What is EN ISO 13948:2019?

EN ISO 13948:2019 is an international standard that provides guidelines for the evaluation and measurement of image quality in radiographic images. It specifically focuses on the assessment of image sharpness, noise, and contrast. This standard is applicable to both analog and digital imaging systems used in industrial radiography.

The Importance of EN ISO 13948:2019

Accurate evaluation of image quality is crucial in radiography as it directly influences the interpretation of test results. EN ISO 13948:2019 ensures that images produced by radiographic techniques meet certain quality standards, which is essential for reliable inspections. This standard helps in determining if the radiographic equipment is functioning properly, enabling technicians to make appropriate adjustments when necessary.

Evaluation Parameters of EN ISO 13948:2019

EN ISO 13948:2019 outlines specific parameters for each aspect of image quality assessment. One of the key parameters is image sharpness, which refers to how well-defined the boundaries of objects are in the image. Another important parameter is image noise, which indicates the level of random variations in brightness or pixel values. Additionally, contrast, which determines the difference in grayscale between adjacent areas, is also evaluated according to this standard.

Benefits and Implementation of EN ISO 13948:2019

Adhering to EN ISO 13948:2019 offers numerous benefits. It helps ensure consistent and accurate radiographic interpretations, leading to enhanced detection of flaws or defects. By providing a standardized approach, this standard facilitates effective communication between different stakeholders, such as equipment manufacturers, inspection agencies, and customers. Implementing EN ISO 13948:2019 also aids in improving the overall safety and quality of radiographic inspections.
