The following documents, although not directly referenced in the text, are considered important enough to be listed in this practice: Business Copy Product Standards. The area restrictions should be the same as for the specimen described in 5.
Resilient Floor Covering Standards. For rectangular cross section specimens, alignment should be checked by placing longitudinal strain gages on either side of the trial specimen at the minimum width location. Search and Rescue Operations Standards.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are e4669-6 their own responsibility.
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. Redline Version Ee1 E Electrical Standards and Magnetic Conductor Standards. 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.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. The size of the gripped end relative to the gage section, and the blend radius from gage section into the grip section, may cause premature failure particularly if fretting occurs in the grip section or if the radius is too small.
Fillet undercutting can be readily determined by inspection. The trial specimen should be rotated e66-96 its longitudinal axis, installed and checked in both orientations within the? E — 07 with as much economy as prudent.
Otherwise, the same dimensional relationships should apply, as in the case of the specimens described in 5. For most conventional grips, good alignment must come about from very careful attention to design detail. No further reproductions authorized. The results may also be used as a guide for the selection of metallic materials for service under conditions of repeated direct stress. Oxygen Enriched Atmospheres Standards. No circumferential machining should be evident when viewed at approximately magni?
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. Obvious abnormalities, such as cracks, machining marks, gouges, undercuts, and so forth, are not acceptable.
This is a particular danger in soft materials wherein material can be smeared over tool marks, thereby creating a aastm undesirable in?
E – 03 See all versions E E E In the case of surfaces that are not smooth, due 4e66-96 the fact that some surface treatment or condition is being studied, the dimensions should be measured as above and the average, maximum, and minimum values reported. However, regardless of the nature of the forcing function, it should be reported sine, ramp, saw tooth, etc. Readers are referred to Ref 1 should r466-96 occur.
ASTM’s fatigue and fracture standards provide the appropriate procedures for carrying out fatigue, fracture, and other related tests on specified materials. The trial test specimen should be turned about its axis, installed, and checked for each of four orientations within the? 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.
