ASTM E390 Reference Radiographs for Steel Castings
The ASTM E390 standard specifies the procedures and requirements for producing reference radiographs of steel castings. These radiographs serve as benchmarks against which actual castings can be compared during inspections to ensure compliance with design specifications and quality standards. This service is critical in ensuring that manufacturers adhere to strict quality control measures, particularly in sectors where precision and reliability are paramount.
The ASTM E390 radiographs are used extensively in industries such as aerospace, automotive, and heavy machinery manufacturing. In these sectors, the integrity of steel castings can significantly impact safety and performance. By providing a standardized reference point, this service helps to eliminate variability and ensure consistency across production batches.
When creating ASTM E390 radiographs, it is essential to follow precise procedures to ensure accuracy and reliability. The process begins with selecting the appropriate radiation source and exposure settings that will produce clear images of the casting's internal structure. Once the initial radiograph is produced, it undergoes a rigorous review process to ensure that it meets all specified criteria.
The production of ASTM E390 reference radiographs involves several critical steps:
- Selection of the appropriate radiation source and exposure settings
- Careful preparation of the casting for imaging
- Exposure of the casting to produce the initial radiograph
- Review and approval by qualified personnel
- Storage and archiving for future reference
The use of ASTM E390 reference radiographs is not limited to steel castings alone but can be applied to other materials as well. However, the specific criteria and procedures may vary depending on the material being tested.
The primary goal of this service is to provide a reliable means of quality control that can be consistently reproduced across different facilities and production runs. This ensures that all parties involved in the manufacturing process are working from the same reference point, thereby enhancing confidence in the final product's integrity and reliability.

The use of ASTM E390 radiographs in quality control processes is essential for maintaining high standards in manufacturing. By providing a standardized benchmark, this service helps to ensure that all castings meet the required specifications and are free from defects.
Scope and Methodology
| Step | Description |
|---|---|
| Select Radiation Source | Precision selection of the radiation source to ensure clarity in imaging |
| Prepare Casting | Careful preparation of the casting for optimal exposure |
| Exposure | Production of initial radiograph using selected settings |
| Review and Approval | Thorough review by qualified personnel to ensure compliance with ASTM E390 standards |
| Storage | Absolute storage for future reference and comparison |
The production of ASTM E390 radiographs involves a series of meticulous steps designed to produce high-quality images that can be used as benchmarks. The selection of the radiation source is critical, as it directly impacts the clarity and detail of the resulting image.
Once the appropriate radiation source has been selected, careful preparation of the casting is necessary. This includes ensuring that the casting is clean, free from any contaminants or imperfections that could affect the quality of the radiograph.
The exposure step involves producing an initial radiograph using the selected settings. It is important to ensure that the exposure time and intensity are appropriate for the size and type of the casting being imaged.
After the initial radiograph has been produced, it undergoes a rigorous review process. This ensures that the radiograph meets all specified criteria and standards as outlined in ASTM E390.
The final step is storage and archiving for future reference and comparison. By storing these radiographs in a secure location, they can be easily accessed when needed to ensure consistency across different production runs.
