ASTM E359 Results and Interpretation

The results of ASTM E359 analysis are reported in terms of the concentration of each element found in the alloy usually in parts per million (ppm) or percentage by weight. Such results are crucial for determining whether an alloy of magnesium satisfies any requirement of an industry application in which composition significantly affects performance. This quality control would ensure the proper performance of magnesium alloy in its intended application using results from the test.

Standard addresses the chemical composition of magnesium and magnesium alloys by various instrumental methods. ASTM E1473 is one such test, focusing on the chemical analysis of magnesium and its alloys using various instrumental techniques.

Uses of ASTM E359 Testing in Specific Industries

This test method is used in industries whose products contain magnesium alloys. Prominent uses include aerospace, automotive, and electronics. In aerospace, its applications are structural components with important low-weight and high-strength features. In the automotive world, magnesium alloys are used in the engine to create weight reduction and fuel efficiency features. 

Materials Tested by ASTM E359

The materials tested using this test method include magnesium and its alloys. The most common magnesium alloys tested include AZ91D, AM60, and ZK60. These are just a few. However, their elemental content is tested to ensure that it falls within acceptable limits. Other product lines include automobiles, aerospace, and even consumer electronics. 

Safe and Best Practices in ASTM E359 Testing

In this test method, safety handling precautions are covered during the preparation of samples. Precautions are taken to avoid exposure to harmful hydrochloric or nitric acids by wearing gloves, goggles, and proper ventilation. 

Atomic Absorption Spectrometry Process and Data Collection

The primary technique applied in this test method is atomic absorption spectrometry (AAS), an all-purpose technique for trace element analyses of metals. In this process, the sample is dissolved in acid and atomized in a flame or graphite furnace. Then, light travels through the vaporized sample, wherein the absorption of particular wavelengths is measured. 

Significance of ASTM E359 and Atomic Absorption Spectrometry

This standard test method is important because detecting minor and trace elements in the materials ensures their safety and efficiency in applications in industries such as aerospace and automobile, which require precise material performance in using the various materials in their applications.
