This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation:A 578/A578M–96 (Reapproved 2001) Designation: A578/A578M – 07
Standard Specification for
Straight-Beam Ultrasonic Examination of Plain and
1
CladRolled Steel Plates for Special Applications
This standard is issued under the fixed designationA578/A578M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.

rolled carbon and alloy plain and clad steel plates, ⁄8 in. [10 mm] in thickness and over, for special applications. The method will
detect internal discontinuities parallel to the rolled surfaces. Three levels of acceptance standards are provided. Supplementary
requirements are provided for examination of clad plate and for alternative procedures.
1.2 Individuals performing examinations in accordance with this specification shall be qualified and certified in accordance with

covers the qualification and certification of ultrasonic nondestructive examination candidates and which is acceptable to the
purchaser.

3.1 The inquiry and order shall indicate the following:
3.1.1 Acceptance level requirements (Sections 7, 8, and 9). Acceptance Level B shall apply unless otherwise agreed to by
purchaser and manufacturer.
3.1.2 Any additions to the provisions of this specification as prescribed in 5.2, 13.1, and Section 10.
3.1.3 Supplementary requirements, if any.
4. Apparatus
4.1 The amplitude linearity shall be checked by positioning the transducer over the depth resolution notch in the IIW or similar
block so that the signal from the notch is approximately 30 % of the screen height, and the signal from one of the back surfaces
is approximately 60 % of the screen height (two times the height of the signal from the notch). A curve is then plotted showing
the deviations from the above established 2:1 ratio that occurs as the amplitude of the signal from the notch is raised in increments
of one scale division until the back reflection signa
