The term tensile refers to the capability of the material being stretched or pulled out of shape.
Flat Tensiles are made from sheet, coil, plate, tubes, extrusions, or manufactured parts. Typically the standard size (.500”) is fabricated per ASTM E8, ASTM A370 (steel), or ASTM B557 (aluminum) from the raw material. Other specimen configurations (.750, .250”, DIN, JIS, 80mm, etc.) are utilized.


Some special tests required on flat tensiles include:

• R & N Value
• Poisson's Ratio
• K Value
• Young's Modulus (E)
• R Bar (Requires 3 specimens – Longitudinal (0º), Diagonal (45º), and Transverse (90º). A sheet or plate approximately 12" x 12" is desired.
