CONTAINED IN VOL. 01.05, 2017 Specifies a basic procedure of ultrasonically inspecting cylindrical forgings with bores from the bore surface.

1.1This practice covers a basic procedure of ultrasonically inspecting cylindrical forgings with bores from the bore surface.

1.2This practice applies to the manual testing mode. It does not restrict the use of other testing modes, such as mechanized or automated.

1.3This practice applies to cylindrical forgings having bore sizes equal to or greater than 2.5 in. [64 mm].

1.4This practice is expressed in inch-pound and SI units; however, the inch-pound units shall apply unless the purchase order or contract specifies the applicable “M” specification designation (SI units). The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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.

1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
