ASTM E155 Reference Radiographs for Investment Castings
The ASTM E155 standard provides reference radiographs that serve as benchmarks for inspecting investment castings. These reference images help ensure consistent and reliable defect detection, which is critical in the metallurgy and material testing sector. By adhering to this standard, quality managers can maintain high standards of product integrity, ensuring that defects are accurately identified and minimized.
The ASTM E155 radiographs are used during the inspection process as a comparison against the actual castings being examined. This allows for more precise defect identification and reduces the likelihood of false positives or negatives. The standard defines specific conditions under which these reference images should be captured, including exposure settings, film type, and processing techniques.
The primary purpose of using ASTM E155 is to provide a consistent benchmark against which inspection results can be compared. This ensures that all parties involved in the casting process are working towards the same standard. By using these reference radiographs, quality managers can ensure that any deviations from expected standards are immediately apparent.
Investment castings are highly complex and intricate parts used across various industries such as aerospace, automotive, and manufacturing. The precision required in their production necessitates rigorous inspection methods like those outlined in ASTM E155. This standard not only helps maintain consistent quality but also enhances safety by ensuring that any potential defects are identified early in the process.
The use of ASTM E155 reference radiographs is particularly important for investment castings due to their complexity and critical nature. These parts often bear significant loads and stresses, making them prone to even minor flaws which could lead to catastrophic failures if left undetected. By using these reference images as a baseline for inspection, quality managers can ensure that any such defects are caught early in the manufacturing process.
In addition to serving as a benchmark for defect detection, ASTM E155 also helps in training inspectors and technicians. The standardized approach provided by this standard ensures that all individuals involved in the inspection process follow the same procedures, leading to more consistent results. This is especially beneficial when dealing with complex parts like investment castings where slight variations can have significant impacts on performance.
The ASTM E155 reference radiographs are an essential tool for ensuring high-quality investment castings. By providing a consistent benchmark against which inspection results can be compared, this standard helps maintain strict quality control measures and enhances safety by identifying potential defects early in the manufacturing process.
Why It Matters
The importance of ASTM E155 reference radiographs cannot be overstated. These images serve as a critical tool for inspecting investment castings, ensuring that any defects or imperfections are accurately identified and addressed early in the manufacturing process.
Investment castings are used across various industries due to their high precision and intricate design capabilities.

Applied Standards
| Standard | Description |
|---|---|
| ASTM E155-09(2017) | This standard provides reference radiographs that serve as benchmarks for inspecting investment castings. It defines specific conditions under which these reference images should be captured, including exposure settings, film type, and processing techniques. |
| ISO 13469-2 | It outlines the requirements for radiographic examination of materials used in nuclear power plants. While not directly related to investment castings, it provides a comprehensive framework that can be adapted for use with ASTM E155. |
The application of these standards ensures consistent and reliable defect detection during the inspection process. The precise exposure settings, film types, and processing techniques specified in ASTM E155 help to minimize variability, ensuring accurate results across different inspections.
For example, when using a specific type of radiographic film, it is crucial that all inspectors follow the exact same procedure so that the resulting images are as consistent as possible. This consistency allows for easier comparison between actual castings and the reference radiographs provided by ASTM E155.
