ASTM E2297

ASTM E2297 is a technical guide for the use of UV-A and visible light sources and meters in liquid penetrant and magnetic particle methods. It helps users apply the right lighting and measurement approach when evaluating indications under these inspection processes. By focusing on light sources, meter use, and suitable viewing conditions, the standard supports more consistent examination practices and more dependable results in quality control and nondestructive testing workflows.

Overview of ASTM E2297

The official title of ASTM E2297 points to a guide rather than a test method, which means it is intended to help users select and use UV-A and visible light sources and meters appropriately. In practice, it provides technical direction for lighting conditions that affect liquid penetrant and magnetic particle examinations. This makes the standard useful for organizations that need repeatable inspection conditions, proper instrument use, and clearer interpretation of surface indications during routine or production inspection.

Common use cases of ASTM E2297

This standard is commonly used where liquid penetrant or magnetic particle methods rely on controlled UV-A or visible light for indication evaluation. It is relevant to inspection setups that include dedicated lamps, light meters, or viewing stations used during nondestructive testing. ASTM E2297 may also support procedures, work instructions, and equipment verification practices in environments where consistent illumination is important for reliable examination and documentation of results.

Benefits of using ASTM E2297

Using ASTM E2297 can help improve consistency in lighting-related inspection conditions and support better compliance with internal and external quality requirements. It gives procurement, inspection, and QA teams a common reference for choosing and using light sources and meters tied to penetrant and magnetic particle methods. That can reduce variation in examination practice, improve confidence in results, and support more controlled product evaluation and risk management.
