ASTM E2375 is a standard practice that covers the minimum requirements for ultrasonic examination of wrought products, including wrought metals and components made through forging, rolling, or machining. The practice applies to products with a thickness or cross section of at least 6.35 mm (0.250 in.). For wrought aluminum alloy products, Practice B594 also applies, and the official ASTM description specifies certification in accordance with both practices. The engineering drawings, material specifications, or other applicable documents establish the acceptance criteria. Contractual requirements and authorized engineering direction may add to or modify the practice’s requirements.
The scope of ASTM E2375 includes:
- Material type: Wrought metals and wrought metal products, including forged, rolled, and machined components.
- Purpose: Establishing minimum requirements for ultrasonic examination of wrought products.
- Properties evaluated: Internal material soundness through the examination and evaluation of ultrasonic indications; the practice does not establish one universal property value for every product.
- Testing method: Ultrasonic examination performed according to the applicable procedure and product requirements.
- Results: Ultrasonic examination findings evaluated against the acceptance class and criteria specified in the governing documents.
- Test limitations: The practice does not establish one universal acceptance limit for every product. Applicable drawings, specifications, or other documents must define the acceptance criteria.
- Use conditions: The examination must follow the applicable contractual requirements, authorized engineering direction, and relevant safety requirements.
- Applications: Quality control, product inspection, manufacturing verification, and acceptance of wrought metal products.
What are the Uses of ASTM E2375?
ASTM E2375 helps manufacturers and engineers establish a consistent approach to ultrasonic examination of wrought metal products. The practice supports inspection and acceptance decisions by providing a framework for examining components against specified requirements. Its uses include:
- Supporting quality control during the manufacture of wrought metal products.
- Examining forged, rolled, and machined components for relevant discontinuities.
- Providing ultrasonic examination information for product acceptance.
- Supporting inspection requirements in purchase orders, engineering drawings, and material specifications.
- Helping manufacturers document whether examined products meet the applicable acceptance criteria.
- Supporting inspection programs for wrought products used in demanding engineering applications.
Which Materials Can Be Tested Under ASTM E2375?
ASTM E2375 covers wrought metals and wrought metal products that meet the practice’s thickness or cross-section requirements. These include forged, rolled, and machined metal parts. Depending on the product’s material, geometry, examination requirements, and relevant contractual documents, certain wrought metal products such as wrought aluminum alloy products may also require the inclusion of Practice B594 in the evaluation. The applicable product forms and acceptance requirements must always be checked against the current edition and applicable purchase order or specification.
Why is ASTM E2375 Important?
Ultrasonic examination helps assess the internal soundness of wrought metal products without requiring destructive sectioning. ASTM E2375 establishes a consistent basis for performing this examination and evaluating the indications against defined acceptance requirements. This matters when manufacturers and purchasers need documented evidence that a component meets the requirements specified for its intended application. Because the practice provides five acceptance classes but relies on the applicable documents to establish acceptance criteria, selecting the correct requirements is essential to interpreting results properly.
