What should be the minimum legibility requirements for recorded ultrasonic test results?

Recorded ultrasonic test results must meet clear, unambiguous, and interpretable standards to ensure that all stakeholders, including technicians, engineers, and quality assurance personnel, can accurately understand and analyze the information provided. This requirement is crucial as ultrasonic testing often involves complex data related to material integrity, thickness measurements, and defect characterization. If the records are not clear and easy to interpret, it could lead to misunderstandings or misinterpretations, potentially compromising safety or quality standards.

The clarity of recorded data enables effective communication among team members and helps maintain compliance with industry standards and regulations. Unambiguous records also facilitate consistent data analysis and comparison across different tests or inspections, which is vital for maintaining the quality assurance process and ensuring the reliability of test results.

This standard of legibility directly supports the overall objective of NDT, which is to detect flaws without causing damage to the test material, while also ensuring that any potential issues are properly documented and communicated.
