SUMMARY
This discussion focuses on sourcing laboratory samples for mechanical testing, specifically Charpy impact test samples and standard tensile test samples. Reliable sources include Sigma-Aldrich for calibration samples and Anand Testing for Charpy V-Notch reference test pieces. For training purposes, users can create their own specimens using threaded rods and flat stock. The discussion emphasizes the importance of low surface stress machining for tensile specimens and suggests close collaboration with machinists to ensure quality.
