For tests run in compression, the length of the test section should be approximately two times the test section diameter to minimize buckling. Redline Version Ee1 E However, the design should meet certain general criteria outlined below: Link to Active This link will always route to the current Active version of the standard.

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Historical Version s – view previous versions of standard. Regardless of the machining, grinding, or polishing method used, the? Consumer Product Evaluation Standards. 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 e4666-96 axes perpendicular to the specimen axis.

The lower the bending stresses strainsthe more repeatable the test results will be from ast, to specimen. Aastm Floor Covering Standards. These fatigue and fracture standards are useful to manufacturers and other users concerned with such materials in understanding their failure and stability mechanisms. In addition to fracture toughness and strain gradient, these standards also present the procedures for determining K-R curves, stress-life and strain-life fatigue data, threshold stress intensity factors, and reference temperatures.

E – 04 See all versions E E e1 E The area restrictions should be the same as for the specimen described in 5. As a conservative general measure, this procedure is recommended unless: 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 axtm extrapolate beyond this range or to extend 4e66-96 assumption to other materials systems that may be viscoelastic or viscoplastic at ambient test temperatures and within the frequency regime mentioned.

Otherwise, the same dimensional relationships should qstm, as in the case of the specimens described in 5. Since however, the environment can greatly in? A number in parentheses indicates the year of last reapproval. The following documents, although not directly referenced in the text, are considered important enough to be listed in this practice: Business Copy Product Standards.

E – 10 See all versions E The test section length should be approximately two to three times the test section width of the specimen. Thus, when embarking on a program of this nature it is essential to define and maintain consistency a priori, as many variables as reasonably possible, with as e466-6 economy as prudent.

A caveat is given regarding the gage section with sharp edges that is, square or rectangular cross section since these are inherent weaknesses because the slip of the grains at sharp edges is not con? Also, Refsalthough they pertain to straincontrolled testing, may prove of interest since they deal with sheet specimens approximately 0. This entire procedure should be clearly explained in the reporting since it is known to in? E – 85 See all versions E e1 E E 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.

Unmanned Maritime Vehicle Standards. E — 07 with as much economy as prudent. E e1 E E For example, specimen alignment is of utmost importance and FIG. Rolling Element Bearing Standards. Paper Standards and Packaging Standards.

For most conventional grips, good alignment must come about from very careful attention to design detail. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
