Historical Version s – view previous versions of standard. This procedure covers the standard and acceptance standards for straight-beam, pulse-echo, ultrasonic examination of rolled carbon and alloy steel plates.

The amplitude linearity of the apparatus a587 be used shall be checked by positioning the transducer over the depth resolution notch in the IIW or similar block. The inspection shall be performed in an area free of operations that interfere with proper performance of the test.

The test shall be performed a5578 by direct contact, immersion, or liquid column coupling. Grid scanning shall be conducted along a continuous perpendicular line on the center.


All discontinuities causing complete loss of reflection shall be recorded. This abstract is a brief summary of the referenced standard. It is informational only and not an official part of axtm standard; the full text of the standard itself must be referred to for its use and application.

ASTM does not give any warranty express or implied or make any representation that the contents of this x578 are accurate, complete or up to date. The method will detect internal discontinuities parallel to the rolled surfaces.

Three levels of acceptance standards are provided. Supplementary requirements are provided for alternative procedures.

ASTM A – acceptance standard clarification

An equivalent standard is one which covers the qualification and certification of ultrasonic nondestructive examination candidates and which is acceptable to the purchaser. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.


Combining values from the two systems may result in non-conformance with 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
