All material variables, testing information, and procedures used should be reported so that correlation and reproducibility of results may be attempted in a fashion that is considered reasonably good current test practice. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 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.

However, the design should meet certain general criteria outlined below: Road Standards and Paving Standards. Oxygen Enriched Atmospheres Standards. This practice is not intended for application in axial fatigue tests zstm components or parts. No circumferential machining should be evident when viewed at approximately magni?

In the case of surfaces that are not smooth, due to the fact that some surface treatment or condition is being studied, the dimensions should be measured as above and the average, maximum, and asfm values reported. Obvious abnormalities, such as cracks, machining marks, gouges, undercuts, and so forth, are not acceptable. Glass Standards and Ceramic Standards.

The varying stress amplitude, as determined by a suitable dynamic veri? 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 finish, and so forth.

The results may also be used as a guide for the selection of metallic materials for service under conditions of repeated direct stress. Current edition approved Nov.

One exception may be where these parameters are under study. The test section length should be approximately two to aztm times the test section width of the specimen.

The trial test specimen should be turned about its axis, installed, and checked for each of four orientations within the? Fatigue Standards and Fracture Standards ASTM’s fatigue and fracture standards provide the appropriate procedures asttm carrying out fatigue, fracture, and other related tests on specified materials.

This practice is limited to the ashm testing of axial unnotched and notched specimens subjected to a constant amplitude, periodic forcing function in air at room temperature.

E e1 E E 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. The acceptable ratio of the areas test section to grip section to ensure a test section failure is dependent on the specimen gripping method.

E – 03 See all versions E E E If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Asstm, at 4e66-96 address shown below.

This entire procedure should be clearly explained in the reporting since it is known to in? 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 test section length should be approximately two to three times the test section diameter.

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.
