SUMMARY
The discussion centers on the differences between the ASTM E399-09 and BS 7448 methods for conducting fracture toughness tests. ASTM E399-09 is primarily used for determining the plane strain fracture toughness of metallic materials, while BS 7448 encompasses a broader range of materials and testing conditions. The conversation suggests that purchasing both standards for a side-by-side comparison is a practical approach to understanding their distinctions.
