ASTM E2375-22 PDF

Overview

ASTM E2375-22: Standard Practice for Ultrasonic Testing of Wrought Products is a key international standard developed by ASTM International. This standard specifies the minimum requirements and recommended practices for conducting ultrasonic testing on wrought metals such as forged, rolled, or machined parts. Ultrasonic testing (UT) is a widely-used nondestructive testing (NDT) technique that enables professionals to detect internal defects and assess the quality and integrity of metallic products without causing damage.

ASTM E2375-22 is applicable to wrought metal products with thickness or cross-sections of 0.250 inches (6.35 mm) or greater. It provides a systematic approach for selecting ultrasonic examination methods, acceptance criteria, reference standards, and necessary qualifications for personnel performing UT. Originally developed to replace MIL-STD-2154, this standard continues to serve industries where product reliability and safety are paramount.

Key Topics

• Scope and Applicability

  • Applies to wrought metals and products ≥ 0.250 in. (6.35 mm) thick.
  • Covers examination of aluminum alloys, magnesium alloys, titanium, and various steels and specialty alloys.

• Ultrasonic Examination Classes

  • Defines five ultrasonic acceptance classes, enabling tailored criteria for different product applications.
  • Acceptance criteria are specified by engineering drawings or contract documents.

• Personnel Qualification

  • Requires examiners to be qualified and certified according to internationally recognized standards such as ANSI/ASNT-CP-189, NAS-410, or SNT-TC-1A.

• Written Examination Procedures

  • Mandates detailed documentation of procedures, including equipment, scanning plans, reference standards, and acceptance levels.
  • Procedures must be approved by appropriately qualified Level III personnel.

• Reference Standards and Blocks

  • Provides guidance on fabricating and certifying reference blocks, including requirements for material type, size, surface finish, and calibration.

• Equipment and Couplants

  • Describes requirements for ultrasonic examination equipment, including performance checks, calibration, and maintenance.
  • Guidance on couplants compatible with test materials and surface conditions is included.

Applications

ASTM E2375-22 is essential in industries where the integrity of wrought metal components is critical. Key applications include:

• Aerospace and Defense: Testing of structural aircraft components, turbine engine parts, and machined elements for critical roles.
• Automotive: Verification of rolled or forged elements such as axles, connecting rods, and chassis components.
• Energy Sector: Inspection of pressure vessels, piping, and safety-critical parts in power generation and oil & gas.
• Manufacturing: Quality assurance in the production of bars, rods, tubes, and plates for further fabrication.

By following ASTM E2375-22, organizations can assure compliance with contract and regulatory requirements, reduce the risk of in-service failures, and ensure public safety.
