As applicable.
The listed mechanical property symbols should be followed by one of the following additional symbols for wrought alloys, not castings.
- L — Longitudinal direction; parallel to the principal direction of flow in a worked metal.
- T — Transverse direction; perpendicular to the principal direction of flow in a worked metal; may be further defined as LT or ST.
- LT — Long-transverse direction; the transverse direction having the largest dimension, often called the “width” direction.
- ST — Short-transverse direction; the transverse direction having the smallest dimension, often called the “thickness” direction.
Values of and should indicate the appropriate edge distance/hole diameter (e/D) ratio. Design properties are presented for two such ratios: e/D = 1.5 and e/D = 2.0.
Data for use in establishing these properties should be based on ASTM standard testing practices. The test practice and any deviations therefrom should be reported when submitting proposals to the MIL-HDBK-5 Coordination Group for consideration.
