What is EN ISO 19232-1:2019?

EN ISO 19232-1:2019 is a technical standard that provides guidelines for the examination of

industrial X-ray films. It specifies the basic requirements for producing high-quality X-ray images

using film-based radiographic techniques. This standard is primarily used in non-destructive testing

(NDT) applications, where it plays a crucial role in ensuring the reliability and accuracy of

inspection results.

The Importance of Industrial X-ray Films

Industrial X-ray films are widely used in various industries to identify defects or anomalies in

different materials, including metals, welds, and engineered components. These films capture the

X-ray radiation transmitted through the object being inspected, producing a permanent image that

can be visually examined. The information obtained from these X-ray images helps in evaluating

the structural integrity and quality of the tested materials, thereby ensuring product safety and

performance.

Key Requirements of EN ISO 19232-1:2019

EN ISO 19232-1:2019 outlines specific requirements related to film processing, image quality,

interpretation criteria, and quality control measures. Let's take a closer look at some of these

key requirements:

Film Processing

The standard describes the necessary steps and parameters for film processing, including film

developing, fixing, washing, and drying. It provides guidelines for establishing and maintaining

consistent processing conditions to ensure desirable image quality and minimize processing

artifacts or defects.

Image Quality

EN ISO 19232-1:2019 emphasizes the need for high image quality in industrial radiography. It

establishes criteria for acceptable image density, contrast, resolution, and sensitivity. By

adhering to these requirements, industrial radiographers can obtain clear, detailed images that

facilitate accurate defect detection and characterization.

Interpretation Criteria

The standard also provides guidelines for interpreting X-ray films to identify and evaluate

defects accurately. It defines various types of discontinuities or indications that may be present

in the images, along with criteria for assessing their severity and impact on the material's

performance. Interpreting X-ray images requires expertise and experience to ensure reliable results.

Quality Control Measures

EN ISO 19232-1:2019 includes provisions for establishing effective quality control measures

throughout the entire radiographic process. This involves regular testing and monitoring of X-ray

equipment, film processing chemicals, and film characteristics. By implementing these measures,

organizations can maintain consistency and reliability in their industrial radiographic inspections.

Conclusion

EN ISO 19232-1:2019 plays a crucial role in ensuring high-quality X-ray images in non-destructive

testing applications. By following the guidelines provided in this technical standard, industrial

radiographers can obtain consistent and reliable results, leading to enhanced product safety and

performance. Adhering to the requirements outlined in EN ISO 19232-1:2019 is essential for

maintaining the integrity of industrial X-ray films and the accuracy of inspection outcomes.
