SNT-TC-1A: NDT Personnel Qualification and Certification Requirements
SNT-TC-1A is ASNT's recommended practice for employer NDT certification: 2024 UT, MT and PT hours, exams, vision, recertification, and CP-189 compared.
Head Checks in Rail: Causes, Progression, and When They Become Dangerous
Head checks in rail are gauge corner cracks 2–5 mm apart that can hide detail fractures from UT. Crack depths, 213.113(d)(7), 213.237(h) and grinding.
Rolling Contact Fatigue in Rail: Causes, Types, and Inspection Methods
Rolling contact fatigue in rail causes head checks, shells and squats that can mask UT. How 213.113 and 213.237(h) apply, and how crack depth guides grinding.
Rail Shelling and Spalling: Surface Defects That Lead to Internal Failures
Rail shelling and spalling are different head defects. Shells start below the gauge corner, mask ultrasonic tests and seed detail fractures. How to verify.
Bolt Hole Cracks in Rail Joints: Inspection Methods and Prevention
Bolt hole cracks under 49 CFR 213.113: how they form at rail joints, how 45° and 0° UT finds them, remedial actions by crack length, and how to prevent them.
Detail Fracture in Rail: How It Develops and How UT Detects It
A detail fracture in rail is a progressive crack from shells or head checks (49 CFR 213.113). How it grows, how 70° UT finds it, and the remedial actions.
Horizontal Split Head: What It Is and How Ultrasonic Testing Finds It
A horizontal split head is an internal rail head defect defined in 49 CFR 213.113. How it forms, how 0° UT finds it, and the remedial action for each length.
