entitled "Performance" and "Qualification of
Inspection and Nondestructive Examination (NDE)
Personnel" through "NDE Personnel Qualification" and
renumber paragraphs as necessary. Rarely will a
project require 100 percent testing of welds by NDE
methods. The designer must determine the required
methods and the extent of inspection and testing and
must indicate the extent in this or other sections
of the project specifications or on the project
drawings by notes, nondestructive test symbols, or
other means. The referenced applicable publications
and Army Technical Manual, "Welding Design,
Procedures and Inspection," TM-5-805-7, will be used
for guidance in determining inspection and testing
requirements. The specifications or project
drawings must clearly indicate which joints require
100 percent NDE inspection, which joints require
random NDE inspection, and which NDE methods are to
be employed for each joint. For random inspection,
the project drawings must indicate the location,
number of joints, and minimum increment length of
weld that will be subject to NDE inspection without
predisclosing the exact spots to be examined. Joints
not indicated to be tested by NDE methods shall be
subject to visual inspection only. In cases where
the nature of the welding is such as to require
visual inspection only, the requirements for
nondestructive examinations should be deleted from
these paragraphs and from paragraph entitled
"Qualification of Inspection and Nondestructive
Examination (NDE) Personnel."

NOTE: Information based on the two tables must be
developed and included in each project
specification. Tables must clearly define the
systems to be inspected and the type of NDE
required. Specify 100 percent NDE when required by
DM-22 and 49 CFR 195, as covered by paragraph
entitled "Piping Subject to 100 percent NDE."
**************************************************************************
Visual and nondestructive examinations shall be performed [by the
Government] [by the Contractor] to detect surface and internal
discontinuities in completed welds. [Employ the services of a qualified
commercial inspection or testing laboratory or technical consultant
approved by the Contracting Officer.] Visually examine welds
[Radiographic,] [Liquid penetrant,] [Magnetic particle,] [or] [Ultrasonic]
examination shall be required as indicated in Tables [IV] [and] [V]
attached to this section [or in accordance with other sections where
detailed requirements are specified]. Random NDE testing applies to ASME
B31.3 and ASME B31.4 piping unless specified otherwise. When examination
and testing indicates defects in a weld joint, a qualified welder shall
repair the weld in accordance with the paragraph entitled "Corrections and
Repairs" of this section.
