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.

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.

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.
