Scope
This document provides guidelines for the four-point bending test used to evaluate the resistance of metals, including carbon steel, low-alloy steel, and corrosion-resistant alloys, to stress corrosion cracking. The document provides test guidance for both base metals and welds, including test procedures suitable for metals with and without a clear yield point in their stress-strain behavior. This document is a general method for the four-point bending test. Due to the diversity of service environments, relevant standards can be referenced as appropriate in specific circumstances.
