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. Specimen preparation is a critical part of metals testing, as improper preparation of specimens can yield unsatisfactory test results. Bluehill® Universal Software provides standard functions to perform metals tensile tests easily and accurately, and also includes pre-made methods for the major metals standards, including ASTM E8. Dec 07, 2017 When the correct tensile specimen dimensions are achieved, the micrometer dial will stop turning, thus preventing cutting an undersized test specimen. After removing the completed ASTM E8 or other specimen from the master template, the tensile bar is ready for immediate testing. 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.

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. A number in parentheses indicates the year of last reapproval. Windows 95 startup sound wav download. Any departure from this requirement may introduce bending stresses that are not included in the usual stress computation force divided by cross-sectional area. This requires that liners of several thicknesses be available to cover the range of specimen thickness.
This information may be useful in comparisons of materials, alloy development, quality control, and design under certain circumstances.
For short specimens and for specimens of many materials it is generally necessary to use machined test specimens and to use a special means of gripping to ensure that the specimens, when under load, shall be as nearly as possible in uniformly distributed pure axial tension see 5.
Proper alignment of wedge grips and liners is illustrated in Fig. The distance between spherical bearings should be as great as feasible. When liners are used behind the wedges, they must be of the same thickness and their faces must be flat and parallel. For best results, the wedges should be supported over their entire lengths by the heads of the testing machine.
Such interpretation is usually applicable to values for reduction of area reported in the literature when no further qualification is given. Parte 1 de 8 Designation: E8M Tensiont testing of metallic materials Juliano row Enviado por: Originally approved in This error increases to 2.
It is important, therefore, that care be exercised in the preparation of specimens, particularly in the machining, to maximize precision and minimize bias in test results. Astm c astm normas fibra de vidrio. Both of these gripping devices should be attached to the heads of the testing machine through properly lubricated sphericalseated bearings.
For proper gripping, it is desirable that the entire length of the serrated face of each wedge be in contact with the specimen. No further reproductions authorized. Combining values from the two systems may result in non-conformance with the standard.

NOTE 3—Punching or blanking of the reduced section may produce significant cold work asfm shear burrs, or both, along the edges which should be removed by machining. Current edition approved May 1, A superscript epsilon indicates an editorial change since the last revision or reapproval.
The test methods have been used extensively in the trade for this purpose. If, however, for any reason, one grip of a pair advances farther than the other as the grips tighten, an undesirable bending stress may be introduced.

The forces used in determining tensile strength and yield strength shall be within the verified force application range of the testing machine as defined in Practices E4. For measuring elongation at fracture with an appropriate extensometer, the gauge length of the extensometer shall be equal to the nominal gauge length required for the specimen being tested. Extensometers shall be used and verified to include the strains corresponding to the yield strength and elongation at fracture if determined.
NOTE 1—The effect of this eccentric force application may be illustrated by calculating the bending moment and stress thus added. Brittle Materials—A schematic diagram of a gripping device for threaded-end specimens is shown in Fig.

The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. For this reason, a small taper is permitted in the reduced section of each of the specimens described in the following sections.
C39M – 16 – Compressive Strength of Cylindrical Astm a Astm a For a standard These wedge grips generally furnish a satisfactory means of gripping long specimens of ductile metal.
The gauge length is the most significant difference between E8 and E8M test specimens. To ensure axial tensile stress within the gauge length, the axis of the test specimen should coincide with the center line of the heads of the testing machine.
