The storage medium should generally be removed before testing using appropriate solvents, if necessary, without adverse effects upon the life of the specimens. E — 07 with as much economy as prudent. Oxygen Enriched Atmospheres Standards.

As a cautionary note, should localized yielding occur, signi? Threaded end specimens may prove difficult to align and failure often initiates at these stress concentrations when testing in the life regime of interest in this practice. Current edition approved Nov. Specimens should be cleaned prior to testing with solvent s non-injurious and non-detrimental to the zstm properties of the material in order to remove any surface oil?

E E e1 E All material variables, testing information, and procedures used should be reported so that correlation and reproducibility of astn may be attempted in a fashion that is considered reasonably good current test practice. It is beyond the scope of Practice E to extrapolate beyond this range or to extend this assumption to other materials systems that may be viscoelastic or viscoplastic at ambient test temperatures and within the frequency regime mentioned.

Appendix X1 presents an example of a machining procedure that has been employed on some metals in an attempt to minimize the variability of machining and heat treatment upon fatigue life. The value of 1. 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.

Regardless of the machining, grinding, or astj method used, the? To do so would require the control or balance of what are often deemed nuisance variables; for example, hardness, cleanliness, grain size, composition, directionality, surface residual stress, surface?

In view of this fact, the method of preparation should be agreed upon prior to the beginning of the test program by both the originator and the user of the fatigue data to be generated.

In view of this, no maximum ratio of area grip to test section should apply. The following documents, although not directly referenced in the text, are considered important enough to be listed in this practice: Thus, when embarking on a program of this nature it is essential to de?

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.

This practice is not intended for application in axial fatigue tests of components or parts. The test forces should be monitored continuously in the early stage of the test and periodically, thereafter, to ensure that the desired force cycle is maintained. However, regardless of the nature of the forcing function, it should be reported sine, ramp, saw tooth, etc.
