SAE AMS-STD-2154E-2021 PDF

Full title and description

SAE AMS-STD-2154E:2021 — Inspection, Ultrasonic, Wrought Metals, Process for. This AMS (Aerospace Material Specification) provides uniform procedures and acceptance criteria for ultrasonic examination of wrought metals and wrought metal products to detect discontinuities and ensure material integrity in aerospace and related industries.

Abstract

Revision E (July 15, 2021) of AMS-STD-2154 consolidates prior revisions and clarifies ultrasonic inspection techniques, transducer sizing, test block inspection, distance-amplitude correction, and evaluation of discontinuities for wrought alloys. It supersedes Revision D and maintains requirements for personnel qualification, equipment, procedures and acceptance criteria for straight- and angle-beam ultrasonic inspections.

Scope

This standard applies to ultrasonic inspection of wrought metal products (including aluminum, titanium, magnesium and other wrought alloys) where ultrasonic methods are used to detect internal and near-surface discontinuities in forgings, bars, billets, plate and finished parts. It defines required equipment, reference standards/test blocks, calibration procedures, scanning techniques (straight and angle beam), evaluation criteria (including distance-amplitude correction), and personnel qualifications for acceptance-level inspections in aerospace and related industries.

Key topics and requirements

• Uniform ultrasonic inspection procedures for wrought metals (straight-beam and angle-beam techniques).
• Requirements for transducer selection and transducer size (revisions clarified in Revision E).
• Standard test block inspection and reference standards for calibration and verification.
• Distance‑amplitude correction (DAC) methodology and acceptance criteria for discontinuity evaluation.
• Personnel qualification, written procedures, recordkeeping and reporting requirements.
• Revision history and supersession rules (clarifies changes from prior revisions D, C, A and original issue).

Typical use and users

Used by aerospace manufacturers, NDT service providers, quality engineers, inspection technicians and maintenance organizations performing acceptance or in-process ultrasonic inspection of wrought metal parts and materials. Also used by procurement and quality assurance personnel for specifying inspection process requirements in purchase orders and maintenance instructions.

Related standards

Historical lineage and related documents include MIL-STD-2154 (original U.S. military standard) and earlier AMS-STD-2154 revisions (A, C, D). AMS-STD-2154E explicitly revises AMS-STD-2154D and references other AMS/NDT guidance and relevant calibration/test block standards used in ultrasonic inspection practice.
