Non-destructive testing (NDT) is a crucial process that various industries use to evaluate the integrity and safety of structures, equipment, and materials. NDT reports provide valuable insights into the condition of the object being tested. However, they are not created equal. So, to get the most out of reports, you should know what to look for and how to analyze them effectively. When you pay attention to these critical factors, you’ll extract maximum value from NDT reports and make informed decisions for your business. You can also visit to get assistance. Here are three key things to analyze in NDT reports:

Testing Procedure

If your company relies on NDT for its operations, you need to analyze the testing procedures included in reports. Testing procedures provide critical information about how the testing was conducted and whether it affected the accuracy or reliability of the results. Examining these procedures will also help you to determine if the testing was performed according to industry standards and regulations. If errors or inconsistencies in the testing process may have affected the results, you can have the testing redone by qualified personnel.

Essential Variables

Essential variables refer to the critical parameters that must be controlled and measured during testing to obtain accurate and reliable results. Analyzing these variables in NDT reports is crucial because they can significantly impact the testing results.

For example, in ultrasonic testing, the essential variables include the ultrasonic wave frequency, pulse duration, gain setting, and probe type. In radiography testing, the essential variables include the source-to-film distance, the exposure time, and the film type. In each case, controlling and measuring these essential variables is vital to avoid mistakes.

Analyzing the NDT report will help you to find out if the essential variables were measured correctly during the testing process. You’ll need this information to determine if the results are reliable.

Map Of Indications

A map of indications visually represents the object being tested and areas where potential defects or anomalies are detected. It’s also known as the scan or inspection image and is created during testing.

Analyzing the map of indications in NDT reports will enable you to determine the location, size, and shape of any potential defects or anomalies in the tested object. This information can be helpful because it will help you know the severity of the defects and whether they pose a risk to the integrity and safety of the object.

Furthermore, analyzing the map of indications in NDT reports can help you to identify any patterns or trends in the defects or anomalies detected. With this information, you can identify the potential root causes of the defects and develop effective corrective actions to prevent similar defects from occurring in the future. Additionally, it will help you evaluate the effectiveness of the testing method and equipment used. If the map of indications shows areas of poor quality or incomplete coverage, it may be advisable to conduct further tests.


Analyzing Non-Destructive Testing (NDT) reports is essential to maintain the integrity and safety of structures, equipment, and materials. Understanding the testing procedures, essential variables, and a map of indications will help you determine if the results are reliable. Contact a professional if you find it challenging to understand the language used in these reports. They’ll examine the reports and provide the insights you need to make the right decisions for your business or organization.
