Final answer:
Codes like ASME and ASTM establish acceptance criteria for NDE methods to assess material integrity without damage, varying by method and industry.
Step-by-step explanation:
Codes that determine the acceptance criteria for Nondestructive Evaluation (NDE) techniques are essential for ensuring the integrity of materials and structures without causing damage. These criteria vary depending on the specific NDE method, the industry, and the application. Some common standards are developed by organizations such as the American Society for Testing and Materials (ASTM), the American Society of Mechanical Engineers (ASME), and the International Organization for Standardization (ISO).
For example, the ASME Boiler and Pressure Vessel Code specifies acceptance criteria for NDE techniques such as radiographic, ultrasonic, and magnetic particle inspections for pressure vessels. Another widely applied standard is the ASTM E165 for liquid penetrant testing, which outlines test methods and acceptance levels.
Professionals must be familiar with relevant standards and codes to accurately evaluate the results of NDE methods, ensuring safety and compliance with regulatory requirements.
