Revision of E1820-22 Standard Test Method for Measurement of Fracture Toughness


An alternative method for measuring crack size, the Area Average Method, is proposed for inclusion in ASTM E1820. This method has been shown to provide equivalent accuracy and only slightly stricter crack curvature allowance with respect to the well-established 9-Point Average Method. Results of two published studies comparing the two approaches were presented during the E08.07.05 meetings of November 2021 and May 2022.
