Tensile Properties of Film - ISO 527-1,-3
For film and sheet materials with a thickness up to 1 mm. For materials with a thickness greater than 1 mm ISO 527-1,-2 should be used.
|Tensile Modulus||Slope of the stress-strain curve between two specified strains (ε1=0.0005 and ε2=0.0025)|
|Tensile Strain at Break||Tensile strain corresponding to the point of rupture.|
|Tensile Strain at Yield||Tensile strain corresponding to the yield point.|
|Tensile Strength||Maximum tensile stress sustained by the specimen during a test.|
|Tensile Stress at Break||Tensile stress at the point of rupture.|
|Tensile Stress at Yield||Tensile stress at which an increase in strain occurs without an increase in stress (yield point).|
Two sets of specimens are tested for anisotropic materials, the first set parallel to the direction of polymer orientation (MD - machine direction) and the second set perpendicular to the direction of polymer orientation (TD - transverse direction).
|4||Flexible thermoplastic sheet|
|5||Very high strain at break materials|
