inspection required, where the inspection shall be
made, and the number of plates to be inspected. The
number will depend on the service to which the
plates will be subjected. For example, all plates
intended for pressure vessels and dynamically loaded
structures such as rail and highway bridges, cranes,
and missile service towers shall be inspected. In
the case of plates for statically loaded structures
such as buildings and storage tanks, inspection
shall be on the basis of heats in which the sample
size shall be in accordance with the governing
specifications or standards for tensile tests.
However, the plates intended for ultrasonic
inspection shall not be the same as those from which
the tensile specimens were taken. For economy,
plates should be inspected at the mill following
final processing and before shipment. However, in
some instances, this may not be expedient. Where
critical, the designer shall specify in detail the
occasion for inspection in the construction process.
**************************************************************************
This section includes procedures, methods, standards, and descriptions of
equipment which shall be used for [mill] [shop] [field] inspection of
rolled plate, including clad materials which are 13 mm 1/2 inch or thicker,
through which interpretable ultrasonic penetration is possible. Inspection
of plate shall be [individually.] [by lots. The sample size shall be two
plates per lot. A lot shall be defined as being all plates in a 50 mm 2
inch thickness interval rolled from the same heat. Any overlay, pressure
cladding, or weld deposit shall be included in the thickness
determination.] Ultrasonic inspection shall be made to detect the
following defects:
a.
[Internal laminar discontinuities.]
b.
[Lack of bond between roll or explosive bonded sheet.]
c.
[Lack of fusion between welded overlays and base plate.]

SUBMITTALS
**************************************************************************
NOTE: Submittals must be limited to those necessary
for adequate quality control. The importance of an
item in the project should be one of the primary
factors in determining if a submittal for the item
should be required.
A "G" following a submittal item indicates that the
submittal requires Government approval. Some
submittals are already marked with a "G". Only
delete an existing "G" if the submittal item is not
complex and can be reviewed through the Contractor's
Quality Control system. Only add a "G" if the
submittal is sufficiently important or complex in
context of the project.
For submittals requiring Government approval on Army
projects, a code of up to three characters within
