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.
