ASTM E802

ASTM E802 is a reference radiograph standard for gray iron castings up to 412 in. (114 mm) in thickness, providing a common visual basis for evaluating casting conditions. It helps inspectors, foundries, and buyers compare radiographic images against established reference examples when reviewing gray iron castings. By supporting more consistent interpretation, this ASTM standard can improve communication, reduce ambiguity, and strengthen quality control decisions in casting inspection.

ASTM E802 standard overview

ASTM E802 provides standard reference radiographs intended for gray iron castings within the thickness range identified in the official title. The document is used as a technical comparison tool rather than a design specification, helping users assess radiographic indications against recognized examples. In practice, this supports more uniform evaluation of casting quality and a clearer basis for acceptance discussions. ASTM E802 is especially relevant where radiographic inspection is part of routine foundry or procurement requirements.

Where is ASTM E802 used?

This standard is commonly used in foundries, inspection departments, and purchasing or quality assurance workflows that involve gray iron castings. It is most useful wherever radiographic examination is applied to compare actual casting images with reference radiographs for a defined thickness range. ASTM E802 may also support supplier qualification and buyer-seller agreements when castings must be evaluated against the same visual benchmark. That makes it a practical reference in inspection and acceptance activities.

Practical importance of ASTM E802

ASTM E802 matters because it helps create a consistent language for evaluating gray iron casting radiographs. When teams use the same reference images, they can reduce interpretation differences and improve confidence in inspection outcomes. This can support compliance efforts, product evaluation, and procurement decisions by making acceptance checks more repeatable. For organizations that rely on radiographic quality control, the standard offers a reliable benchmark for comparing casting conditions.
