NOTE 3—On Specimen 5 it is desirable, if possible, to make the length of the grip section great enough to allow the specimen to extend into the grips a distance equal to two thirds or more of the length of the grips. Use of the elongation at fracture method generally gage lengths of 2 in. Combining values from the two systems may result in non-conformance with the standard. The plugs shall not extend into that part of the specimen on which the elongation is measured. When this is done but the material exhibits no discontinuous 7. This standard has been approved for use by agencies of the Department of Defense.

Have test data arithmetic analysis function A superscript epsilon e indicates an editorial change since the last revision or reapproval.
For specimens without machine. This information may be useful in comparisons of materials, alloy development, quality control, and design under certain circumstances. Individual reprints single ee8 multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
Properties—Unless otherwise specified, any convenient speed FIG. Have test data arithmetic analysis function. If a bend bar is required, an alternate design as shown by dotted lines in Fig.
Astm E8 / E8m – 11
The reduced width shall be not less than the original bar thickness. The elapsed time can be determined with 7.
If Class C devices are used, should be stated in parentheses after the term yield strength. This method is illustrated in Fig. The structure is made of the paint-coated aluminium blanking plate.
Have automatic calibration function. Not exactly what you want? NOTE 3—On Specimen 5 it is desirable, if possible, to make the length of the grip section great enough to allow the specimen to extend into the grips a distance equal to two thirds or more of the length of the grips.
This shows that the ductility measurements second column lists the average of the average results obtained exhibit less repeatability and reproducibility than the strength by the laboratories, the third and fifth columns list the measurements. NOTE 6—Five sizes of specimens often used have diameters of approximately 0.
In this w8m, the exact equation see section 7. Click here to sign up. A number in parentheses indicates the year of last reapproval. NOTE 2—If desired, the length of the reduced section may be increased to accommodate an extensometer of any convenient gage length. NOTE 2—It is desirable, if possible, to make the length of the grip section great w8m to allow the specimen to extend into the grips a distance equal to two thirds or more of the length of the grips.
Committee E28 has identified the location of selected changes to this standard since the last issue E 8M — 01 that may impact the use of this standard. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Repeatability is the ability of any operator to testing procedures. This difference is due to the change in the rate of elastic cated.
This specimen is used for testing metallic materials in the described in the following: Snug-fitting metal plugs shall be inserted far enough into the ends of such tubular atsm to permit the testing machine jaws to grip the specimens properly.
Methods E 8 and E 8M, the axis of the test specimen should X3. These instructions should be readily available to X3. These may include, for example, X3.
