ASTM International Key Features and Plates The reference photographs are organized into four large charts
(referred to as Plates) that categorize discontinuities by type and severity: GlobalSpec Plate 1: Linear Discontinuities – Covers cracks and other elongated surface flaws. Plate 2: Shrinkage and Inclusions
– Displays internal voids or trapped non-metallic materials.
Plate 3: Internal Chills and Unfused Chaplets, Porosity, and Welds
– Focuses on casting-specific artifacts and welding-related indications. Plate 4: False Indications and Magnetic Anomalies
– Helps inspectors distinguish real defects from non-relevant magnetic field behaviors. GlobalSpec Available Formats You can obtain these reference materials through the ASTM International official site or authorized distributors in the following formats:
: Contains the standard text along with descriptions and explanatory notes for the 31 photographs. Hard Copy (Adjunct)
: 31 black-and-white prints mounted on 8.5 x 11-inch cards, specifically designed for side-by-side comparison with actual castings. Digital Image Set
: High-resolution JPEG files suitable for viewing on computers or printing. Standard Usage and Classification : These photographs act as a visual baseline for acceptance criteria agreed upon between manufacturers and purchasers.
: Inspectors compare the magnetic particle indications observed on a casting to the graded photographs in the standard to determine the degree of the discontinuity.

ASTM E125 (Standard Reference Photographs for Magnetic Particle Indications on Ferrous Castings) is a technical standard used to classify discontinuities in steel and other ferrous castings detected via magnetic particle examination. The standard provides a visual comparison tool to ensure consistent interpretation of inspection results across the industry. Overview of ASTM E125
Purpose: To assist in identifying and classifying types and degrees of surface and near-surface discontinuities (like cracks or inclusions) on castings.
Methodology: It focuses on indications revealed by the dry powder magnetic particle method.
Scope: Covers 31 reference photographs across eight distinct categories of discontinuities. Discontinuity Classifications
The standard designates types of discontinuities using Roman numerals I through VIII: Type I: Linear Discontinuities (Hot tears and cracks). Type II: Shrinkage. Type III: Inclusions. Type IV: Internal Chills and Chaplets. Type V: Porosity. Type VI: Weld Discontinuities. Type VII: False Indications. Type VIII: Magnetic Anomalies. Formats and Availability
The standard is actively maintained by ASTM International, with the latest reapproval occurring in 2023 (ASTM E125-63R23). It is available in several formats:
PDF Document: Typically a 3-page document containing the classification text, although it often requires separate physical charts for high-resolution comparison.
Reference Charts: Available from ASTM as four large charts (Order ADJE0125) specifically arranged for each type of discontinuity.
Official Sources: You can purchase or access official copies through the ASTM International website or authorized distributors like Accuris Standards Store and BSB Edge. Summary of Document Data

The standard organizes defects into eight distinct types, designated by Roman numerals I through VIII : Linear Discontinuities (such as cracks and hot tears). : Shrinkage. : Inclusions. : Internal Chills and Chaplets. : Porosity. : False Indications. : Magnetic Anomalies. Steel Founders’ Society of America Severity Levels and Interpretation Severity Degrees : Most discontinuity types are classified into five degrees of severity (1 being the least severe). However, Porosity (Type V) typically only features two examples. No Cross-Correlation
: It is important to note that severity degrees are not equivalent across different types; for example, a Degree 3 for Type I is not the same as a Degree 3 for Type II. Inspection Method
: The reference photos show indications created with specific parameters: a peak current of 600 to 800 A and prod spacing of 4 to 10 inches Steel Founders’ Society of America How to Access the Reference Photographs

ASTM E125 – Standard Reference Photographs for Inspection of Aluminum Alloy and Metal-Produced Castings (Note: While often associated with general casting inspection, users frequently conflate standards. ASTM E125 is specifically titled "Standard Reference Photographs for Inspection of Aluminum Alloy and Metal-Produced Castings", but it is widely referenced alongside visual inspection methods for various metals).
Correction/Clarification: It is important to distinguish between standards. If you are inspecting Steel Castings, the applicable standard for reference photographs is ASTM A802. However, many industry veterans and older documents historically refer to "E125" in the context of general visual inspection or specific customer specifications that adopt E125 for non-ferrous or specific alloy checks.
For the purpose of this article, we will focus on the structure of ASTM E125 (for Aluminum/Metal) and how it functions as a visual comparator, a logic that applies across various casting inspection standards.
ASTM E125 is a standard developed by ASTM International (formerly the American Society for Testing and Materials). It provides a set of visual reference photographs used to classify the appearance of indications found during magnetic particle inspection.
Magnetic particle inspection is a method used to detect surface and near-surface discontinuities in ferromagnetic materials. However, simply finding an indication isn't enough; an inspector must determine if it is relevant (a defect) or non-relevant (such as magnetic writing or a change in section).
The photographs are graded on a severity scale, typically Class 1 (Lightest) to Class 6 (Most Severe).
If you acquire the official standard, here is the best workflow for using the reference photographs:
ASTM E125 - Standard Reference Photographs for Magnetic Particle Indications on Ferrous Castings is a critical standard published by ASTM International. It specifically covers the types and degrees of discontinuities that can be revealed by the magnetic particle inspection method on ferrous castings.
Unlike general NDT standards, ASTM E125 is unique because it relies heavily on visual comparison. The standard does not just describe defects in words; it provides actual photographic reproductions of castings showing various levels of surface and subsurface discontinuities.
Older PDFs (e.g., 1963, 1986, 2002) are circulating online. Do not rely on them. ASTM E125 was significantly updated in 2018 and reaffirmed in 2023.
