The property KIc GIc determined by ASTM D characterizes the resistance of a material to fracture in a neutral asym in the presence of a sharp crack under severe tensile constraint, such that the state of stress near the crack front approaches plane strain, and the crack-tip plastic or non-linear viscoelastic region is small compared with the crack size and specimen dimensions in the constraint direction.

This standard and ISO address the axtm subject matter, but differ in technical content. Specimen thickness must be sufficient to ensure this stress state. However, certain conditions and specifications not covered in Test Method Ebut important for plastics, are included.
