ASTM E2192

ASTM E2192 is a technical guide focused on planar flaw height sizing by ultrasonics, offering a structured approach for evaluating flaw dimensions with ultrasonic methods. It is designed to support consistent measurement practices where planar discontinuities must be characterized accurately for engineering, inspection, and quality decisions. By clarifying how ultrasonic sizing may be applied, the standard helps users improve reliability, compare results more consistently, and support informed acceptance or further evaluation of inspected components.

ASTM E2192 standard overview

The Standard Guide for Planar Flaw Height Sizing by Ultrasonics provides guidance for estimating the height of planar flaws using ultrasonic techniques. As an ASTM standard, it serves as a technical reference for inspection workflows that need repeatable sizing practices rather than general defect detection alone. ASTM E2192 is relevant when the height of a planar indication must be assessed in a controlled and defensible way, supporting more consistent interpretation across personnel, equipment setups, and inspection programs.

Where is ASTM E2192 used?

This standard is commonly used in ultrasonic examination programs where planar flaws need height sizing as part of nondestructive testing. It may be applied in inspection environments that rely on ultrasonic probes, instrumentation, and established scan procedures to evaluate indications in manufactured or in-service items. ASTM E2192 is especially useful when teams need a documented guide for sizing decisions during quality control, engineering assessment, or condition evaluation workflows tied to ultrasonic inspection.

Practical importance of ASTM E2192

ASTM E2192 matters because accurate flaw sizing can affect compliance decisions, risk evaluation, and product acceptance. Using a common guide helps reduce variability in how planar flaw height is estimated, which is important when different technicians, systems, or sites are involved. It also supports procurement and specification work by giving buyers and suppliers a shared technical reference. For organizations that depend on ultrasonic testing, the standard can improve consistency and confidence in inspection results.
