ASTM E399 Plane-Strain Fracture Toughness Testing: Laboratory Testing Services
The ASTM E399 plane-strain fracture toughness testing is a widely accepted laboratory test for determining the resistance of materials to crack propagation. This test is governed by various international and national standards, including ISO 15780, EN 13724, TSE 1088, and ASTM E399.
International and National Standards
The International Organization for Standardization (ISO) publishes the ISO 15780 standard, which specifies the requirements for plane-strain fracture toughness testing. The European Committee for Standardization (CEN) has published the EN 13724 standard, which is equivalent to the ISO 15780 standard.
The Turkish Standards Institution (TSE) has published the TSE 1088 standard, which is based on the ASTM E399 standard. The American Society for Testing and Materials (ASTM) publishes the ASTM E399 standard, which specifies the requirements for plane-strain fracture toughness testing.
Standard Development Organizations
Standard development organizations play a crucial role in developing and updating standards. These organizations include:
These organizations work together to ensure that standards are consistent and aligned with international best practices.
Evolution of Standards
