ASTM A/AM: Standard Specification for Straight-Beam Ultrasonic Examination of Rolled Steel Plates for Special Applications. ASTM A – acceptance standard clarification. Hello, I’ve recently begun working at an alloy manufacturing company in Japan, and one of our. Ultrasonic testing can be carried out using the following standards: • ASTM A • ASTM A (Level A – max mm;. Level B – max 60 mm; Level C – 20 mm).

I would just like to double-check that I’m interpreting the condition correctly.
Could anyone help clarify the following information? An equivalent standard is one which covers the qualification and certification of ultrasonic nondestructive examination candidates and which is acceptable to the purchaser.
The test shall be performed either by direct contact, immersion, or liquid column coupling. Are you an Engineering professional?

Lauren, Your interpretation is correct. Link to Active This link will always route to the current Active version of the standard. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. If I’m understanding correctly that the qstm diameter is to be no smaller than 3 inches regardless of the thickness of the plate, this test seems very easy to pass as you would need quite a large indication to be outside the bounds of the circle.
You’re right, the size limit is liberal. It’s easy to join and it’s free. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Combining values from the two systems may result in non-conformance with the standard. In regards to your first paragraph, if you completely lose backwall over more area than can be encompassed in a 3″ dia. Three levels of acceptance standards are provided.

I appreciate your assistance! Ast, method will detect internal discontinuities parallel to the rolled surfaces.
Thicker plate is allowed to have larger laminations, hence why the term is “whichever is larger”. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. A has 3 different acceptance levels A, B, C. UT inspectors at my company normally reject plates on the basis of much smaller indications, so my superior was surprised to see such a broad allowance. The amplitude linearity of the apparatus to be used shall be checked by positioning the transducer over the depth resolution notch in the IIW or similar block.
Resources Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor.
