SAE AMS3045G-2024 PDF

Full title and description

SAE AMS3045G — Magnetic Particles, Fluorescent Wet Method, Oil Vehicle, Ready-to-Use. Material specification defining the required properties, performance and delivery of fluorescent magnetic-particle detection media supplied as a mixed, ready-to-use suspension in an odorless inspection-oil vehicle for fluorescent wet magnetic-particle inspection (MPI).

Abstract

This specification establishes physical, chemical and performance requirements, test methods, marking and packaging for fluorescent magnetic-particle suspensions supplied in an oil vehicle and intended for use with the fluorescent wet (wet method) magnetic-particle inspection technique. The document defines the detection-media characteristics needed to ensure reliable indication of surface and near-surface discontinuities in ferromagnetic parts.

Scope

This specification covers fluorescent magnetic-particle detection media in the form of a mixed, ready-to-use suspension in an odorless inspection oil vehicle intended for wet-method magnetic-particle inspection. It defines required media performance (sensitivity/indication characteristics), physical and chemical properties, packaging, labeling, and test procedures for verifying media suitability. It does not prescribe equipment details for magnetization or acceptance criteria for inspected parts beyond requirements for the detection media itself (product-performance and test methods are the primary focus).

Key topics and requirements

• Definition of fluorescent magnetic-particle suspension composition and carrier (odorless inspection oil) requirements.
• Performance and sensitivity criteria for detection media — detectable flaw sizes and visibility under specified UV / viewing conditions.
• Physical property limits (particle size distribution, color/fluorescence, suspension stability, viscosity and sedimentation).
• Test methods and sample procedures to verify media performance prior to shipment and on receipt (bench tests and acceptance checks).
• Packaging, labeling, shelf-life/storage instructions, and handling/health-and-safety notes for inspection media.
• Marking and documentation requirements for traceability and procurement compliance.

Typical use and users

Used by nondestructive testing (NDT) laboratories, aerospace and defense inspection teams, OEM and subcontractor quality control, specialty inspection shops and procurement/specification engineers who require a qualified fluorescent wet-method magnetic-particle detection media for routine and critical MPI tasks. Typical applications include inspection of ferromagnetic components, welds and assemblies where fluorescent wet MPI is the chosen method for surface and near-surface discontinuity detection.

Related standards

Relevant complementary standards and documents include international and industry-level MPI standards and parts addressing general principles, detection media and equipment, for example ISO 9934 series (magnetic particle testing — general principles and detection media) and ISO 17638 (magnetic particle testing of welds). AMS3045 historical revisions (A–F) precede this revision G and may be referenced for traceability.

FAQ

Q: What is this standard?

A: SAE AMS3045G is a material specification from SAE International that defines fluorescent magnetic-particle detection media supplied as a ready-to-use suspension in an odorless oil vehicle for fluorescent wet magnetic-particle inspection.

Q: What does it cover?

A: It covers the required composition, physical and performance characteristics, test methods, packaging, labeling and handling instructions for fluorescent oil-based MPI detection media; the intent is to ensure consistent, reliable indications when the media are used in fluorescent wet MPI.

Q: Who typically uses it?

A: NDT technicians and laboratories, aerospace/defense quality and inspection personnel, OEMs and subcontractors specifying or purchasing fluorescent wet MPI media, and procurement/engineering teams who reference AMS product specifications.

Q: Is it current or superseded?

A: Current — AMS3045G is the Revision G of the AMS3045 series and was published (revised) on 16 January 2024; it supersedes earlier revisions (for example AMS3045F).

Q: Is it part of a series?

A: Yes — AMS3045 is a longstanding SAE material specification that has undergone multiple revisions (A, B, C, D, E, F prior to G). It also sits within the broader family of MPI-related documents (ISO and other AMS/MIL specifications) that cover test methods, equipment and acceptance practices.
