I can provide tailored documentation templates or technical inspection steps based on your needs.

The standard is typically accompanied by four large reference charts (adjuncts): Plate 1: Linear discontinuities (e.g., hot tears, cracks). Plate 2: Shrinkage and inclusions. Plate 3: Internal chills, unfused chaplets, and porosity. Plate 4: False indications and magnetic anomalies. Classification System Astm E125 Reference Photographs Pdf

Porosity is caused by gas trapped in the metal during solidification. It displays as rounded, small, scattered indications across the casting surface. How to Use ASTM E125 Reference Photographs I can provide tailored documentation templates or technical

Utilizing unverified, low-resolution, or pirated PDF copies of ASTM E125 reference photographs during a quality audit can result in non-conformance findings. Certified quality systems (such as ASNT, ISO 9001, or Nadcap) require inspectors to use calibrated, authentic reference materials to ensure evaluation repeatability. Industrial Applications and Implementation Plate 3: Internal chills, unfused chaplets, and porosity

The standard divides discontinuities into distinct types, representing different kinds of casting defects. Each type includes various degrees of severity, with Grade 1 being the least severe and higher grades representing larger or more frequent indications. Type I: Linear Discontinuities

Degrees of severity for each applicable discontinuity type are denoted by numbers 1 through 5, increasing in severity. A critical point to remember is that there is no correlation between the degrees of different defect types. For example, a "Degree 3" of Type I (Linear) is equivalent to a "Degree 3" of Type II (Shrinkage).
