Machining: Tensile Test Specimens • Plate, Sheet, And Round Specimens: • Plate Specimens - This specimen is used for testing metallic materials in the form of plate, shapes, and flat material having a nominal thickness of 3/16 inch or over. These specimens will be cut with the band saw or horizontal saw, depending on thickness, to approximate size. The finished dimensions will be attained by using belt sander for proper size. Care must be taken to avoid overheating during sanding. Figure 1 of this document shows the proper dimensions for flat specimens. • Sheet Specimens – This specimen is used for testing metallic materials in the form of sheet, plate, flat wire, strip, band, hoop, rectangles, and shapes ranging in nominal thickness from.005 to 5/8 inch.

These test methods cover the tension testing of metallic materials in any form at room temperature, specifically, the methods of determination of yield strength, yield point elongation, tensile strength, elongation, and reduction of area. The gauge lengths for most round specimens are required to be 4D for E8 and 5D for E8M. The gauge length is the most significant difference between E8 and E8M test specimens.

If using an extensometer, install the extensometer on the sample and begin loading the specimen. Step 5: Run the test until the sample either fails or fractures. Step 6: Remove the broken sample. If using an extensometer the software will automatically calculate the elongation, yield and modulus data.

Scope: These test methods cover the tension testing of metallic materials in any form at room temperature, specifically, the methods of determination of yield strength, yield point elongation, tensile strength, elongation, and reduction of area. The gauge lengths for most round specimens are required to be 4D for E8 and 5D for E8M. The gauge length is the most significant difference between E8 and E8M test specimens. Test specimens made from powder metallurgy (P/M) materials are exempt from this requirement by industrywide agreement to keep the pressing of the material to a specific projected area and density.

ASTM E8 Metal Tensile Testing ASTM E8 describes tensile testing of metals such as steel or metal alloys. This test determines important mechanical properties such as yield strength, ultimate tensile strength, elongation, and reduction of area. E8 tensile tests determine the ductility and strength of various metals when the materials undergo uniaxial tensile stresses. Such information is important for alloy development, design, quality control, and comparison of different sets of metals. An electro-mechanical or hydraulic universal testing machine equipped with the appropriate specimen grips, an extensometer and software capable of strain rate control and recording stress – strain data is necessary to conduct this test. If you need to conduct tensile tests according to ASTM E8, please read the entire specification from the relevant ASTM publication. ASTM E8 Metal Tensile Testing • Measure and record the specimen dimensions necessary to determine the cross sectional area at its smallest point.

Test specimens made from powder metallurgy (P/M) materials are exempt from this requirement by industrywide agreement to keep the pressing of the material to a specific projected area and density. Exceptions to the provisions of these test methods may need to be made in individual specifications or test methods for a particular material. For examples, see Test Methods and Definitions A370 and Test Methods B557, and B557M. Room temperature shall be considered to be 10 to 38°C [50 to 100°F] unless otherwise specified. The values stated in SI units are to be regarded as separate from inch/pound units.

Then install the specimen in the grips and start loading the sample. The speed of testing is generally specified in one of three manners: a) the rate of straining of the specimen; b) the rate of stressing of the specimen; or c) the rate of separation of the crossheads. In addition, the test rate is to remain constant through yield but can then be increased when determining ultimate tensile strength and elongation at break. See the ASTM E8 specification for more details.

These specimens will be cut with the band saw of horizontal saw depending on thickness to approximate size. The finished dimensions will be attained by using belt sander for proper dimensions.
