a This Section of the Code contains requirements,
methods, and techniques for nondestructive examination
NDE, which are Code requirements to the extent that
they are specifically referenced and required by other
Code Sections or referencing documents. These NDE
methods are intended to detect surface and internal imperfections
in materials, welds, fabricated parts, and components.
Nonmandatory Appendix A of this Article
provides a listing of common imperfections and damage
mechanisms, and the NDE methods that are generally
capable of detecting them.
b For general terms such as inspection, flaw, discontinuity,
evaluation, etc., refer to Mandatory Appendix I.
c New editions of Section V may be used beginning
with the date of issuance and become mandatory 6
months after the date of issuance unless modified by
the referencing document.
d Code Cases are permissible and may be used, beginning
with the date of approval by ASME. Only Code Cases
that are specifically identified as being applicable to this
Section may be used. At the time a Code Case is applied,
only the latest revision may be used. Code Cases that have
been incorporated into this Section or have been annulled
shall not be used, unless permitted by the referencing
Code. Qualifications using the provisions of a Code Case
remain valid after the Code Case is annulled. The Code
Case number shall be listed on the NDE Procedure or Personnel
Certification, as applicable.
