    Standard Test Methods for Tension Testing of Metallic Materials

    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.
    NOTE 1—These test methods are the metric companion of Test Methods E 8. Committee E-28 was granted an exception in 1997 by the Committee on Standards to maintain E8 and E8M as separate companion standards rather than combining standards as recommended by the Form and Style manual.
    NOTE 2—These metric test methods are essentially the same as those in Test Methods E 8, and are compatible in technical content except that gage lengths are required to be 5D for most round specimens rather than 4D as specified in Test Methods E 8. 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.
    NOTE 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 A 370 and Test Methods B 557M.
    NOTE 4—Room temperature shall be considered to be 10 to 38°C unless otherwise specified.
    1.2 This 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.

    In reporting values of elongation, give both the original gage length and the percentage increase. If any device other than an extensometer is placed in contact with the specimen’s reduced section during the test, this shall also be noted.

    When the specified elongation is greater than 3 %, fit ends of the fractured specimen together carefully and measure the distance between the gage marks to the nearest 0.25 mm for gage lengths of 50 mm and under, and to at least the nearest 0.5 % of the gage length for gage lengths over 50 mm. A percentage scale reading to 0.5 % of the gage length may be used.

    When the specified elongation is 3 % or less, determine the elongation of the specimen using the following procedure, except that the procedure given in 7.11.2 may be used instead when the measured elongation is greater than 3 %.

    Prior to testing, measure the original gage length of the specimen to the nearest 0.05 mm.

    Remove partly torn fragments that will interfere with fitting together the ends of the fractured specimen or with making the final measurement.

    Fit the fractured ends together with matched surfaces and apply a force along the axis of the specimen sufficient to close the fractured ends together. If desired, this force may then be removed carefully, provided the specimen remains intact.

    The use of a force of approximately 15 MPa has been found to give satisfactory results on test specimens of aluminum alloy.

    Measure the final gage length to the nearest 0.05 mm and report the elongation to the nearest 0.2 %.

    Elongation measured per paragraph may be affected by location of the fracture, relative to the marked gage length. If any part of the fracture occurs outside the gage marks or is located less than 25 % of the elongated gage length from either gage mark, the elongation value obtained using that pair of gage marks may be abnormally low and non-representative of the material. If such an elongation measure is obtained in acceptance testing involving only a minimum requirement and meets the requirement, no further testing need be done. Otherwise, discard the test and retest the material.

    Elongation at fracture is defined as the elongation measured just prior to the sudden decrease in force associated with fracture. For many ductile materials not exhibiting a sudden decrease in force, the elongation at fracture can be taken as the strain measured just prior to when the force falls below 10 % of the maximum force encountered during the test.

    Elongation at fracture shall include elastic and plastic elongation and may be determined with autographic or automated methods using extensometers verified over the strain range of interest (see 5.4). Use a class B2 or better extensometer for materials having less than 5 % elongation, a class C or better extensometer for materials having elongation greater than or equal to 5 % but less than 50 %, and a class D or better extensometer for materials having 50 % or greater elongation. In all cases, the extensometer gage length shall be the nominal gage length required for the specimen being tested.Due to the lack of precision in fitting fractured ends together,the elongation after fracture using the manual methods of the preceding paragraphs may differ from the elongation at fracture determined with extensometers.
