ASTM E9 Compression Testing of Metallic Materials at Room Temperature
ASTM E9 is a set of standard test methods providing yield strength, the upper yield strength, the Young's modulus, the stress-strain curve, and the compressive strength for metallic materials. ASTM E9 standard comprises apparatus, specimens, and process for axial-load compression testing of metallic materials at room temperature. The values stated in inch-pound units are to be regarded as standard.

Introduction to ASTM E9 Test Method
The data obtained from ASTM E9 compression test includes the yield strength, the yield point, Young’s modulus, the stress-strain curve, and the compressive strength for metallic material specimens. This strength is dependent on total strain and specimen geometry. It is of interest in the analyses of structures subject to compressive or bending loads or both and in the analyses of metalworking and fabrication processes that involve large compressive deformation. Buckling and barreling can complicate results and should be minimized. The ASTM E9 test method is not used for materials that fail in compression by a shattering fracture. MaTestLab has the best network of testing labs in the USA to carry out ASTM E9 test for clients
Compressive properties are useful for structures subject to compressive forces or bending moments and metal works and fabrication processes involving large compressive deformation such as forging and rolling. On the other hand, for brittle or nonductile metals that fracture in tension at stresses below the yield strength, ASTM E9 compression test can obtain the strain range of the stress-strain data.
ASTM E9 Standard Test Method
Loading Rate
The standard recommends an acceptable loading rate depending on material qualities and intended results, with special consideration given to high-strength materials.
Deformation Measurement
Extensometers or other comparable instruments are used. The placement of the extensometer and factors for calibration are specified.
Testing Conditions
The test environment, typically room temperature, is specified in the standard. Additionally, the suggestion is made to run additional tests to confirm that the results are repeatable and reliable.
ASTM E9 Test Specimen
Specimen Details
The ASTM E9 standard recognizes three forms of solid cylindrical test specimens for metallic materials: short, medium-length, and long. Additionally, rectangular or sheet-type specimens can be used in compression testing, particularly when lateral support is required.
Specimen Dimensions
ASTM E9 provides suggested dimensions for solid compression test specimens in the form of cylindrical cylinders, while rectangular or sheet-type specimens depend on the jig used for lateral support
Specimen Preparation
Surface requirements include minimal variation in diameter, width, or thickness; a coaxial centerline within 0.01 inches (0.25 mm); a surface finish of 63 in. (1.6 m) or better; flatness and parallelism of ends to within 38 of an arc; edges of rectangular specimens with a width of material machined away equal to the thickness, and gage length location away from ends.
ASTM E9 Test Results
ASTM E9 includes calculating the modulus of elasticity, determining the yield strength by the offset method, determining the yield point, and determining the compressive strength. The yield point is the maximum stress obtained just prior to the sudden drop in stress, and the compressive strength is the maximum stress at or before fracture, as determined by dividing the maximum load by the cross-sectional area. For ductile materials, compressive strength may be determined from the stress-strain diagram at a specified total strain.
Other Tests Related to ASTM E9
ASTM E9 is related to standards such as ASTM E4 for force verification of testing machines and ASTM E6 terminology relating to methods of mechanical testing.
