1.1 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.
Dec 19, 2007 You can probably obtain sub-size tensile specimens for tensile testing in accordance with ASTM E8. Based on what you reported regarding a CT specimen, and attempting to remove standard or subsidize tensile specimens, I would not recommend it. ASTM A370 tensile testing is very similar to ASTM E8 in that the specimens are either round or flat. Flat samples are generally tested with serrated jaw inserts while round samples use a V-insert. The size of the jaw inserts determines the allowable sample thickness within the grips. Specimen Dies Direct from the Manufacturer. As a manufacturer of both dies and presses, Pioneer-Dietecs has everything you need for your die-cutting process. With over 50 years of experience machining dies, specimen dies are our specialty, with close tolerances that far exceed standards for enhanced sharpness and long die life. ASTM E8 Metal Tensile Testing. Measure and record the specimen dimensions necessary to determine the cross sectional area at its smallest point. The original cross sectional area is used for all engineering stress calculations. Use ink and a scribe or punch to place gage marks on the test specimen at the appropriate gage length. Specimens for ASTM D638 are dumbbell-shaped with either a 25 mm or 50 mm gauge length; a 50 mm gauge length is recommended. Gauge length changes with ASTM E83 Class B-2 accuracy; an absolute accuracy of 10 μm for a 50 mm gauge length and relative accuracy within ±0.5% are required by ASTM D638 for measuring the tensile modulus of elasticity.
1.2 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 industry-wide agreement to keep the pressing of the material to a specific projected area and density.

1.3 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.

1.5 The values stated in SI units are to be regarded as separate from inch/pound units. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.6This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
