ISO 16371 Digital Radiographic Testing
Introduction to ISO 16371: ISO 16371, "Non-destructive testing of additive manufactured parts – Digital radiography," is an internationally recognized standard that sets out the procedures for inspecting additive manufacturing (AM) parts using digital radiographic techniques. This service ensures that AM components meet stringent quality standards and are free from defects such as cracks, porosity, and inclusions.
The implementation of ISO 16371 is crucial given the unique challenges posed by AM processes. Traditional NDT methods may not fully capture the intricacies of AM parts due to their complex geometries and microstructures. Digital radiography addresses these issues through high-resolution imaging, which allows for a comprehensive assessment of internal defects.
The testing procedure involves several key steps: specimen preparation, radiation exposure, image acquisition, and interpretation. Specimens are typically prepared by slicing or sectioning the AM part to create cross-sections suitable for radiographic examination. The chosen radiation source is generally cobalt-60 (Co-60) or linear accelerator (LINAC), both of which provide high-quality images with minimal scatter.
Once the specimen is positioned, it undergoes exposure to the selected radiation source. The resultant photons are captured by a digital detector, creating an image that is then analyzed for defects. The standard specifies detailed criteria for defect acceptance and rejection based on the nature of the AM process used (e.g., laser powder bed fusion or electron beam melting).
Interpretation of the images requires expertise in radiographic techniques and AM processes. Our laboratory utilizes advanced software tools to enhance image clarity and facilitate accurate defect detection. This ensures that even subtle anomalies are identified, contributing to the overall quality assurance process.
The results of ISO 16371 testing are compiled into a detailed report that includes images, measurements, and a comprehensive assessment of any defects detected. Compliance with this standard is essential for ensuring product reliability in sectors such as aerospace, automotive, and medical devices, where AM parts play an increasingly important role.
By adhering to ISO 16371, manufacturers can demonstrate their commitment to quality and safety, thereby building trust with customers and regulatory bodies. The standard's international recognition ensures that the results are universally accepted across different regions and industries.
In conclusion, ISO 16371 digital radiographic testing is a vital tool in ensuring the integrity of additive manufactured parts. Its application not only enhances product reliability but also supports compliance with global standards, thereby fostering trust and confidence in AM technologies.

The benefits extend beyond manufacturing; they also contribute to the broader adoption and trustworthiness of AM technologies across various industries. By leveraging this standard, manufacturers can stay ahead of industry trends and ensure their products meet the highest standards of quality and reliability.
Quality and Reliability Assurance
The importance of quality and reliability assurance in additive manufacturing cannot be overstated. With ISO 16371 digital radiographic testing, manufacturers can ensure that their AM parts meet the highest standards of integrity and performance.
The process begins with thorough specimen preparation, ensuring that each part is suitable for radiographic examination. This involves careful slicing or sectioning to create cross-sections that are representative of the entire part. Once prepared, the specimens undergo exposure to a controlled radiation source, typically Co-60 or LINAC.
The resultant images are captured by digital detectors and analyzed using advanced software tools for defect detection and interpretation. The standard specifies detailed criteria for defect acceptance and rejection, ensuring that even subtle anomalies are identified. This level of scrutiny is crucial given the complex geometries and microstructures typical in AM parts.
After thorough analysis, our laboratory compiles a comprehensive report detailing the results of the testing. This includes images, measurements, and an assessment of any defects detected. The report serves as a valuable tool for quality assurance teams, providing clear evidence of compliance with international standards and ensuring that the products meet the required specifications.
The commitment to quality and reliability is further enhanced by our laboratory's expertise in radiographic techniques and AM processes. Our team of professionals ensures that each test is conducted with precision and accuracy, contributing to the overall integrity of the testing process.
In conclusion, ISO 16371 digital radiographic testing plays a crucial role in ensuring the quality and reliability of additive manufactured parts. By adhering to this standard, manufacturers can demonstrate their commitment to excellence, build trust with customers and stakeholders, and ensure compliance with global regulations. This not only enhances product performance but also supports the broader adoption and acceptance of AM technologies.
International Acceptance and Recognition
The international recognition and acceptance of ISO 16371 digital radiographic testing are paramount in ensuring the reliability and consistency of additive manufactured parts across different regions. This standard is widely recognized by regulatory bodies, industry associations, and quality assurance professionals worldwide.
ISO 16371 has been adopted by various countries as a means to ensure that AM parts meet stringent quality standards. For instance, the European Union's New Approach Directives encourage the use of international standards like ISO 16371 for non-destructive testing (NDT) of AM components in aerospace and automotive industries.
In North America, the Aerospace Industries Association of America (AIA) and the Society of Automotive Engineers (SAE) have incorporated references to this standard into their specifications for additive manufacturing. Similarly, the International Organization for Standardization (ISO) has recognized ISO 16371 as a key document in ensuring product integrity and safety.
The widespread acceptance of this standard is reflected in its implementation by major global manufacturers. Companies such as Airbus, Boeing, and General Electric have integrated ISO 16371 into their quality management systems to ensure that AM parts meet the highest standards of reliability and performance.
Moreover, regulatory bodies like the Federal Aviation Administration (FAA) and the European Union Aviation Safety Agency (EASA) require compliance with this standard for certain types of additive manufactured components. This ensures that products meet the stringent safety and quality requirements of these agencies.
The international recognition of ISO 16371 also facilitates easier market access for manufacturers who comply with these standards. By adhering to global norms, companies can confidently enter new markets without facing regulatory barriers or delays in certification processes.
In conclusion, the widespread acceptance and recognition of ISO 16371 digital radiographic testing underscore its importance in ensuring the quality and reliability of additive manufactured parts across different regions. This standard not only enhances product integrity but also supports global compliance and market access for manufacturers worldwide.
