E107 guidelines. Specimens are typically pressed into pellets or discs that allow for even distribution of chromium throughout the sample. After preparation, these specimens undergo analysis using EDXRF equipment calibrated specifically for the chromium content range required by ASTM E107.
The test results provide quantitative data on chromium levels present in the recycled alloy samples. These measurements help manufacturers verify compliance with standards such as ISO 9001 and ASME Section VIII Division II, ensuring that their products meet specified quality thresholds.
| Parameter | Description |
|---|---|
| Energy Range | The EDXRF spectrometer measures X-rays in the energy range of 5 to 70 keV. |
| Spectral Resolution | With a resolution better than 130 eV, this method ensures precise measurement of chromium content. |
| Data Points | A minimum of 20 data points are collected during each analysis run to ensure reliable results. |
The precision and accuracy achieved through ASTM E107 ensure that recycled alloys comply with industry standards, thereby enhancing product reliability and safety. Compliance with such tests is crucial for maintaining trust among customers who rely on consistent quality from suppliers.
In summary, the ASTM E107 method offers a reliable approach to measuring chromium content in recycled alloys, supporting sustainability efforts while ensuring product integrity and meeting regulatory requirements.
