E — 07 fatigue test the permanent deformation of the unbroken but tested astj for example, percent change in cross-section area of test section should be reported.
These tests are conducted to examine and evaluate the behavior, susceptibility, and extent of resistance of certain materials to sharp-notch tension, tear, axial fatigue, strain-controlled fatigue, surface crack tension, creep e46-696, and residual strain.
ASTM’s fatigue and fracture standards provide the appropriate procedures for carrying out fatigue, fracture, and other related tests on specified materials. A number in parentheses indicates the year of last reapproval.
Electrical Standards and Magnetic Conductor Standards.
NOTE 1—The following documents, although not directly referenced in the text, are considered important enough to be listed in this practice: One set of strain gages should be placed at the center of the gage length to detect misalignment that causes relative rotation of the specimen ends about axes perpendicular to the specimen axis. The results may also be used as a guide for the selection of metallic materials for service under conditions of repeated direct stress.
Consumer Product Evaluation Standards. E – 10 See all versions E Ee1 E Redline Version E e1 E E This practice is limited to the fatigue testing of axial unnotched and notched specimens subjected to a constant amplitude, periodic forcing function in air at room temperature.
Paint Standards and Related Coating Standards. For cylindrical specimens, alignment should be checked by means of a trial test specimen with longitudinal strain gages placed at four equidistant locations around the minimum diameter.
Paper Standards and Packaging Standards. This practice is limited to the fatigue testing of axial unnotched and notched specimens subjected to a constant amplitude, periodic forcing function in air at room temperature.
The storage medium should generally be removed before testing using appropriate solvents, if necessary, without adverse effects upon the life of the specimens. Surfaces intended to be parallel and straight should be in a manner consistent with 8.
However, regardless of the nature of the forcing function, it should be reported sine, ramp, saw tooth, etc. Unmanned Maritime Vehicle Standards. However, the design should meet certain general criteria outlined below: The reduced section length should be greater than three times the minimum test section diameter. The test section length should be approximately two to three times the test section diameter.

Dimensional analysis and inspection should be conducted in a manner that will not visibly mark, scratch, gouge, score, or alter the surface of the specimen.
Every effort should be made to prevent the occurrence of misalignment, either due to twist rotation of the gripsor to a displacement in their axes of symmetry.
