Procurement Recommendation

For verifying Charpy impact specimen notches, the CST-50 notch projector must provide high-resolution optical magnification (typically 20x–50x) with calibrated reticles to accurately measure U- or V-notch geometry per ISO 148 or ASTM E23 standards. Supplier selection should emphasize optical clarity, stable illumination, and ergonomic design for prolonged use in metallurgical labs. The system must allow precise comparison against standard templates to ensure notch depth, angle, and root radius compliance—critical for valid impact energy results. Choose vendors offering NIST-traceable calibration certificates, durable construction, and compatibility with both standard and sub-size specimens. Avoid units with poor focus stability or uncalibrated scales that introduce measurement uncertainty. Regular verification using certified reference notches is recommended. This equipment is essential for quality control in steel mills, aerospace material testing, and accredited laboratories where notch accuracy directly affects material certification and structural safety assessments.
