ASTM E9
Full Name
ASTM E9 – Standard Test Methods of Compression Testing of Metallic Materials at Room Temperature
Scope
ASTM E9 outlines standardized procedures for performing compression tests on metallic materials at room temperature. This test method is crucial for determining a material’s compressive properties, such as compressive yield strength, compressive strength, and modulus of elasticity. Understanding these properties is essential for predicting a material’s behavior under compressive loads in various applications.
Key aspects of ASTM E9 include:
- Specimen preparation: the standard provides detailed guidance on machining test specimens from different product forms like plates, sheets, bars, and tubes. It emphasizes the importance of proper surface finish, parallelism, and dimensional tolerances to ensure accurate and repeatable test results.
- Test machine requirements: ASTM E9 specifies requirements for the testing machine, including its capacity, accuracy, and speed control. This ensures that the applied compressive force is controlled and measured accurately.
- Test procedure: the standard outlines a step-by-step procedure for conducting the compression test. This includes placing the specimen in the testing machine, applying the load at a controlled rate, and recording load and deformation data.
- Calculation of compressive properties: ASTM E9 provides formulas for calculating key compressive properties from the obtained load-deformation data. These calculations enable a quantitative assessment of the material’s response to compressive forces.
- Reporting requirements: the standard specifies essential information that must be included in the test report. This includes specimen details, test conditions, calculated compressive properties, and any observed anomalies during testing.
